LibreOffice is a free and open source office suite, developed by The Document Foundation. It was forked from OpenOffice.org in 2010.

The LibreOffice suite comprises programs to do word processing, spreadsheets, slideshows, diagrams, maintain databases, and compose math formulae.

It is designed to be compatible with other major office suites, including Microsoft Office,[8] though some Microsoft Office layout features and formatting attributes are handled differently or are unsupported.[9] LibreOffice is available in over 30 languages[10] and for a variety of computing platforms,[8] including Microsoft Windows, Mac OS X 10.4 Tiger or newer, and Linux. It is the default office suite of most popular Linux distributions.[11][12][13][14] Ports for FreeBSD,[15] NetBSD,[16] and OpenBSD are being maintained by contributors to those projects, respectively.[17][18][19]

Between January 2011 (the first stable release) and October 2011, LibreOffice was downloaded approximately 7.5 million times.[20]

Features

Included applications

Module Notes
Writer A word processor with similar functionality and file support to Microsoft Word or WordPerfect. It has extensive WYSIWYG word processing capabilities, but can also be used as a basic text editor.[8]
Calc A spreadsheet program, similar to Microsoft Excel or Lotus 1-2-3. It has a number of unique features, including a system which automatically defines series of graphs, based on information available to the user.[8][21]
Impress A presentation program resembling Microsoft PowerPoint. Presentations can be exported as SWF files, allowing them to be viewed on any computer with Adobe Flash installed.[8][22]
Draw A vector graphics editor and diagramming tool similar to Microsoft Visio and comparable in features to early versions of CorelDRAW. It provides connectors between shapes, which are available in a range of line styles and facilitate building drawings such as flowcharts. It also includes features similar to desktop publishing software such as Scribus and Microsoft Publisher.[23]
Math Math: An application designed for creating and editing mathematical formulae. The application uses a variant of XML for creating formulas, as defined in the OpenDocument specification. These formulas can be incorporated into other documents in the LibreOffice suite, such as those created by Writer or Calc, by embedding the formulas into the document.[24]
Base A database management program, similar to Microsoft Access. LibreOffice Base allows the creation and management of databases, preparation of forms and reports that provide end users easy access to data. Like Access, it can be used to create small embedded databases that are stored with the document files (using Java-based HSQLDB as its storage engine), and for more demanding tasks it can also be used as a front-end for various database systems, including Access databases (JET), ODBC/JDBC data sources, and MySQL, MariaDB, PostgreSQL or Microsoft Access.[8][25]

Supported file formats

LibreOffice Supported file formats

Miscellaneous features

LibreOffice can use the GStreamer multimedia framework in Linux to render multimedia content such as videos in Impress and other programs.

Visually, LibreOffice uses the large "Tango style" icons that are used for the application shortcuts, quick launch icons, icons for associated files and for the icons found on the toolbar of the LibreOffice programs.[33][34] They are also used on the toolbars and menus by default.

LibreOffice also ships with a modified theme which looks native on GTK-based Linux distributions. It also renders fonts via Cairo on Linux distributions; this means that text in LibreOffice is rendered the same as the rest of the Linux desktop.[35]

Licensing

The LibreOffice project uses a dual LGPLv3 (or later) / MPL license for new contributions to allow the license to be upgraded.[36] Since the core of the OpenOffice.org codebase was donated to the Apache Software Foundation there is an ongoing effort to get all the code rebased to ease future license updates. At the same time there were complaints that IBM didn't really release the Lotus Symphony code as open source, even though they promised to. It was reported that some LibreOffice developers wanted to overtake some code parts and bug fixes which IBM already fixed in their OpenOffice fork.[37]

Libreoffice Basic

Libreoffice Basic is a programming language similar to Microsoft Visual Basic for Applications (VBA) but based on StarOffice Basic. LO Basic is available in Writer, Calc and Base. It is written in functions called subroutines or macros, with each macro performing a different task, such as counting the words in a paragraph.[38]

Extensions

LO supports third-party extensions.[39] As of June 2013, the LO Extension Repository lists more than 118 extensions.[40] Another list is maintained by the Free Software Foundation.[41]

Future developments

Android and iOS support

In 2011 it was announced that plans are under way to port LibreOffice to both Android and iOS.[42]

