List of the fixes and improvements in RTP program (dd.mm.yyyy)
+ added functionality
= changed/improved
* fixed
=============================================================================
22.08.2026
* New main configuration could get the path name instead of default "Main" or user-defined name in "Options".

20.08.2026
+ Added the option "Load other configurations" with the choices: never, ask, always. It allows to set the preferred action if there is a saved configuration in a new location.
+ Added the option to create a new configuration file upon exit, if there is no such in current location. Default name of configuration is the last part of path, it can be renamed in "Options".
+ Added the section "Using configurations" in documentation.

30.07.2026
= Improved the logic of using the local ini file without the main ini.
= Increased the length of the "Configuration name" field.

26.07.2026
= Main configuration file rtp.ini in the program's directory uses the name "Main" by default (you can rename it if need). This configuration can be changed when program is started directly in Explorer or by shortcut with default "Start in:" field. It also allows to set the interval of auto update check. In other configurations, this interval is shown in the "Options" dialog, but cannot be changed.
= In the dialogs with graphs (Details of calculation, Specimen displacement) the right-click context menu "Copy image", "Copy text" works in all dialog area, text fields are now non-interactive.

22.07.2026
+ Added the field "Configuration name" in the "Options" dialog. It is useful if you have several configurations in different directories. This name may have up to 30 characters, it is shown in the title when the table is empty. Using a common name of group of specimens would be a good idea.
= If the "main" configuration file does not exist in the program's directory, it will be created during the first update basing on current file. Configuration name and recent list will be empty.
= Clipboard/file content dialog in Windows Vista and later uses the font Consolas, which is more easy to read than traditional Lucida Console.
= Simplified the context menu in the table and dialog fields (shown by right-click or Shift+F10).

12.07.2026
= After successful update, the file history.txt is shown in the dialog window instead of Notepad. It is also available in the menu "Help", "Version history".
= If the configuration file rtp.ini does not exists in current directory, program checks the "main" rtp.ini in the program's directory, which is saved when rtp32.exe starts directly there. It will be a base for new local configurations.

30.06.2026
= Step of calculation of specimen displacement is decreased to 0.25 mcm (was 0.5 mcm).
= Floating point calculations are improved. However, the code is still compatible with Windows XP, which may be used in old scientific devices. In the future, the code may be updated for more modern OS and processors.
= Improved the subsection "Format of formula line" in documentation. Explained the difference between centre dot, usually written as asterisk '*', and plus sign '+', which is also supported.

20.06.2026
= Added the vertical line '|' and underscore '_' to possible signs in a chemical formula, which are counted as space characters.
= Added a remark about the recent AMCSD files which no longer include the density.
= Updated the Web address of Winfit archive in documentation.
= Changed the fabs() call with inline code to speed up the calculations (about 30% quicker indexing).

16.06.2026
+ Added the line "Cell" in the "Settings for indexing by shuffle" dialog, which allows to see and choose the initial cell centring independently of indexing results.
= Added the warning message "Results are unreliable, add more lines" which informs that calculation results are unstable. This and other warnings are explained in the subsection "Estimation of quality" in documentation.
= Left click within the area for basic mark (left of h k l) can select/unselect the basic lines. It works in addition to selection of basic line by key "B" or in the phase menu.
= Sorting by mouse on the table header is performed on mouse release (was on click).

6.06.2026
= If some intensities are less than 1.0 or not present, they are shown with intensity 1 on the stripe chart.
* Fixed some possibly missed h k l combinations when indexing the monoclinic lattice (in particular, 1 1 1 and -1 1 1 for two of basic lines).

1.06.2026
= Added the formula-like names of space groups to the list of skipped words: they may be occasionally mentioned in the AMCSD header.
= Improved the detection of UTF-8 and UTF-16 encoding of data files.
= Added the subsection "Improving accessibility" to "Installation" section in documentation.
= Mark of current field is now "colour" by default for better accessibility.
= When indexing is active, marker and table can be scrolled in usual way (may be slow).
* Increasing the screen height with visible last line (440) did not update the table properly.

