2.5.2 update 2 vs. 2.5.2

  - The writeable glossary file can now have a .utf8 extension instead
of a .txt one, .txt being still the default

  Bug fixes:

  - When using Remove Tags, some non-OmegaT tags (e.g., %s, depending on
the kind of tags checked in Options > Tag Validation) and some
non-useful spaces could be copied at the end of the segment in the target
document

  - In some rare circumstances, the display of matches in the Fuzzy Matches
pane could be very slow

  - When the Fuzzy Matches pane was closed, the explanation text was
displayed in bold instead of the initial non-bold attribute

  - In TMXs, the end of line was hardcoded as LF, instead of using the
system line separator (e.g., CR+LF under Windows, LF under Linux)

  - In the Android filter, the "do not translate" mark has been corrected

  Localisation updates:

  - Dutch localisation updated to 2.5.2 (UI)

2.5.2 update 1 vs. 2.5.2

  Bug fixes:

  - When the glossary folder wasn't in the default location, the
default writeable glossary file wasn't computed correctly. In addition,
the name of the glossary file was lost on saving when a manual correction
was done in project properties.
