Public release of LyX version 2.5.1
===================================

We are proud to announce the release the LyX 2.5.1, the first maintenance
release in the 2.5.x series.

This release fixes a number of mostly minor bugs in 2.5.0. One important fix
concerns crashes when exiting LyX on OSX, specifically when documents are still
open. We have also fixed a handful of bugs with the new input method support.
If you should encounter any more, please do let us know.

If a file from an earlier version of LyX is opened *and saved* with any version
of 2.5.x, then the original file will automatically be backed up. The backup
file will be found in the backup directory, if one is set under
Tools> Preferences> Paths
or else in the same folder as the original file, if no backup directory is set.

If you think you may have found a bug in LyX 2.5.1, either email the developers'
mailing list (lyx-devel at lists.lyx.org), or open a bug report at
  https://www.lyx.org/trac/wiki/BugTrackerHome
Please specify if the behavior you are reporting is different from behavior in
a previous LyX version. Please note that we have had to disable registration
for new accounts due to spam. If you would like an account, email the LyX
developers' list.

If you have trouble using LyX or have a question, consult the documentation
that comes with LyX (under Help) and the LyX wiki, which you will find at
https://wiki.lyx.org/. You can also send email to the LyX users' list
(lyx-users at lists.lyx.org).