15.05.2026
= In "Options", the name of precision field is changed to "Default precision for cards". This value is used for both PDF-2 cards and AMCSD data.
= Improved the search for formula in AMCSD header. Most common formula-like words and cell acronyms are skipped, for example: As, BCC, FCC, HCP, IF, SO, YOU and Roman numerals II...VIII. These words are checked only in the header, you can input any formula in "Theoretical density and 1/mu" dialog.

1.05.2026
= If an opened text file has the commented lines with additional information (after first description line and optional wavelength), they are copied to specimen information, up to 4. Similarly, specimen information is included to the text file at export (Save as, *.txt) as comments.
= When the table is sorted by intensities, the lines with the same I are sorted by ascending of 2th.

12.04.2026
= If a text file is opened when the table is not empty, the request about new data type (with some first lines) is now shown before the question, whether to clear the table or keep it and add new data. This helps to avoid clearing the table by mistake.
= When editing a field in the table, left-click outside of current line but within the table now inputs the field value (you can Undo if need). Left-click somewhere outside the table cancels the input, as before. It may make editing with mouse easier.
= Zero h k l in empty lines are no longer marked by yellow in *.htm files. In non-empty lines, such indices are counted incorrect and marked as before.
* Fixed the unclear warning message that supposed wavelength unit in the text file differs from current unit.

20.03.2026
= If the data in a text file has an error, it can be edited in the same dialog as clipboard data (difference is in lack of the buttons "Update" and "Clear" for file content).
* After copying the text in "Density and 1/mu" dialog to clipboard (by right-click menu), the number of formula units became incorrect.

12.03.2026
= In the "deviation" column, closing the context menu by left-click a line no longer changes the selection of this line. To change, click the line again.

10.03.2026
= Improved the search for a formula in AMCSD file header. In particular, up to 4 formulae can be found and copied. Formula should have at least 2 elements. Roman numerals like "IV", "VI", which may occur in a reference to publication, are detected and skipped.
* Dialog "Density and 1/mu" was not shown without calculated cell volume V (it is not required to calculate only the molar mass M).

8.03.2026
+ AMCSD files may have a chemical formula of mineral in the header, if this formula presents in the title of publication. When reading such file, program uses a heuristic approach to find and copy the formula. You can see it in the "Specimen" or "Density and 1/mu" dialogs.
= If the table has only a single phase, "Density and 1/mu" and "Displacement" dialogs calculate lattice parameters and cell volume V, which is required for these operations, without additional requests.

2.03.2026
= Simplified the questions for details of calculation and specimen displacement. If the table has only a single phase, "Details" will calculate parameters whenever possible.

20.02.2026
= Prevented possible incorrect output of percent of described lines after choosing the result in the "Results of indexing" dialog.
= Text with results in this dialog can be selected by mouse and copied to clipboard.
= If the cell volume V is not defined before the dialog "Theoretical density and 1/mu", the information about it will be shown in the status line at the screen bottom. Calculation of molar mass by the formula is still possible, but if you want to get the density, close the dialog and calculate lattice parameters.
= Operation "Results of indexing" now always restores the originally described lines and their percent, even if the selection of lines after indexing was changed manually or in the "Details" dialog.
* Attempt to choose the results of indexing did not work after calculation of speciment displacement, even if the displacement was not applied.
* Printing used too small font (about twice less than originally designed).

14.02.2026
= Algorithm of decryption of chemical formula can now convert the uppercase letters to lowercase (e.g. AL -> Al), but with low priority, when previous attempts were unsuccessful. This may result in different decoding for different letter cases. Example: "cas" is decoded as "CaS" because lowercase "a" is a part of symbol "Ca"; however, "CAS" will be decoded as "CAs" because "C" is interpreted first and "AS" is converted to "As". Check the formula after Calculate command to fix incorrect symbols.
= In a formula, you can use the coefficients in scientific notation, which may help if a value is copied from external source, e.g. 1.23E-2 (chemists may disagree).

