===================================

We are proud to announce the release of LyX 2.2.3. This is the third
maintenance release in the 2.2.x series.

LyX 2.2.3 is the result of on-going efforts to make our stable version more 
reliable and more stable. We have fixed a number of bugs and made a number 
of improvements. Most of these are relatively minor in themselves, but the combined result of fixing them all has led to significant improvements. We encourage all users of 2.2.2 to upgrade to this version.

  # Adjoining closing Single + double quote becomes double + single quote
    (for English, Swedish and German).
  # French double quotes are converted to << >> in the LaTeX file and to
    double inverted question/interrogation marks in the output, if the font
    encoding is set to [None] or OT1 but the global default is T1.
  # Quote type ignored for LyXHTML: always "English" quotes used.

- Output correct identifier for DocBook XML.

  for a workaround to KDE's bug.)

  inset (bug 6570).

- Fix display and output of math macros with optional arguments appearing
  in the optional argument of another macro.
