- A threading issue that caused random segfaults on some platforms from
the testsuite was fixed in test_capi.
- Reverted fix for Bug #1379994: Builtin unicode_escape and
raw_unicode_escape codec now encodes backslash correctly.
This caused another issue for unicode repr strings being double-escaped
(SF Bug #1459029). Correct fix will be in 2.5, but is too risky for 2.4.3.
- Ubuntu bug #29289: Fixed a bug that the gb18030 codec raises
RuntimeError on encoding surrogate pair area on UCS4 build.