12.02.2026
+ Added the operation "clear specimen data" to the menu "Clear", which removes all specimen-related information including chemical formula, molar mass, density and attenuation length.
= If the chemical formula in the "Theoretical density and 1/mu" dialog has an error, text cursor shows the position of this error. Calculate command also corrects the symbols of elements, when possible.
* Fixed incorrect actions of pressing Enter at the focused buttons Cancel and Help in the dialogs "Correction and precision" and "Theoretical density and 1/mu".

8.02.2026
= In documentation, added the remark about contrast themes to the "Installation" section. In Windows 10/11 contrast of menu and UI can be improved without themes, by selecting in properties of rtp32.exe or its shortcut "Reduced color mode": 8-bit (256) color.
= Some help links (by F1) are changed from subsections to sections with subheadings.

4.02.2026
= Now after indexing you can select/unselect the lines, sort the lines, calculate parameters and see the details, calculate specimen displacement but not apply it. Operations which change data in the table will clear the indexing results, as before.
= Density of the mineral in AMCSD file is shown at the screen bottom, when you open the dialog "Density and 1/mu". To get the number of formula units, first calculate lattice parameters, then input the formula in this dialog but keep "Units" empty. Calculated density may slightly differ from data in the file.
= When storing the chemical formula, program corrects the symbols of elements, e.g. al -> Al.

1.02.2026
= In documentation, added the selected subheadings after headings (the same way as in TOC).
= In documentation, improved the explanation of initial limit for calculation of specimen displacement.

26.01.2026
= During long operations (version update, indexing) mouse cursor changes to "waiting", as recommended for UI. Indexing can be stopped, but check for update cannot: it works until result of check or message about Internet connection error.

24.01.2026
= Note for single element "in normal state at standard conditions" is also added to selected line in information about specimen.

22.01.2026
+ Program now reads the density of the mineral from AMCSD file. It is not shown directly, but can be used to calculate the number of formula units for calculation of theoretical density and 1/mu. To do this, keep the field "Units" empty and input only the chemical formula.

20.01.2026
= When the attenuation length is calculated for single chemical element in normal state of aggregation, a note is added to "Atoms" field, e.g. "Ti (in normal state at standard conditions)".
= When the specimen name is used as a filename in "Save as" dialog, the characters not supported by the file system are removed from filename.

28.12.2025
= Added to documentation: while AMCSD files do not include the number of formula units, they have the density of the mineral, which can be used to calculate this number.

24.12.2025
* Fixed the width of dialog "Data format error" when a wrong line has more than 80 characters.

21.12.2025
= Data and result in the dialog "Theoretical density and attenuation length" can be copied to clipboard using the context menu (right-click outside of selectable fields).
* Fixed the tooltip to "texture" column when calculated texture coefficients.

6.12.2025
= Now the combination Shift+click the "Paste" button works even when clipboard is empty. It shows the empty dialog, you can type some text and update clipboard.

4.12.2025
* Partially fixed the combination Shift+click the "Paste" toolbar button (show clipboard content). However, it will not work when clipboard is empty and the button is inactive. Command Shift+V or menu "Clipboard" always show this dialog.

1.12.2025
* Fixed occasionally missed "Help" command by toolbar button.

28.11.2025
= Changed the reference to AMCSD mineral database in documentation (it was moved to rruff.net domain).
= The files *.dif with diffraction table from AMCSD are added to default list of extensions in the Open dialog. Existing AMS files *.txt can be opened as before: file format is not changed. You may rename them from .txt to .dif for convenience.
= Improved the section of documentation about adding the data to existing table.
= Context menu "Copy" in the dialogs with graphical data can be called in standard ways: by right-click the image, by Context key or Shift+F10 combination. Previously added line "Copy" to window menu became excessive and removed.
= Better logic of closing the context menus by click or Esc improves interaction and decreases blinking.
* Fixed some rarely used keyboard commands: Ctrl+Ins, Shift+Ins, Shift+F1 etc.

