A Feature-Rich Update
LibreOffice 25.8 brings a multitude of new features for Writer, Calc, Impress, Draw, and the entire office suite. This version enhances productivity, compatibility with other formats, and overall performance. It also includes new functions, improved accessibility options, and more powerful scripting tools.
This overview summarizes the main LibreOffice 25.8 improvements by module, so users can quickly identify what changes in text editing, spreadsheets, presentations, drawings, file formats, accessibility, and automation.
Major Updates in Writer
The text editor Writer has received significant improvements for layout, text management, and change tracking.
These changes are useful when preparing structured documents such as reports, long texts, technical documents, or files that require careful review. The new layout and spacing options give users more control over how text appears on each page.
Notable additions include:
- New option to prevent hyphenation of the last word on a page by moving the entire line to the next page.
- End settings for paragraph, column, page, and double-page.
- Precise control over minimum, desired, and maximum spacing between words.
- Enhanced tooltips in the Navigator displaying total word and character counts, including subsections.
- Command to insert a paragraph break before a table.
- Shortcut to convert fields to plain text (Ctrl + Shift + F2).
- New field indicating the number of pages until the next numbering restart.
- Improved change tracking, with the ability to restore rejected changes and better manage interdependent changes.
- Image redaction function directly from the Auto-Redact tool.
- Language setting for certain punctuation marks to enhance correction and readability.
For collaborative writing, the improved change tracking can help when several edits depend on each other. The ability to restore rejected changes also makes document review more flexible. The image redaction function adds a practical option for hiding sensitive visual information directly from the Auto-Redact tool.
Performance Gains in Writer
Loading complex documents is faster thanks to:
- Optimized layout for large files.
- More efficient processing of documents with tracked text movements.
- Accelerated deletion of large tables.
- Faster rendering for documents written right-to-left.
These performance gains are especially relevant for long Writer documents, files with many tracked changes, large tables, or right-to-left text. They aim to make editing and navigation smoother when documents become more complex.
Enhancements for Calc
The spreadsheet software Calc introduces new functions and notable optimizations.
LibreOffice 25.8 improves both formula work and spreadsheet handling. Users working with large XLSX files, many conditional formats, charts, comments, or imported CSV files benefit from clearer options and faster operations already mentioned in this release.
New Functions
Many modern functions inspired by Excel make their debut: CHOOSECOLS, CHOOSEROWS, DROP, EXPAND, HSTACK, TAKE, TEXTAFTER, TEXTBEFORE, TEXTSPLIT, TOCOL, TOROW, VSTACK, WRAPCOLS, WRAPROWS.
These functions help reshape, split, combine, and extract data in spreadsheets. They can be useful when preparing tables, cleaning imported data, or organizing information across rows and columns.
Other Improvements
- Customization of operators in conditional formatting icon sets.
- "Clear AutoFilter" option in the context menu.
- CSV import dialog with a checkbox to show or hide it for each import.
- Improved speed for opening and handling large XLSX files, especially with many conditional formats, charts, or comments.
- Faster calculation of row heights and better handling of large charts.
The "Clear AutoFilter" option makes filtering easier to reset from the context menu. The CSV import dialog option also gives users more control when importing text-based data into Calc.
New Features for Impress and Draw
Impress
- Ctrl + Scroll Wheel shortcut to adjust the number of slides per row in sorter mode.
- Support for embedded fonts in PPTX files.
- Ability to copy master slides.
In Impress, these updates improve presentation editing and slide organization. Adjusting the number of slides per row in sorter mode can make it easier to review a presentation visually. Support for embedded fonts in PPTX files helps preserve the intended appearance of presentations that use those fonts.
Draw
- Display of page margins with option to disable via advanced settings.
In Draw, the display of page margins helps users place objects more precisely on the page. The option to disable this display through advanced settings keeps the interface adaptable to different workflows.
General Improvements in LibreOffice
- New viewer mode to open all files in read-only mode.
- Thumbnail previews for background images in page styles.
- Better compatibility with encrypted files and signed PDF documents.
- Proportional resizing of OLE objects, including charts, with or without holding the Shift key.
The new viewer mode is designed for opening files in read-only mode. Thumbnail previews for background images make page style choices easier to identify. Proportional resizing of OLE objects, including charts, helps keep embedded objects consistent while resizing them.

- Import of AutoFilters from Excel XML.
- More accurate rendering of DOC/DOCX documents in Chinese, Japanese, and Korean.
- Correction of multi-level numbering in DOCX.

Scripting and Automation with ScriptForge
The ScriptForge module is enhanced:
- New methods for manipulating cell ranges, context menus, and defined names in Calc.
- Functions for copying controls between dialogs, managing alignment, color, and borders.
- Identical support in Basic and Python.
