The Document Foundation has announced LibreOffice 26.8.3, the third maintenance update in the 26.8 series of its free and open-source office suite, with fixes for 45 bugs, including application crashes, document compatibility issues, and desktop integration problems.
In Calc, developers fixed a crash triggered when rearranging column fields in a pivot table. Writer no longer crashes when inserting a section around an existing nested section. Impress resolves crashes related to pasting unformatted text into presentation notes. Draw and Impress also receive a fix for crashes involving copying, pasting, and interacting with comments.
Another correction fixes a problem introduced in LibreOffice 26.8 that caused the Navigator to enter a continuous loop when encountering grouped shapes in document footers, resulting in sustained CPU usage. A separate fix resolves a hang when editing the default table style.
Microsoft Office compatibility has also improved. Calc’s TEXTBEFORE and TEXTAFTER functions now behave consistently with their Excel counterparts. Moreover, PowerPoint presentations containing numbered lists with explicit starting values now display the correct numbering sequence instead of repeating the same number across multiple items.
The update also fixes an issue where valid non-Zip64 packages larger than 2 GiB were wrongly identified as corrupted files. In Calc, the formula input line no longer appears empty in some situations, even when the selected cell contains a formula.
For Linux users, LibreOffice 26.8.3 fixes an issue where the application ignored the configured menu bar color in KDE Plasma. A GTK3-specific bug that prevented users from selecting and editing paragraph styles other than the current one through the sidebar has been fixed. Icon theme fallback behavior now accounts for dark user interfaces.
On macOS, LibreOffice now uses the operating system’s native UI font. The release also restores document signing with X.509 certificates and fixes problems when sending documents as attachments through Thunderbird.
Other corrections include properly handling merged cells when copying HTML tables, fixing the positioning of bullet points in Impress, and correcting alphabetical sorting for Kurdish using the Latin/Hawar alphabet. Japanese collation support has also been repaired.
In addition to these fixes, the Document Foundation is urging users to upgrade because LibreOffice 26.2 will reach end of life on November 30, 2026. After that date, the older series will no longer receive bug fixes or security updates.

LibreOffice 26.8.3 is available for download from the official website. Linux users can also get the update through their distribution’s repositories once the updated packages become available.