12.11.2025
= In the dialogs with graphical data, image and text can be copied to clipboard from context menu by right-click the image.
= Decreased a chance when the program may become unresponsive, if the check for update lasts too long because of slow or unstable Internet connection.
= Context menu to a table line by right mouse button appears after release of the button, as recommended for UI operations. Before it appeared by press, which is counted non-standard.
= Closing this context menu by left-click on current line no longer occasionally starts editing the clicked field. To edit, click the field again.
= Click the "Name" field shows information about specimen.

22.09.2025
+ In the dialogs with graphical data, the text lines with description and results can be selected by mouse and copied to clipboard by "Copy" in the context menu or Ctrl+C command.

1.09.2025
+ Added an option to copy the graphs (stripe or scatter charts and graph of displacement) to clipboard. Click the small icon in dialog title and select "Copy" in the window menu. Only the image is copied, without text description and results. To copy all dialog window, use standard command Alt+PrnSc.

14.08.2025
= Executable file rtp32.exe is built now with an option "address space layout randomization" (ASLR), which was introduced in Vista to increase the OS security and exists in all later Windows versions.
= Update script rtp32upd.cmd also checks the file with atomic masses rtpam.ini and extracts it if this file does not present.

4.08.2025
= If the configuration file rtp.ini is not found (usually when the program is started in a new location), the information message suggests to check the settings and change if need.
* Click on the header "deviation" no longer sorts the table if this column is empty.

22.06.2025
+ Added the "Table" - "Copy" operation, which copies the table and results to Windows clipboard in the text format same as *.par file. Copy can be pasted directly to a document, report or another program session.
= Toolbar is slightly modified: less often used "Save as" and "Copy" operations are moved to drop-down menu of Save button.

26.05.2025
= After texture calculation, standard UI is restored, if you clear the table or open a new file.

20.05.2025
= In the help, added explanation of remarks (exactly) and (non-standard) in the tooltip for wavelength.
* After texture calculation, "calculated lines" (calculated/total) wrongly shown the number of all selected lines instead of lines used to calculate the specimen parameters.

10.05.2025
+ Added the calculation of texture coefficients by Harris method (see "Calculate" menu or Alt+U command). This operation requires some preparation, please read the documentation. It is not fully tested yet, and if some problems will be found, they should be fixed in the next builds.

28.04.2025
= In description of AMS files, added the information how to find the chemical formula and number of formula units.
= In References, added the link to archive with Winfit program, which results RTP can import. However, it is quite old and may work only in 32-bit Windows or virtual machine.
= Added some subheadings to TOC headings (in one line to avoid additional numeration).

20.04.2025
= Read operation is updated for compatibility with 16-bit Unicode. Now the program can read the data files in plain ASCII, UTF-8 or UTF-16 text formats. Results are saved in ASCII or UTF-8 as before.

4.04.2025
= Improved the check of possible problems with help system. While the program can work without help file, it is not recommended. If a problem is with Windows help system, try to open RTP.CHM file in Explorer. If the help file is not found, need to reinstall or update the program. As a last resort, HTML version of help is available on the program's homepage.
= Theoretical density and attenuation length are no longer shown with excessive digits. They are rounded to 4-5 significant digits basing on typical precision of atomic masses and cell volume.
* Specimen displacement dialog sometimes suggested to correct very small value, less than 1 mcm.
* Import of text file could stop on a line with zero data.

31.03.2025
+ Reading a PDF card (in *.aid format) also inputs the number of formula units, if it presents.
= Improved the data input in the table and dialogs: fields with floating point values accept the numbers, signs, decimal sign and also the scientific notation like 2e-4 (0.0002); integer fields accept only the numbers. Other symbols are ignored, it should help to reduce the mistakes of input.
= At the start of indexing, if some required settings are empty, the default values will be used.
* Fixed too large width of main screen in maximised state.

22.03.2025
= Improved the section "Calculate cell data and lines with h k l" in documentation.
= Improved scrolling of the marker when it is below visible area.

20.03.2025
= Improved the information about quality of calculation in the "Details" dialog.

14.03.2025
= Improved the contrast of dotted mark of current field in dark schemes.
* In classic scheme, initial colour mark of current field was too bright.

