  • Custom number formats with question mark in decimal part (such as 0.???), to get decimal alignment without '0', are now saved in ODF tdf#40517 (Laurent BP)

Formula engine

Table structured references

tdf#85063 (Eike Rathke, Red Hat)

  • The following restrictions of Table structured references that were present in 5.0 were addressed:
    • The column names must not be present as cell content in the table's header row any more; column-header-less tables are now supported.
      • For this, for new database ranges without header cells or with empty header cell content, internal names are generated, for example Column1, Column2, ...
      • Internal names are imported from OOXML spreadsheet documents and continue to function in formula expressions.
    • Saving to OOXML, structured references are now written (not transformed to A1 notation any more) and the table context is maintained.
    • Saving to OOXML, the defined database ranges are now exported as <table> elements.
  • Modifying header cell content updates the internal table column names.
    • When deleting header cell content, formulas referring the column name continue to function and are still editable using the previous name.
    • When duplicating header cell content, duplicated column names internally are numbered. For example, having two FooBar header cells the column names will be FooBar and FooBar2. This is automatically reflected in existing formula expressions.
    • When inserting columns within a table, numbered column names are internally generated for empty header cells, starting with the column number within the table. For example, inserting two columns before the third column of a table the generated names are Column3 and Column4.
      • The generated column names are updated if text is entered in such an empty cell.
    • All internal column names are unique within one table, which is reflected when displaying existing formula expressions.

Sticky end column/row anchors

tdf#92779 (Eike Rathke, Red Hat)

  • For range references that encompass at least two columns or rows where the end reference points to the last column or row, i.e. AMJ or 1048576, the end column or row is sticky now and not moved when inserting or deleting columns or rows.
  • When inserting columns or rows and updating a reference the end reference would be shifted out of the sheet bounds, the reference is anchored at the last column or row instead of generating a #REF! error.
    • For example a reference B2:B1048575 when inserting two rows will be updated to B2:B1048576.
    • The column or row will become sticky then, in the example row 1048576.
  • A reference like B1048576:C1048576 does not have a sticky end row anchor, because only one row is referenced.

Compatibility with ODF 1.2

Function WEEKNUM strictly complies with ODF 1.2 function definition and ISOWEEKNUM has been introduced. tdf#50950 (Winfried Donkers + Eike Rathke)

  • In the UI the WEEKNUM_ADD function has been renamed to WEEKNUM_EXCEL2003 to point out it exists for interoperability of documents created with Microsoft Excel.
    • Importing such documents created with older Microsoft Excel versions map the WEEKNUM function to WEEKNUM_EXCEL2003
    • Saving to ODF or OOXML writes WEEKNUM, older LibreOffice and OpenOffice.org release map that to WEEKNUM_ADD.
    • For new documents the WEEKNUM function should be used.
  • WEEKNUM now supports all arguments of the second parameter as defined in ODF OpenFormula (ODFF), see http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html#WEEKNUM
  • The ISOWEEKNUM function has been implemented to calculate the week number according to ISO 8601, see http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html#ISOWEEKNUM
  • WEEKNUM_OOO provides compatibility with older LibreOffice and OpenOffice.org releases for cases that can not be mapped to WEEKNUM or ISOWEEKNUM as defined in the standard, specifically if the mode argument is 1 the old WEEKNUM implementation returned a week number calculated as if it was an ISO 8601 calculation but with the week starting on Sunday instead of Monday. This is not covered by any standard.
    • Not offered in the Function Wizard to prevent accidental use. Use it only if interoperability with older LibreOffice or OpenOffice.org releases is required.
    • Currently still saved wrongly as ISOWEEKNUM with 2 parameters for interoperability with older LibreOffice or OpenOffice.org releases.
      • This will be changed in future for release 5.3 and the function will be saved as ORG.LIBREOFFICE.WEEKNUM_OOO, the current 5.1 release is already enabled to read that.

