About this page
This is the page with our 5.3 release release notes. It should be final now the 5.3 release version itself has been released. However, might you spot some missing information, then we would appreciate to hear from you. Thanks in advance for your help!
Go to Page Dialog
- Writer has a new dialog for quickly jumping to another page that is available through tdf#83054 (Akshay Deep, Yousuf Philips) ▸ and Ctrl+G.
Table styles were implemented in Writer:
- The "Table Autoformat" feature was extended from one-time formatting only to a full-featured table style: now when the table uses a table style, the style is preserved with edits in the table, including adding and deleting rows / columns / data.
- Import and export of ODF table styles.
- Table styles can be created and assigned to tables in the Styles & Formatting sidebar deck.
- UNO API for working with table styles.
- Undo and Redo support for table styles.
For detailed code changes, see this blog entry. (Jakub Trzebiatowski, GSoC 2016; Miklos Vajna, Collabora; Jan Holešovský, Collabora; Yousuf Philips)
- New drawing tools were added (that were previously available only in Draw and Impress). tdf#101390 (Gülşah Köse)
Improvements in the toolbar
- It's now possible to set the small capitals character property via a toolbar button. blog entry. (Miklos Vajna, Collabora)
Borderless padding is displayed
- Spacing to contents for pages/paragraphs/characters/headers/frames/images will now affect layout even if borders are not defined, allowing for compatibilty with other ODF-producing software. (Justin Luth, SIL)
- The ability to define borderless padding will come in version 5.4. tdf#41542
- Now it's possible to select multiple headings simultaneously and promote or demote their levels in the Navigator window in Writer. To do this, you need to toggle "Content Navigation View", and use the SHIFT or CTRL key for multiple selection. (Michael Stahl) tdf#54834
- New drawing tools were added (that were previously available only in Draw and Impress). tdf#101390 (Gülşah Köse)
- In new installations the default setting for new documents is now Enable wildcards in formulas instead of regular expressions. tdf#88581 (Eike Rathke (Red Hat, Inc.))
- This is for better interoperability with other spreadsheet applications and a better experience for users who are not familiar with regular expressions. Wildcards are more widespread and the large set of regular expression metacharacters often makes queries too complicated for casual users.
- See also ReleaseNotes 5.2 for wildcards.
New spreadsheet functions
Changed spreadsheet functions
- The UI name of EFFECTIVE was changed to EFFECT to be the same as in other spreadsheet applications. tdf#100641 (Eike Rathke (Red Hat, Inc.))
Compatibility with ODF 1.2
ISOWEEKNUM and WEEKNUM_OOO
Releases prior to 5.1 saved WEEKNUM wrongly as ISOWEEKNUM to ODF. Release 5.3 resolves the interim solution introduced with release 5.1 (see ReleaseNotes/5.1#Compatibility_with_ODF_1.2). (Eike Rathke (Red Hat, Inc.))
- When importing ISOWEEKNUM, if the call uses one parameter it is kept as the correct ISOWEEKNUM.
- If the call uses two parameters it is determined if the second argument mode is a literal numeric value unequal to 1 in which case it is mapped to ISOWEEKNUM with one argument, as the old WEEKNUM function implemented exactly that for those modes.
- If the second argument is something different, i.e. a numeric value 1 or an expression, the call is mapped to the WEEKNUM_OOO compatibility function introduced in LibreOffice 5.1.
- WEEKNUM_OOO is now saved as ORG.LIBREOFFICE.WEEKNUM_OOO which releases 5.1 and 5.2 can read.
- Fraction Number Formats (Laurent BP)
- any of
0can be used for any of integer, numerator or denominator format string.
- any of
- any string can be used as delimiter between integer and fraction:
#" plus fraction "?/?will display PI value as
3 plus fraction 1/7tdf#100834
- more accurate representation of fraction with a new algorithm tdf#99996 (Wolfgang Jäger)
- new default formats with forced denominator tdf#100592
- if denominator has less digits than places, it is now left aligned tdf#102507: with format
# ?/???value 3.5 is displayed as
3 1/2(with two spaces after fraction), instead of
3 1/ 2(old behavior)
- format options available through UI dialog ▸ ▸ and Sidebar
Default Cell Styles
- Default cell styles are loaded from a file in the user profile (Jaskaran Singh (GSoC))
- Syntax is based on ODF and loaded through orcus
- Defining own default cell styles is now easy
- New and improved default cell styles, tdf#90937 (UX team, Jaskaran Singh)
- Median is added to functions available in pivot tables, useful for data fields and for row/column fields (subtotals) tdf#61700 (Tamás Zolnai)
- Only ODS file format is supported to save/load such pivot tables.