6.03.2025
= Improved the look of main screen and Clipboard dialog on displays with low resolutions (800x600 and 1024x768).

4.03.2025
* Active/inactive state of toolbar buttons could be lost after resizing of toolbar.

2.03.2025
= Improved the look of uncommon small fonts on small displays; screen size may be increased on displays with resolution more than full HD (1920x1080).

1.03.2025
+ Added the button Apply to font dialog: it allows to change the screen font on-the-fly and confirm change by OK or restore previous font by Cancel.
= Improved the version update script to prevent infinite loop when rtp32.exe is read-only.
= Improved updating of the list of recent files.
* Fixed occasional incorrect size of screen font, resulting in improper cut of characters.

22.02.2025
* Button Cut could remain active when cut operation is not available.
* Shift+Tab didn't move the position of current field on empty line.

20.02.2025
= Stripe and scatter charts now always show full interval of 2th precision (green area), even for small deviations. It allows to see the proportions of deviations/precision.
= For data pasted from clipboard, typographical signs "minus" (0x2212) and "en dash" (0x2013), often used as minus sign in publications, are counted as common minus '-'. In particular, negative indices with such signs are now pasted correctly.
= Improved the logic of show/hide local menus by left-click in Windows 11 24H2.
= Up and Down keys now scroll the table to marker position, if it was not visible. Mouse wheel works as before: moves the marker within screen, then scrolls the table, or scrolls the table without marker. Shift+wheel always scrolls the table.
* Mean line on the stripe chart could look solid at some combinations of scheme / desktop theme, same as ordinary stripe. Now it is always dashed.

8.02.2025
= Improved the positions of local menus to prevent overlapping field names.
+ Added a simple example of indexing to documentation in the section 6.6.

1.02.2025
= Executable rtp32.exe is no longer counted as potentially unwanted in Windows 10/11, so the built-in update and links are returned back.
= The order of hiding the buttons, when the toolbar should be shortened because of small font, is slightly improved.

28.01.2025
= Check for update and manual update are temporarily disabled to prevent the false positive detection of Microsoft Defender Antivirus. They will be enabled after resolve of the problem. Until that, please update the program manually by unpacking the rtp32.cab file (see documentation). You can download the last program archive on the home page using a web browser or by QR code in the About dialog.

22.01.2025
= UI improvements: increased the contrast of current colour field in dark themes Aquatic and Dusk; Undo can also be called by Alt+Backspace; font list no longer shows vertical fonts (with @ sign).

16.01.2025
= Deviation in the table is shown with 4 decimal signs, when 2th rms dev is less than 0.003 and requires 4 signs (not often for experimental data, typical for theoretical).
* Fixed possible overlapping of X-axis values on the stripe chart, if deviation is less than 0.001 degree.

12.01.2025
= Operations "Indexing by shuffle" (Indexing, Alt+I) and "Indexing by known h k l" (By known h k l, Alt+B) are separated in main menu and have their own settings and toolbar buttons.
= Number of visible toolbar buttons decreases if screen font is small, so full toolbar cannot fit the screen. Operations of hidden buttons remain in the main or context menu.

8.01.2025
= Improved the look of some chart lines and toolbar icons in high contrast themes.

5.01.2025
= Improved the look of "click to copy" text blocks in documentation.
* Fixed some results after indexing: for shuffle, "Cancel" calculates the last successful cycle (even if it was not the best); for known h k l, only "OK" button is shown.
* Old button names could remain in dialogs (side effect of updating clipboard dialog).

4.01.2025
= Improved the look of documentation in high contrast themes, added visual effect of copying.

1.01.2025
+ Added the operation "Update" to clipboard content dialog. It allows to update the clipboard after editing, when you need to paste data somewhere else, like a list of lattice parameters to calculate cell data and lines. In addition, this dialog now shows tabulations and allows to input this symbol (Ctrl+Tab).
= Clipboard dialog can be called any time (in menu or Shift+V), even with empty clipboard.
= Operation "Angles by h k l" in menu is renamed to "Lines by h k l", key command Alt+A. Full name of operation is "Calculate cell data and lines with h k l".
* Fixed the background of information fields in the dialogs when using high contrast themes.