Impress and Draw

A quick look at some of the new features in LibreOffice Impress 5.1

  • Slide navigation and sorting commands were added with corresponding shortcut keys. tdf#91909 (Philippe Jung, Yousuf Philips)
  • Master slide view appears in a different background color to normal view. tdf#87905 (Katarina Behrens, CIB)
  • KDE, XFCE, and Mate ScreenSavers are now also inhibited when presenting (Andrzej Hunt).


Impress Mode selection

Several modes were active in Impress:

  • Page to edit slides content
  • Page Master to edit slides container
  • Notes to add Notes
  • Notes Master to edit Notes container
  • Plan to sketch a presentation
  • Handout to define the handout format
  • Slide sorter to organise presentation

It was hard to navigate between Master / non master modes. Tabs above the working area were jumping right and left, consuming screen space.

Now, two toolbox icons have been added:

  • one to toggle Tab bar visibility. It is hidden by default. Clicking the toggle disables the new Mode Selection tool and restores the previous behaviour.
  • one to Select the Working mode among the 7 modes listed above. It is divided in two zones: top zone is regular mode (dealing with content of the presentation), bottom zone is the Master mode (dealing with container).
New mode selection


Slide Design

Slide Design dialog in Slide ▸ Slide Design now affects all selected (standard) slides. (Caolán McNamara, Red Hat)

Equalize Width/Height

When multiple objects are selected, the right click context menu Shapes submenu now supports Equalize Width and Equalize Height which adjusts the width/height of the selected objects to the width/height of the last selected object. (Caolán McNamara, Red Hat)

Equalize.png

Save Background Image

Right clicking a slide now supports saving a background image to file, this matches the pre-existing set background image option. (Caolán McNamara, Red Hat)

Save-bg.png

View/Edit Control Points

The Shape Properties dialog for enhanced shapes now lists and enables editing the control points. This is in addition to the preexisting mechanism of selecting with the mouse the yellow control handle of the shape, but enables viewing and fine control over the control values. (Caolán McNamara, Red Hat)

Presenter Console

There is now a button on the presenter console to restart the timer of the slideshow without restarting the slideshow itself (see this blog entry) (Miklos Vajna, Collabora; Andreas Kainz)

OpenGL Transitions

All OpenGL transitions have been ported to OpenGL 2.1+, which removes support for very old GPUs but allows a better usage of modern ones. Four new transitions have been added which require OpenGL 3.2+ that exploit these new available features. (Emmanuel Gil Peyrot, Collabora; Tomaž Vajngerl, Collabora)

Math

  • Autoclosing brackets is optional now tdf#43090

Import MathML from Clipboard

(Regina Henschel)

  • The tool “Math Input Panel” in Windows or the context menu of a formula in a browser allow to copy the MathML source to clipboard. The Math module in LibreOffice has got a new item “Import MathML from Clipboard” in menu Tools to import such source and convert it into LibreOffice’s own formula syntax StarMath.
Math Input Panel
MathML source in browser
  • MathML and StarMath have some differences and therefore sometimes corrections on the imported formula are needed, but most of the formula should be correct. If a conversion is not possible, nothing happens.
Import MathML screenshot
  • The import expects, that a <math> element exists, which has an attribute xmlns="http://www.w3.org/1998/Math/MathML".
Result of importing MathML

Base

Ancient SeaMonkey based mozab driver was only used on Windows 32 bit and is removed now. This functionality is replaced with mork driver, that supports Thunderbird address book.

Given that SeaMonkey based mozab driver also provided Outlook and Outlook Express address book integration, that Windows 32 bit only feature is lost for now. Note that Windows 64 bit never supported ancient SeaMonkey based mozab driver.