Cloud support

LibreOffice Online will allow for the use of LibreOffice through a web browser by using the canvas element of HTML5. Development was announced in October 2011 and is ongoing. It has not yet been released.[42]

Flat icon set

The new LibreOffice flat icons that will replace the current tango icons

To modernise the aesthetics of the office suite, the icon theme is going to be updated. A flat icon set is being prepared that will replace the current tango icons as the default. The goals of this new icon set are to be flat, monochrome, and scalable rather than bitmap icons.[43]

History

Initial release and early history

LibreOffice Writer

On 28 September 2010, several members of the OpenOffice.org project formed a new group called "The Document Foundation". The Document Foundation created LibreOffice from their former project in response to Oracle Corporation's purchasing of Sun Microsystems over concerns that Oracle would either discontinue OpenOffice.org, or place restrictions on it as an open source project, as it had on Sun's OpenSolaris.[44][45][46][47]

It was originally hoped that the LibreOffice name would be provisional, as Oracle was invited to become a member of The Document Foundation. Oracle rejected requests to donate the OpenOffice.org brand to the project[48] and demanded that all members of the OpenOffice.org Community Council involved with The Document Foundation step down from the OOo Community Council, citing a conflict of interest.[49]

LibreOffice was initially named BrOffice in Brazil. OpenOffice.org was distributed as BrOffice.org by the BrOffice Centre of Excellence for Free Software because of a trademark issue.[50]

Another fork of OpenOffice.org, Go-oo,[51] merged into LibreOffice very early on.[52] Since most Linux distributions already used Go-oo (and just called it OpenOffice) that meant a large number of distributions changed to LibreOffice very early since for them it meant little change. Switching back to OpenOffice would have meant a conscious change and no major distribution took that route.

As a result of the fork of OpenOffice.org into LibreOffice, Oracle announced in April 2011 that it was ending its development of OpenOffice.org and would release the majority of its paid developers.[53] In June 2011, Oracle announced[54] that it would donate the OpenOffice.org code and trademark to the Apache Software Foundation, where the project was accepted for a project incubation process within the foundation.

In June 2011 Google, Free Software Foundation, Red Hat, SUSE, SPI and Freies Office Deutschland e.V. each contributed one employee to The Document Foundation's Advisory Board to serve for an initial term of one year.[55]

History after the establishment of The Document Foundation

By 2013 the founding aims of The Document Foundation were achieved. Hosting infrastructure had been set-up and enlarged to cope with increased demand The Document Foundation was officially as a German non-profit foundation.

As of July 2013 the advisory board of The Document Foundation has 11 members: AMD, Google, Red Hat, SUSE, Intel, Lanedo, King Abdulaziz City of Science and Technology (KACST), Inter-Ministry Mutualisation for an Open Productivity Suite (MIMO), Free Software Foundation (FSF), Software in the Public Interest, and Freies Office Deutschland e.V.[56]

Versions

Two different major versions of LibreOffice are available at any time. The latest version is available for users looking for the latest enhancements while the previous version caters to users who prefer stability.[57]

Release schedule

LibreOffice uses a time-based release schedule for predictability, rather than a "when it's ready" schedule. There has been a major release approximately every four to eight months, aiming for six-monthly. A minor bugfix version of the current and previous release branches is released each month.

The Document Foundation intends to release new major versions of LibreOffice once every six months (and to eventually do so in March and September, with the intention of aligning it with other free software projects).[58]

Version 3.3

Screenshot of LibreOffice Calc 3.3

LibreOffice 3.3.0 Beta 1, which was based on the beta release of OpenOffice.org 3.3, was made available on 28 September 2010 and was downloaded over 80,000 times.[83] The first stable version of 3.3 was released on 25 January 2011.[29] Because The Document Foundation and most of the software's new and former developers considered LibreOffice a direct continuation of OpenOffice.org, LibreOffice 3.3 continued the OpenOffice.org version numbering.

LibreOffice 3.3 features several functions not found in its OpenOffice.org counterpart, mainly as a result of Sun and then Oracle's requirement of assignment of copyright to themselves. Most of the features found in the 3.3 release were directly adapted from several already-created plugins, as well as the Go-oo fork.