24.12.2024
= In documentation, added the default values to "Options", added a note about program sessions in "Installation". Fixed the spelling and grammar errors, rephrased some text lines.

16.12.2024
+ Dialog "Calculate lines for known h k l" allows to paste the parameters from clipboard with specified length unit "a = 356.6986 pm". Angstrom is default unit, "nm" and "pm" are also accepted. Text line with parameters may include the number of formula units "z=4".
+ Documentation has many text examples, which can be copied and pasted to this dialog as a part of calculation of theoretical density and attenuation length.
+ Example in the section "Calculate attenuation length for multi-phased specimen" includes the text data, which can be pasted to a spreadsheet (e.g. MS Excel).

8.11.2024
+ Added the key command Ctrl+(Num*) to restore the default font size (14pt).
= Commands Ctrl+Up, Ctrl+Dn move the marker between different phases in the table.
= Improved the example "Calculate attenuation length for multi-phased specimen" in documentation.

18.09.2024
+ Expanded the section "Calculate attenuation length" in documentation. It includes the calculations for powder phase with porosity and for multi-phased specimen, where part of calculations is performed in external spreadsheet, with examples.
= Parameter 1/mu calculated in the "Theoretical density and attenuation length" dialog is always shown in millimetres for consistency with "Correction and precision" dialog. Before it might be shown in different units, usually micrometres.

24.08.2024
= Attempt to paste the data from clipboard, when data format is not recognised, now shows the clipboard content dialog. You can edit the data and paste it here. If format is still not accepted, you will see the error dialog, as before.
= Improved navigation in the help system, numeration of the sections is shown in more traditional way. Added the screens of charts (Details of calculation) and graph (Calculate specimen displacement).

25.07.2024
= Improved some descriptions of menu and toolbar buttons shown in the status line.

26.06.2024
= Formula line in the dialog may be longer than reserved description size (68 character), it can be scrolled by left/right keys. However, it will be cut when stored in specimen description.
= Added an error message in chemical formula "Too many atoms", when the number of particular atoms in a formula exceeds the current limit of 2000.

24.06.2024
* In rtpam.ini, mix of spaces and tabs in the same line could cause an error in atomic mass.

21.06.2024
= "Copy selected" in the Line menu is inactive when no lines are selected.
* Fixed possible crash when "Copy selected" operation copies a single line.

20.06.2024
= Parameters, which are copied to clipboard for "Calculate lines for known hkl" dialog, may have the names, like a=4.444 alpha=88.88. Greek letters of angles are also accepted.

18.06.2024
+ Clipboard data can now be used to paste the lattice parameters to "Calculate lines for known hkl" dialog. Parameters should be copied in specific way, see the details in help section 5.6 with examples.
+ In chemical formula field, you can write/paste an expression to get its atomic composition, for example, 4CaAl2Si2O7(OH)2*H2O + NaAlSi2O6
  Components should be separated by '+' on basic level; plus cannot be used inside the brackets.
= Number of possible elements (different atoms) in a formula is increased to 16 (was 8).
= Navigation in the help system is improved, added the numbers of sections and previous/next arrows.
* In a formula, centre dot sign incorrectly limited an area of common multiplier, like 2 in 2CuSO4*5H2O
* "Paste line" operation no longer uses the binary data from clipboard after clear of clipboard content. Before, the copied line could be pasted several times even with empty clipboard.
* Fixed the look of large d values: now d > 99 angstroms is shown correctly, d > 199 is replaced with row of asterisks ***** in the table, but is shown in the edit field.

14.06.2024
= Bullet operator (0x2219) is also accepted as a centre dot sign. Some non-standard signs are allowed in a formula, see remark in "Chemical formula" subsection in help.
= Monospace font in HTML help is changed from Courier New to Consolas for better look on mobile devices.

10.06.2024
= Improved the look of clipboard window in Windows 8.1 and earlier versions.