Chart

Trend Line

  • Exponential and Power trend lines accept negative Y values tdf#70673 (Laurent BP)
  • Improve equation rendering by removing some useless 1: (Laurent BP)
    • polynomial: f(x) = 1x^2 + 1x +1 => f(x) = x^2 + x +1
    • exponential: f(x) = exp( 1 x ) => f(x) = exp( x )

Core

Unicode character input with Alt+X

Some Windows applications, such as Microsoft Word and WordPad, permit the user to input arbitrary Unicode characters by typing an hexadecimal code point (for example, 2026 for ) and then pressing Alt+X. LibreOffice now includes this functionality as well. (Note: This feature adds to the long-existing, equivalent Linux/GTK functionality of pressing Ctrl+⇧ Shift+U+hexadecimal code point.) tdf#73691 (SIL)

Details:

  • Toggles (switches back and forth) between the character before the cursor and its Unicode notation.
  • Intelligently handles combining characters, expanding the entire character immediately.
  • Selection is not necessary, but if used will limit the input to those characters. (Draw/Impress/Calc have the final result selected, but not Writer.)
  • Handles all 16 Unicode planes
  • Available in Writer, Draw, Impress, Calc and Math.
  • Re-assignable keyboard shortcut: Tools ▸ Customize ▸ Keyboard ▸ Category:Options ▸ Function:Toggle Unicode Notation. Defaults to Alt+X assigned at the global level. (Alt+C used for Basque/Dutch/Galician/German/Brazilian-Portugese locales and ⌘ Command+⌥ Option+X used for MacOS).

Improvements in OpenXML filter

  • Export of the modified VBA stream back to binary Microsoft formats and OOXML (Rosemary Sebastian, Markus Mohrhard)
    • There is a new configuration value that allows to control whether to use this feature (by default yes) or switch back to the old behavior of discarding or writing back the unchanged stream
    • The following features are not yet (completely) supported: Protected macros, macro sheets, active x and some of the designer features.
  • Improved export of embedded objects to DOCX and PPTX, including export of Math formulas (Michael Stahl, Red Hat)
  • Numerous other improvements to the Microsoft OOXML import and export filters, the Microsoft Office binary file formats and the RTF format. Details:

Scripting: Python and Basic

Make PyUNO provide more Pythonic behaviour (Matthew J. Francis)

  • Simplifies working with UNO objects by giving the behaviour of Python lists, dicts and iterators to objects which implement UNO container interfaces
  • Applies a custom behaviour to allow objects which implement com::sun::star::table::XCellRange to yield cells and cell ranges by subscript
  • When UNO container objects are addressed in the new style, eliminates the requirement to manually construct Any objects for contained elements which are typed sequences
  • Allows lists and iterators to be passed wherever a UNO method accepts a sequence
  • Relaxes the requirements for initialising UNO structs to allow some members to be skipped when all initialisers are passed by name

PDF: Presentation at Aarhus

bundled Python upgrade

On Mac OS X and Linux, the bundled Python was upgraded to 3.5. Due to Visual Studio compatibility issues, Windows releases still bundle Python 3.3. (David Ostrovsky)

Access2Base updated

Access2Base, the Basic library for Base users, is now available in its version 1.4.0 (Jean-Pierre Ledure).

The main improvements are related to the OutputTo action, which makes it easy now to export the data contained in a Base table or query to Calc, Text or HTML pages. Examples of HTML output are available on the documentation site.

Easy access to Online Documentation of LibreOffice API

There is a theServiceDocumenter singleton available now. It provides the showServiceDocs() method, that opens the documentation of any UNO service passed to it. This allows faster orientation in rapid application development -- esp. in Basic or Python scripting or extension development. There is a short video of a talk at the LibreOffice conference available, which both discusses basic concepts of the UNO API and how the new documenter helps developers.

Feature removal / deprecation

  • Embedding NPAPI Plugins (mostly Adobe Flash) in documents now warns you this is deprecated. It will not work in all environments and support for NPAPI is being removed in the 5.2 release.
  • ActiveX support is considered deprecated and may be removed in the future. If this change negatively affects your Windows application please email the LibreOffice development list with your use case and plan for moving off of ActiveX. We specifically want feedback if you use ActiveX to embed LibreOffice components into your application.
