New spreadsheet functions

Changed spreadsheet functions

  • Functions that allow using regular expressions now correctly honor case-insensitivity flags (?i) / (?-i) in the expression. Note that the default case-sensitivity of the functions is not changed; the affected functions: AVERAGEIF, AVERAGEIFS, COUNTIF, COUNTIFS, HLOOKUP, LOOKUP, MATCH, SEARCH, SUMIF, SUMIFS, VLOOKUP are case-insensitive by default, so the sensitivity only changes after first (?-i) in the regular expression tdf#78840 (Mike Kaganski, Collabora)

Impress & Draw

Performance improvements

  • Speed up: Long operation during typing in list with animations tdf#129708 (Serge Krot, CIB)





  • For numeric types, the current locale for the decimal and thousands separators is taken into account, e.g., 1.234,321 in de_DE becomes 1234, whereas 1,234.321 in the en_UK locale provides the same result. tdf#97983 (Andreas Heinisch)

Core / General

  • Cairo library was replaced with Skia library (Luboš Luňák, Collabora)

Platform Compatibility



  • Windows Default apps button was added to Options ▸ LibreOffice ▸ General, to call Windows file associations management. This button behaves according to Microsoft file association management policy, which is to open "Default apps" on Windows 7, 8, and 8.1; and to show a message telling user how to open that applet manually in Windows 10. This only works with registered application, so would not work for portable or testing (e.g. beta, when not using WRITE_REGSITRY=1 installation option) releases tdf#44462 (Mike Kaganski, Collabora)


On Linux, file://host/ URLs (denoting filesystem resources on a specific host) were in the past sometimes silently treated as smb://host/ URLs denoting resources accessed via the SMB protocol. This is no loner done. If you want to access a file via the SMB protocol, use a smb URL. core commit fa314082a89f917912dd2e610ac19991b84921fa (Stephan Bergman)