8.06.2024
= Most of Unicode spacing characters (no-break space, thin space, zero-width space etc.) no longer result in error in a formula: they are skipped like a common space. This should solve some problems in decryption when formula is copied from formatted HTML (web page) or PDF publication.

5.06.2024
+ Added an error message "Unsupported character" in chemical formula.
= In chemical formula, the bullet sign (large middle dot, Unicode 0x2022) and dot operator (0x22C5) can also be used as a centre dot (e.g. separator of hydration group), in addition to asterisk and middle dot signs. Sometimes they are used in the ResearchGate publications.

3.06.2024
= Improved the look of graph (right margin, labels on axis X for 4 intervals).

2.06.2024
+ In the About dialog, added the QR code to the home page. It can be used to download the program archive rtp32.cab on a mobile device.

30.05.2024
= Improved the format of *.csv files for spreadsheets like MS Excel. Added the apostrophe sign before the phase marks (1)...(4) to prevent conversion to negative numbers.
= Operation "Clipboard" can also be performed by command Shift+Paste.
= Operation "Copy selected" adds the table header before the lines, like "Copy all".
* Press of Enter key in the clipboard window adds a line break as intended.
* Fixed the background of check box text in dark high contrast Windows themes.

28.05.2024
= Clipboard window also allows simple editing (change or delete some text) before paste.

25.05.2024
= Transfer of lines by clipboard between different program sessions asks less questions and is more logical. See details in help: Clipboard operations, Transfer between sessions.
= Clipboard content dialog may show larger texts up to maximum table size.

22.05.2024
+ Added the operation "Clipboard" to the "Line" menu, also called by Shift+V. It allows to see current content of clipboard, paste data to the table or clear the clipboard.

20.05.2024
= Print operation now uses the Print Setup dialog for compatibility (Registry fix for Windows 11 which shows classic Print dialog instead of UWP Print may be discontinued).
= Field "Name" on the main screen can show the longer specimen name if possible with current font. Before this, visible name was limited by the number of characters in monospace font.

16.05.2024
= Added the button Clear to the dialog about error in format of clipboard data.
= Detection whether the current Windows theme is light or dark is more accurate.

10.05.2024 - RTP 5.0
= If current clipboard data cannot be converted to at least one value, paste operation shows the error message immediately.

+ Paste operation shows the dialog when the format of clipboard data requires the empty table. You can confirm this or cancel and save current table first, or start another RTP session and paste data there.
+ When the clipboard data can be added to current table, dialog shows a few first lines, which helps to see if clipboard content is correct.
= Context tips on the status bar are reset if the mouse is moved out of the program screen.

6.05.2024
= Improved the section "Select the lines for calculations" in documentation.

5.05.2024
= Improved some tips on status bar. In particular, tip for column "#" to choose a phase is shown only for lines which have at least one field, for column "deviation" to select/unselect - if a line is complete and not excluded.

1.05.2024 - RTP 5.0 beta
Main changes:
+ User interface is significantly improved. Now it is possible to use both monospace and proportional fonts like common serif, sans-serif and some decorative fonts as well. Main window can be resized horizontally and vertically. Status bar at the bottom shows many context tips for current mouse position and information about program status. Added the context menu by pressing the right mouse button within the table. Dialog windows are unified, dialog font increased. Added the "retro" colour scheme to remind the good old days of origin of the program.
+ Clipboard operations allow to cut/copy/paste the selected part of edited field, current line, selected lines or all lines in the table. Paste operation supports the same formats as file open; it is possible to copy a part of text with diffractometry data in an external source, then paste and calculate it in RTP. Operation of copy selected lines or table uses the tab separator compatible with spreadsheets.
= Changed or improved some terminology in program UI, for example, "sort" instead of previous "arrange", "phase" instead of "class/phase". Improved some dialog texts and help system, added new information.
* Fixed many bugs and unresolved problems in previous versions.

Beta version still may contain some errors in newly added code. Feedback is welcome!
(list of changed in the previous version 4.x can be found in the last RTP 4.8 archive)
