Last updated 02 July 2012.
Apache™ FOP version 1.1rc1 (candidate) was released on 02 July 2012.
The FOP code base is gradually evolving, from Version 0.90, released on 22 November 2005, to Version 1.1, expected to be released during the Summer of 2012. Further releases in the 1.x series and beyond are expected.
FOP releases prior to version 0.90 were based on a different code base. The last release in that series was version 0.20.5, released on 18 July 2003. This earlier series is no longer maintained.
If you are looking for future release dates, keep in mind that FOP is an Open Source project and we're a combination of volunteers (working in our free time) and sponsored contributors (generally focusing on our sponsor's needs). What we have is an idea where we want to go. How fast we get there depends on the available time, on how well our ideas work out while developing and on you! There's a document in the Wiki where ideas for new developments may be registered and documented.
