In April 2011 Oracle stopped development of OpenOffice.org and laid off the remaining development team. Its reasons for doing so were not disclosed; some speculate that it was due to the loss of mindshare with much of the community moving to LibreOffice while others suggest it was a commercial decision. In June 2011 Oracle contributed the trademarks to the Apache Software Foundation. It also contributed Oracle-owned code to Apache for re-licensing under the Apache License, at the suggestion of IBM (to whom Oracle had contractual obligations concerning the code), as IBM did not want the code put under a copyleft license. The developer pool for the Apache project was seeded by IBM employees, who as of 2014[update] continued to do the majority of the development.
The project was accepted to the Apache Incubator on 13 June 2011, the Oracle code drop was imported on 29 August 2011, Apache OpenOffice 3.4 was released 8 May 2012 and Apache OpenOffice graduated as a top-level Apache project on 18 October 2012.
IBM donated the Lotus Symphony codebase to the Apache Software Foundation in 2012, and Symphony was deprecated in favour of Apache OpenOffice. Many features, including the sidebar and bug fixes, were merged. The IAccessible2 screen reader support from Symphony was merged for inclusion in the AOO 4.1 release, although its first appearance in an open source software release was as part of LibreOffice 4.2 in January 2014.
By December 2011, the project was being called Apache OpenOffice.org (Incubating); in 2012, the project chose the name Apache OpenOffice, a name used in the 3.4 press release.
A tool for creating and editing mathematical formulae, analogous to Microsoft Equation Editor. Formulae can be embedded inside other Apache OpenOffice documents, such as those created by Writer. It supports multiple fonts.
Apache OpenOffice inherits its handling of file formats from OpenOffice.org (excluding some supported only by copyleft libraries, such as WordPerfect support). There is no definitive list of what formats the program supports other than the program's behaviour. Notable claimed improvements in file format handling in 4.0 include improved interoperability with Office Open XML (import only).
Use of Java
Apache OpenOffice does not bundle a Java virtual machine with the installer, as OpenOffice.org did, although the suite still requires Java for "full functionality."
As an Apache project, Apache OpenOffice is under the governance of the Apache Software Foundation.
The project has no regular release schedule; it eschews time-based release schedules, releasing only "when it is ready". This contrasts with the approach of LibreOffice, which plans feature releases every six months.
Apache OpenOffice 3.4

Oracle released a beta version of OpenOffice.org 3.4 on 12 April 2011, including new SVG import, improved ODF 1.2 support, and spreadsheet functionality.
A few days after the beta release, Oracle cancelled development of the proprietary Oracle Open Office derivative and, a few months later, announced that stewardship of OpenOffice.org would be transferred to the Apache Software Foundation.
With the donation to Apache, development slowed while the foundation moved the codebase and infrastructure to its servers. Apache OpenOffice 3.4 was released on 8 May 2012. Apache OpenOffice 3.4 differed from the thirteen-month-older OpenOffice.org 3.4 beta mainly in license-related details: as much code and fonts under licenses unacceptable to Apache was removed as was possible. Language support was considerably reduced, to 15 languages from 121 in the last Oracle OpenOffice.org version. Java is not bundled with the software. 3.4.1, released 23 August 2012, added five more languages, with a further eight added 30 January 2013.
Apache OpenOffice 4.0
Apache OpenOffice 4.0 was released July 23, 2013. Features include merging the Symphony code drop, reimplementing the sidebar-style interface from Symphony, improved install, MS Office interoperability enhancements, and performance improvements. 4.0.1 added nine new languages.
Apache OpenOffice 4.1
This version was released 29 April 2014. Various features lined up for 4.1 include comments on text ranges, IAccessible2, in-place editing of Input Fields, interactive cropping, importing pictures from files and other improvements.
The project strongly recommends all downloads be made from its own download page, which supplies binaries from the project's SourceForge page. SourceForge reported 30 million downloads for the Apache OpenOffice 3.4 series by January 2013, making it one of SourceForge's top downloads; the project claimed 50 million downloads of Apache OpenOffice 3.4.x as of 15 May 2013, slightly over one year after the release of 3.4.0 (8 May 2012), and 85,083,221 downloads of all versions by 1 January 2014.
As of May 2012 (the first million downloads), 87% of downloads via SourceForge were for Windows, 11% for Macintosh and 2% for Linux; statistics in the first 50 million downloads remained consistent, at 88% Windows, 10% Macintosh, 2% Linux. As of April 2014, Apache OpenOffice has been downloaded 100 million times in a period of two years. 
LibreOffice also reuses some Apache OpenOffice code, acknowledging 4.5% of commits in LibreOffice 4.1 as coming from Apache contributors.It is also rebasing its LGPL version 3 codebase on the Apache OpenOffice 3.4 source code release,[clarification needed] to allow wider (but still copyleft) licensing under MPL v2+ and LGPL v3+.