- Merge non empty cells tdf#30456 (Laurent BP)
▸ ▸ brings a new option:
- before LibO 5.3, if content was detected, it was possible to move it as text into the first cell. If not content was just hidden but not removed.
- from LibO 5.3, a new option is available: empty hidden cell so that formulas refering to these cells will be updated.
- Functions ( tdf#67974. ▸ ) can now be searched from the available list
- Calc now supports scrolling through the Scroll key tdf#46200.
- Images inserted via tdf#65356 (Samuel Mehrbrodt, CIB) ▸ ▸ can now be linked instead of embedded in the document.
- Slide properties content panel in sidebar for master slide mode. tdf#89466 (Susobhan Ghosh, GSoC 2016; Katarina Behrens, CIB; Yousuf Philips)
When launching Impress, a Template Selector allows you to choose a Template to start with (Akshay Deep, GSoC; Samuel Mehrbrodt, CIB)
- Two new default templates: Vivid and Pencil:
- All existing templates have been improved (Francisco Adrián Sánchez)
- New arrow endings, including Crow's foot notation's ones. Also availible in other apps. (Yan Pashkovsky, Dipankar Niranjan) tdf#93782 tdf#92152
- Firebird has been upgraded to version 3.0.0. It is unable to read back Firebird 2.5 data, so embedded firebird odb files created in LibreOffice version up to 5.2 cannot be opened with LibreOffice 5.3. Since a future version of firebird will have a backwards compatibility module, some future version of LibreOffice (embedding this future version of firebird) will also be able to open these older files.
- Embedded firebird switched to Firebird's "archive" format, which is version and endianness independent, so this issue won't happen again.
- ODB files created by LibreOffice < 5.3 can be manually converted to LibreOffice 5.3 format by using Firebird 2.5 to convert the data to archive format, and replacing the database data within the ODB by the archive format version. To do this, install a stand-alone Firebird 2.5, and use its "gbak" tool to convert the file "database.fdb" to "database.fbk" within the odb file. Don't forget to remove the .fdb file.
- Trend line (regression) equation:
- Y name (default "
f(x)") and X name (default "
x") can be replaced by names defined by the user tdf#100547 (Laurent BP)
- Y name (default "
- Dynamically-sized integral
intdnow allows sub/superscripts. (Takeshi Abe) tdf#53472 tdf#102268
- New command "Evaluated At" in "Brackets" section of Elements window has been added. (Takeshi Abe) tdf#44839
- Improved MathML import (Takeshi Abe)
- Improved MathML export (Takeshi Abe)
Core / General
- Closing LibreOffice will no longer kill active UNO connections (Samuel Mehrbrodt, CIB). tdf#102274
- A new cross-platform text layout engine that uses HarfBuzz for consistent text layout on all platforms (Akash Jain, GSoC 2016; Khaled Hosny) tdf#89870
- OpenType layout is now supported on all platforms, and default OpenType features are enabled for all languages.
- Graphite layout is now supported on macOS as well, not only Linux and Windows.
- OpenType layout features can be controlled using the syntax previously only supported for Graphite fonts.
- Improved Kashida justification for Arabic script.
- Improved vertical text layout for CJK scripts to use HarfBuzz instead of the home grown solution(s).
- All text layout now goes through HarfBuzz, there is no longer any distinction between so-called simple and complex scripts.
- Many Windows-only and macOS-only text layout bugs have been fixed.
