Overview of changes leading to 1.8.8
|
||||
Tuesday, August 14, 2018
|
||||
====================================
|
||||
- Fix hb-icu crash on architectures where compare_exchange_weak() can
|
||||
fail falsely. This bug was introduced in 1.8.4.
|
||||
https://bugs.chromium.org/p/chromium/issues/detail?id=873568
|
||||
- More internal refactoring of atomic operations and singletons.
|
||||
- API changes:
|
||||
The following functions do NOT reference their return value before
|
||||
returning:
|
||||
* hb_unicode_funcs_get_default()
|
||||
* hb_glib_get_unicode_funcs()
|
||||
* hb_icu_get_unicode_funcs()
|
||||
This is consistent with their naming ("get", instead of "reference")
|
||||
as well as how they are used in the wild (ie. no one calls destroy()
|
||||
on their return value.)
|
||||

||||