Version 3.4

Redesigned Move/Copy Sheet dialog in Calc, LibreOffice 3.4

Version 3.4.0 was released on 3 June 2011.[58][63] Early versions of v3.4 contained some bugs, including compatibility issues with Microsoft Office, and was therefore only recommended as suitable for early adopters.[84] By 3.4.2, the release was considered suitable for enterprises.[85]

Version 3.5

Impress in LibreOffice 3.5.5

Version 3.5 was released on 14 February 2012.[28] LibreOffice can now be installed via a .msi Windows Installer.[66] Another major improvement is the new online update checker. By default, this feature is not yet fully automated.[68]

Version 3.6

With version 3.6, released on 8 August 2012, many import and export features were introduced. [86]. Furthermore, Calc now supports color scales and data bars.

Version 4.0

Writer with the "GNU - I" Persona and showing a comment set for a text range, LibreOffice 4.0.0

Version 4.0 was released on 7 February 2013.[87]. The release plan is defined to (at least) version 4.0.6 in October 2013.[88]

Version 4.1

Version 4.1 was released on 25 July 2013 [89](Public beta on 26 May 2013[76]). This release incorporates more than thousand bug fixes and improvements, including a fix for OOXML handling bugs that caused a crash in Writer. As the first large UI change since forked from OpenOffice.org, a new sidebar feature is introduced. Version 4.1 will also be able to handle older Mac formats applications such as MS Word for Mac, Write Now, MacWrite Pro and AppleWorks.[80][26] Support of obsolete text layout engines has been dropped in favor of Core Text for OSX and HarfBuzz for Linux.[78]

The final release is planned for the end of July 2013.[77].

Version 4.2

LibreOffice 4.2 is scheduled to be released in February 2014.[90] Some changes will happen in Writer and Draw, concerning UI and Import/Export abilities. Also, Calc will be able to access data from online documents.[81]

Users and deployments

The Document Foundation estimated in September 2011 that there were 10 million users worldwide who had obtained LibreOffice via downloads or CD-ROMs. Over 90% of those were on Windows, with another 5% on Mac OS X. LibreOffice is the default office suite for most Linux distributions, and is installed when the operating system is installed or updated. Based on International Data Corporation reckonings for new or updated Linux installations in 2011, The Document Foundation estimated a subtotal of 15 million Linux users. This gave a total estimated user base of 25 million users in 2011.[91] The Document Foundation has set a target of 200 million users worldwide before the end of 2020.[91]

LibreOffice has seen various mass deployments since its inception:

  • In 2003-2004, the Brazilian corporation Serpro started migrating his software to BrOffice (the local version of LibreOffice at the time) with estimated economy of BRL 3,491 Mi (approximately USD 1,200 Mi at the time), and became a case study for similar initiatives in Brazil, particularly in e-government.[92]
  • In 2010, the Irish city of Limerick gradually started migrating to open-source solutions to free itself from vendor lock-in and improve its purchase negotiation power. One of the key aspects of this move has been the use of LibreOffice.[93]
  • In 2011, the administrative authority of the Île-de-France region (which includes the city of Paris) included LibreOffice in a USB flash drive given to students which contains free open source software. The USB flash drive is given to approximately 800,000 students.[42][94]
  • In 2011, it was announced that thirteen hospitals of the Copenhagen region would gradually switch to LibreOffice, affecting "almost all of the 25,000 workers".[95]
  • In 2012, the Greek city of Pylaia-Chortiatis migrated its PCs to use LibreOffice. The local Linux User Group estimated cost savings to be at least 70,000 euros.[96]
  • In July 2012, the Spanish city of Las Palmas switched its 1200 PCs to using LibreOffice, citing cost savings of €400,000.[97]
  • In 2012, the administration of Umbria, Italy, started a project to migrate an initial group of 5000 civil workers to LibreOffice.[98]
  • The U.S. city of Largo has been a long-time user[99] of open-source software using Linux thin clients. Originally using OpenOffice.org, the city of Largo switched to LibreOffice in 2013.[100]
  • In June 2013, the government of the Italian province of South Tyrol will be switching 7000 PCs in administration and "many more thousands" PCs in health services using LibreOffice and ODF.[101]

LibreOffice Conferences

Starting in 2011, The Document Foundation has organized the annual LibreOffice Conference as follows:

  • 2011 – Paris, France – 12–15 October[102]
  • 2012 – Berlin, Germany – 17-19 October[103]