- Improved and consistent calculation of inter-line spacing across platforms (Khaled Hosny) tdf#55469
- Enable vertical “left to right” block direction, needed for traditional Mongolian and Manchu (Khaled Hosny) tdf#33278
Change of color palettes
see this blog entry
- Fix recent colors
- The custom palette is newly added, which allows colors to be added directly in the area style dialog
- Custom palette makes the manipulation of factory settings via ▸ ▸ ▸ obsolete ‒ and hence we deleted this option
- The palettes gallery, web, cmyk, and scribus were removed because of the non-standard and rather arbitrary collections with inappropriate names
- Tango and html palettes received minor updates for labels and arrangement of colors
- The standard palette was also refreshed. The first row now starts with 12 shades of gray followed by 12 basic colors from the HSV color wheel. The next rows are variations of these basic colors in respect to saturation and luminance by 66%, 50%, and 25%. The final 12×8 arrangement fits perfectly into our color picker grid
- The palette breeze has been added to the default set. It comprises all values known from the KDE human interface guidelines as an alternative to tango
- Completely new is the tonal palette. It aims to provide a set of colors with the same luminance respective color contrast
- The palette freecolour-hlc based on the CIE LAB color model has been added. Its purpose is to provide a cross-media safe set of colors targeting expert publishers
- The bundled
libxmlseclibrary has been upgraded to 1.2.23, including our "OOXML Relationships Transform Algorithm" implementation upstream. blog entry (Miklos Vajna, Collabora)
- Added support for PDF signature import/export. blog entry. (Miklos Vajna, Collabora)
- Added support for PAdES signing of PDF files. blog entry (Miklos Vajna, Collabora)
- Added support for XAdES signing of ODF files. commit (Tor Lillqvist, Collabora)
A safe mode has been added which starts LibreOffice temporarily with a fresh user profile and helps to restore a broken configuration. (Armin Le Grand, CIB; Samuel Mehrbrodt, CIB)
It can be started with one of the following methods:
- Using the menu: ▸
- Using the
--safe-modecommand line option
- On Windows: Using the start menu entry LibreOffice (Safe Mode)
- The help text will now be rendered in the default platform font if possible (i.e., Segoe UI under Windows, Ubuntu under Ubuntu and Cantarell under Fedora), for greater consistency. (Adolfo Jayme Barrientos)
Office URI Schemes support
- Libreoffice now supports the following registered Office URI Schemes (Mike Kaganski, Collabora) (commit 1 commit 2):
- Also, a new custom Libreoffice-specific scheme is introduced:
- Currently, the default save folder parameter is ignored.
- The schemes handler is registered in the OS by the installer under Windows. MS-specific schemes are only registered if Open MS files with Libreoffice checkboxes are checked (commit)
- This allows, e.g., for better integration with SharePoint.

New Import filters
- StarOffice binary files (.sdc, .sda and .sdw) can again be imported, via libstaroffice (Laurent Alonso)
- This filter is written from scratch and it is at an early development stage. So it should be able to convert simple files but it could (and probably will) fail badly on more complex ones.
- Zoner Callisto/Draw files (version 4-5) can now be imported, via libzmf (Aleksas Pantechovskis, David Tardon)

The Extension Manager now provides a better user experience and accessibility. tdf#103146 tdf#102004 (Muhammet Kara, Pardus; Yousuf Philips)
- Support for 32px icons (extra large) for the toolbar. Currently only Breeze icons have 32px icon variants available. (Tomaž Vajngerl, Collabora)
- Support for SVG icons, however because of some minor issues and there is no icon theme bundled with LibreOffice that contains SVG icons, this is considered experimental. (Tomaž Vajngerl, Collabora)
- Redesign of the Colors, Gradients, Hatching and Bitmap tabs and the addition of a Pattern tab. tdf#94551 (Rishabh Kumar, GSoC 2016; Katarina Behrens, CIB; Heiko Tietze; Yousuf Philips)

- Everyone can now improve accessibility as almost all a11y relations are now easily editable with Glade. tdf#87026 (Muhammet Kara, Pardus)
This release features the first source release of LibreOffice Online - which provides basic collaborative editing of documents in a browser by re-using the LibreOffice core. Rendering fidelity should be excellent, and interoperability match that of LibreOffice. This is however, fundamentally a server service, best installed and configured by someone au-fait with SSL certificate creation, and is most useful when integrated with another solution.
