[icu-support] Announcement: ICU4C 50.1.2 (Layout Engine only)

[Steven R. L. <sr...@ic...>]

[Update- sorry, I forgot to change the subject. This email pertains to
50.1.2]

Dear friends and users of ICU,

We published ICU4C 50.1.2.
This is a maintenance updates of ICU4C 50.1.1.  It is a single-purpose fix,
for ticket #9826 <http://bugs.icu-project.org/trac/ticket/9826> where the
Layout Engine ABI was broken in 50.1.1.

If you are not using the ICU Layout Engine, you do not need to upgrade to
this version as there is no change from 50.1.1.

(Note: If you *are* using the ICU layout engine, you may want to consider
trying HarfBuzz, which has an ICU API-compliant wrapper for existing ICU
Layout Engine now being tested.  HarfBuzz has and will have much better
support going forward. For more information, please join the HarfBuzz
mailing lists and continue the discussion there:
http://www.freedesktop.org/wiki/Software/HarfBuzz )

ICU4C 50.1.2 files and a list of changes are available at
http://site.icu-project.org/download/50

Regards,
Steven Loomis for the ICU Project

Does it mean that ICU 50.1.2 is ABI-compatible with ICU 50.1 and ABI-incompatible with ICU 50.1.1?
If users have built applications (linked against libicule.so) with ICU 50.1.1, then they should rebuild them after upgrade of ICU?

Yes, but only for the ICU layout engine. There was no ABI change in the
common & i18n libraries that most people use.
