We are pleased to announce the release of LyX 2.1.5. This is the fifth and final maintenance release in the 2.1.x series.
LyX 2.1.5 is the result of on-going efforts to make our stable version even more reliable and stable. We have fixed a number of bugs and made a number of improvements. Many of these were minor, but there were a few crashes we fixed, too.These are detailed in the announcement <http://www.lyx.org/announce/2_1_4.txt>. Please note that this is the final release in the 2.1.x series. It is intended for users who for some reason do not wish to upgrade to 2.2.x at this time. We strongly encourage all such users to upgrade to this version. Most users should upgrade to 2.2.0. Note also that LyX 2.1.5 is the last release that will support Windows Vista. This is due to the fact that the Windows releases in the 2.2.x series require Qt 5.6, which is not available for Vista. One of the main features of 2.1.5 is its ability to read and write files in the 2.2.x format. Since the conversion process back and forth usually will not leave one with an identical file, however, we do not recommend attempting to collaborate with users of 2.2.x. We strongly encourage all LyX users to upgrade to this version. You can download the sources in tar.gz format <ftp://ftp.lyx.org/pub/lyx/stable/2.1.x/lyx-2.1.5.tar.gz> (also tar.xz <ftp://ftp.lyx.org/pub/lyx/stable/2.1.x/lyx-2.1.5.tar.xz>). There are also some binaries <ftp://ftp.lyx.org/pub/lyx/bin/2.1.5/> available.
