What's new in this version:

Writer:
- Content controls: added a new plain text type. blog post
- Content controls: added a new combo box type and PDF export. blog post

Content controls: added titles and tags. blog post
- Now tabs can be edited for multiple paragraphs with different settings at a time. Tabs dialogue (Format ▸ Paragraph... ▸ Tabs) is available even when multiple paragraphs are selected which has different settings. core
- Improved kashida insertion position validation, to prevent inserting kashida between contextually substituted glyphs breaking word shape. core
- Correctly calculate text caret position inside ligatures, and use caret positions from the font when available.
- Fix broken colored Arabic text when enabling Show Formatting Marks.
- It is now possible to define a custom color for Grammar mistakes in the Application Colors dialog (Tools ▸ Options... ▸ LibreOffice ▸ Application Colors). core
- AutoTexts created using "New (text only)" no longer insert a new line at the end of the AutoText. The currently embedded AutoTexts have been adjusted accordingly by explicitly adding a new line at the end of the text. User-created AutoTexts, relying on the trailing new line, should be re-created including the trailing empty paragraph.

Tables:
- Better column deletion when it intersects with merged cells.
- Allow table row/column selection, if last cell starts with a nested table.
- Allow tracked table row/column deletion, if last cell starts with a nested table.

Bookmarks:

Bookmark editing in Insert Bookmark dialog window:
- Bookmark text content can be edited in the dialog. core
- The Bookmark dialog accessed from Navigator ▸ Bookmarks ▸ Right click ▸ Edit... now opens with the clicked bookmark already selected. core
- Hidden _Toc and _Ref bookmarks imported from OOXML are shown as Hidden in the dialog, allowing sorting the not hidden (user-defined) bookmarks before them by a single click on header Hidden.

Colored bookmarks for metadata visualization:
- Show visible marks in custom color defined in bookmark metadata.
- Page number in status bar now uses a range when the view spans several pages.
- Elements can be highlighted on page by hovering over their name in the Navigator sidebar deck.

Spell checking:
- Better recognition of typos, and better suggestions in Danish, Dutch, Estonian, German, Hungarian, Norwegian and Swedish with the improved compound word recognition algorithm of Hunspell spell checker. Hunspell 1.7.2
- Moving text cursor Up/Down triggers pending spell checking of the last modified word.
- Spell checking of plain words of hyperlinks

Keep comment of the corrected words, instead of removing it without being noticed

Bookmark accessibility:
- Screen readers get text equivalent of visible bookmarks.

Bookmark visualization:
- Various improvements of bookmark visibility (see Tools ▸ Options ▸ LibreOffice Writer ▸ Formatting Aids ▸ Bookmarks

Note: this is a continuation to Michael Stahl’s fix for
- ⌶-shape point bookmark (The previous shape, a single vertical line was overlapped with visible page margin at beginning of the paragraphs, also it was very similar to the NBSP and narrow NBSP shading.)
- ][-shape (i.e. double) marks for neighboring bookmark ranges (instead of a single vertical line, which could not be distinguished from point bookmark symbol previously).
- All bookmarks at the same character position are visible now, e.g. instead of a single |, neighboring bookmarks with point bookmarks are shown e.g. as ] ⌶ [ or ] ] ⌶ ⌶ [ [
- Do not show visible marks for hidden _Toc and _Ref bookmarks imported from OOXML, like Microsoft Office does.

Accessibility:
- Images, embedded objects and text frames can now be marked as decorative, which allows assistive technology to ignore them in exported PDFs

Hyperlinks, table of content and other indices keep their language, and with this, their accessibility.

Accessibility checker:
- Add several accessibility checker rules
- Add Rescan button to Accessibility Check dialog
- Make Accessibility Check dialog non-modal
- Automatic (Online) Accessibility Check has been added, which scans for accessibility issues while the user is editing the document. The accessibility status is shown in the status bar. You can enable it in the main menu (Tools ▸ Automatic Accessibility Checking). Currently it is only available when experimental mode is enabled, as it doesn't take all document objects into account

Machine translation:
- Initial machine translation is available, backend by DeepL translate (Mert Tumer, Collabora) core

Performance:
- Cutting hundreds of pages with numbered lists in Writer
- Export to EPUB in Windows
- Opening Writer documents with large tables

Calc:
- Cell input with leading ' apostrophe in cells that are not formatted as Text was changed to always strip the first apostrophe and force the remainder as text content. Previously, the user had to know (or guess) whether an input could be converted to a numeric type (number, date, ...) and prefix only that to force text, but not prefix a textual type that could not be converted, which was confusing and bad UX. The handling is not changed for cells already formatted as Text, where every input is continued to be accepted literally as content and a leading apostrophe is not removed.
- Add support for Kamenický and Mazovia encodings.
- Conditional formatting's begins-with/ends-with/contains are now case-insensitive like the rest of the conditions were.
- Preserve tab characters and line-breaks in cell contents.

- The in-presentation pen function can be turned off with Ctrl + A (on top of the existing toggle Ctrl + P), which should make more presenter devices compatible.
- Objects can be drag-and-dropped in the navigator, allowing reordering and moving them in and out of groups.

Edit Engine:
- Sync kashida insertion algorithm with Writer one to include fixes and enhancements from Writer that other LibreOffice components were missing.
- Fix bad Arabic letter spacing when text starts with left-to-right characters.
- Fix gaps in justified Arabic text when the font does not have usable kashida glyph.

- Add support for switching dark or light mode manually
- When previewing styles in the side bar and the styles menu, use the CTL and Asian fonts set on the style for respective text instead of always using Western fonts.
- Remove redundant File ▸ Recent Documents menu from macOS dock icon.
- An improved version of a single toolbar user interface was implemented, supporting context-aware controls and their customization. It can be activated via View ▸ User Interface... ▸ Single Toolbar. Customization can be done either with a right click context menu actions, or via Tools ▸ Customize... ▸ Toolbars, for various "Standard (Single Mode) - <context name>" targets. For now, context aware controls were added to Writer only. This largely makes the Contextual Single user interface obsolete, and it might be removed in future versions.

Localization:
Improvements to proofing tools and language support:
Dictionaries:
- Ukrainian dictionary was updated.
- Added Persian (fa-IR) dictionary
- Slovenian thesaurus was updated (Martin Srebotnjak, OdprtiTezaver).

Language tags:
- The language list combo-box now accepts input of art-... BCP 47 private-use language tags like art-x-mylang or art-Latn-x-mylang (with every valid script subtag for Latn of course). This is an exception to the otherwise not accepted input of private-use subtags preventing mis-spreading arbitrary private-use tags, to support language attribution of artificial constructed languages.
- Language list entries can be permanently added by dropping an auto-correction file acor_*.dat into the shared or user profile's autocorr/ directory with the corresponding well-formed and valid BCP 47 language tag in its name. The file can be empty (0 bytes length) with no auto-correction data being present, data can be added and edited as usual in AutoCorrect Options. For example, autocorr/acor_de-DE-1901.dat will add the de-DE-1901 tag's language entry that will be displayed as
- German (Germany, Traditional German orthography) {de-DE-1901}
- If the tag in the file name is not a well-formed BCP 47 language tag or not valid, it is silently ignored and no language list entry will be added.
- For information about IETF BCP 47 language tags, see Wikipedia and W3.org
