[ FLTK 1.1 | FLTK 1.2 | FLTK 1.3 | FLTK 1.4 | FLTK 1.5 | FLTK 2.0 | FLTK 3.0 ]
This page provides a dynamic look at all Software Trouble Reports ("STRs") that have been filed and accepted through the Bugs & Features page. If you would like to contribute code to implement any of the RFEs below, please consult the Configuration Management Plan for the coding standards we follow and then post your changes to the corresponding RFE.
FLTK 1.1.x is the former stable development branch. It is no longer being maintained, and any bug fixes will be applied against FLTK 1.3.x and/or 1.4.x. We recommend using the active FLTK 1.4 branch instead.
FLTK 1.2 is not available any longer. Please use the latest 1.1.x release for a stable release, or 1.3.x for a stable release with UTF-8 support and other new features.
FLTK 1.3 is the previous stable branch based on FLTK 1.1.10. It added internationalization, UTF-8 (Unicode), printing support, Doxygen based documentation, and several new widgets including Fl_Native_File_Chooser, Fl_Table, and Fl_Tree. Note: FLTK 1.3 is no longer in active development but got some important bug fixes (and for instance new macOS support).
FLTK 1.3.11 (released on Feb 05, 2025) is presumably the final release of branch 1.3.
FLTK 1.4 adds even more features to the FLTK 1 release series. This is the development branch where new features are added and bugs are fixed as of November 2024.
FLTK 1.4.2 (released on Feb 23, 2025) is the current stable release.
FLTK 1.5 is the working title for the next release after 1.4.x. This is the future development branch where new features will be added and some old stuff will be removed. This branch will also use more modern C++ features, very likely a new menu system, and more.
There is no release schedule yet.
FLTK 2.0 was an experimental branch that never attained stability and is mostly dormant. Development of 2.0 was focused on a new C++ API using namespaces which provides support for UTF-8 (Unicode) text, enhanced UI scheme support and device and OS abstraction for easier porting and better printing and off-screen rendering support. THIS SHOULD NOT BE USED FOR REAL PROJECTS!