Public LibreOffice Online Docker image
You can grab the latest docker image from Docker Hub here: https://hub.docker.com/r/libreoffice/online
Or grab it like this:
$ docker pull libreoffice/online:master $ docker run -t -d -p 127.0.0.1:9980:9980 -e "domain=<your-dot-escaped-domain>" --cap-add MKNOD libreoffice/online:master
This docker image does not work on Ubuntu 14.04 LTS, because Ubuntu 14.04 LTS has missing kernel compile option CONFIG_AUFS_XATTR=y, which is leading to setcap not working on docker’s aufs storage. Upstream bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1557776
- Many updates and improvements in contents (Gabor Kelemen, Olivier Hallot, Lera Goncharuk, Adolfo Jayme Barrientos, Jean Spiteri, Andras Timar)

New languages/locales with locale data
Available as default document language and for locale specific formatting.
Additional languages in the language list
Available for text attribution.
- Silesian [szl-PL], tdf#101540 (Eike Rathke (Red Hat, Inc.))
- Hungarian Rovas [hu-Hung-HU], tdf#97406 (Eike Rathke (Red Hat, Inc.))
Incorporation of other languages
Our goal is to support as many languages as possible. We would like to thank the following people for voluntary translation into LibreOffice and helps in preserving their native languages:
Improvements to proofing tools and language support
- European Portuguese language auto-correction files were synchronized with Brazilian Portuguese files tdf#97439 (Tiago Santos)
- adds 1936 automatic replacement entries, 11 new two caps word exceptions and 1726 new abbreviations.
- Croatian sentence exception list updated: added 66 new abbreviations.
- Proofing tools for German language (de-AT, de-CH, de-DE) have been largely improved (tdf#105396):
- The spell-check dictionary now contains over 258,000 words. This new version adds over 7,300 new words.
- The hyphenation patterns have been improved. The new version includes 700 corrected and new hyphenation patterns. Hyphenation uses the new COMPOUND feature and contains a list with over 69,000 words and compounds.
- The thesaurus now contains over 146,000 words in over 37,000 meaning groups. The new version adds ~11,000 new words. The thesaurus now includes 11,400 associations and 1,900 antonyms.
Scripting: Python and Basic
Access2Base, the Basic library for Base users, is now available in its version 1.6.0 (Jean-Pierre Ledure).
The main improvements are related to the management of (long) binary fields with the
AppendChunk methods. Also the scope of the
CopyObject method has been extended to the duplication of complete tables between distinct databases. As an experimental feature, the tables might belong to databases built above distinct database systems (f.i. from HSQLDB to MySql or the opposite). Additionally a spanish translation of the UI has been provided by Iñigo Zuluaga. Full documentation is available on the documentation website.
- The Emoji One font has been bundled for Emoji support (Akshay Deep) commit
- Windows installer (MSI) now supports Restart Manager feature available on Windows Vista and newer (commit) (Mike Kaganski, Collabora). This allows to automatically close and restart processes locking files that the installer needs to replace. Previously, only a list of these processes was shown, and the user needed to close/reopen them manually. Without closing/reopening, a system restart after installation is required.
These features are not finalized, yet can be tried by early adopters. They can be enabled in▸ ▸ ▸ ▸ .
- Four toolbar modes have been added to make it easy for users to switch the visible toolbars, which can be done in tdf#101249 (Szymon Kłos, GSoC 2016; Yousuf Philips) ▸ .
- Implementation of the Extended Toolbar framework (see this blog entry) (Szymon Kłos, GSoC 2016; Jan Holešovský, Collabora; Samuel Mehrbrodt, CIB; Yousuf Philips)

- In Impress, the Standard (Single Mode) toolbar was added to provide a single toolbar alternative to the default double toolbar arrangement and it contains the most used function, insert, and formatting operations. It can be activated by enabling with tdf#92218 (Yousuf Philips) ▸ ▸ .
- In Writer, the section Manage changes was added on the Sidebar
- Introduction of the "Default Shapes Panel" in the new Shapes Deck (currently experimental) for Draw (see this blog entry). tdf#87643 (Susobhan Ghosh, GSoC 2016; Katarina Behrens, CIB; Yousuf Philips)
- A toolbar control to insert Emojis has been added tdf#100100 (Akshay Deep, GSoC; Samuel Mehrbrodt, CIB)
- Still experimental and requires to activate ▸ ▸ ▸ ▸
- Currently not working on windows see tdf#105689)
