From the release notes:
Changes affecting future time stamps
Turks & Caicos is switching from US eastern time to UTC-4 year-round,
modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.
Changes affecting past time stamps
Time in Russia or the USSR before 1926 or so has been corrected by
a few seconds in the following zones: Asia/Irkutsk,
Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi,
Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For
Asia/Yekaterinburg the correction is a few minutes. (Thanks to
Vladimir Karpinsky.)
The Portuguese decree of 1911-05-26 took effect on 1912-01-01.
This affects 1911 time stamps in Africa/Bissau, Africa/Luanda,
Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912
GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32.
(Thanks to Stephen Colebourne for pointing to the decree.)
Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
A new file 'backzone' contains data which may appeal to
connoisseurs of old time stamps, although it is out of scope for
the tz database, is often poorly sourced, and contains some data
that is known to be incorrect. The new file is not recommended
for ordinary use and its entries are not installed by default.
(Thanks to Lester Caine for the high-quality Jersey, Guernsey, and
Isle of Man entries.)
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Africa/Bangui, Africa/Brazzaville,
Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda,
Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo.

Change lookup order during relocation so that
ld_preloads always precede caller (unless caller
is main executable).
Asan needs this change in order to intercept libc->libc
calls.

This is needed to make L work correctly, and bionic tests pass
again, after applying the equivalent of
commit 00aaea3645 there.
It makes the preexisting code that uses __sync implementations
much more useful, although we should no longer be exercising that
code in AOSP.
Specifically fixes:
We were invoking __has_extension and __has_builtin for GCC compilations.
They're clang specific. Restructured the tests.
The __sync implementation was not defining the LOCK_FREE macros.
ATOMIC_VAR_INIT was using named field initializations. These are a
C, not C++, feature, that is not supported by g++ 4.6.
The stdatomic bionic test still failed with 4.6 and glibc with our
questionable LOCK_FREE macro implementation. Don't run that piece
with 4.6.
In L, this is a prerequisite for fixing:

Bug:16513433
Change-Id: I9b61e42307f96a114dce7552b6ead4ad1c544eab
We already had the POSIX strerror_r, but some third-party code defines
_GNU_SOURCE and expects to get the GNU strerror_r instead.
This exposed a bug in the libc internal logging functions where unlike
their standard brethren they wouldn't return the number of bytes they'd
have liked to have written.

GCC assembler allows xyz to be redeclared as weak,
by __weak_alias(xyz, _xyz), while _xyz is undefined.
Clang does not like that but silently generates no code.
It will reject its own .s file if the assembly code is saved first.
Since we have no reason to define xyz or _xyz as weak symbol now,
and _xyz is a macro to xyz, we simplify libC to have only
xyz defined as global.

When enabling debug malloc, the snprintf calls in the linker fails to
update the buffer.
The problem is that snprintf makes a call to pthread_getspecific that
returns a valid pointer, but the data it points to is zero. This should
never happen and causes the snprintf to stop and do nothing.
Temporarily replace snprintf with a different implementation to work
around this issue.

...rather than just what's already mapped in. This seems somewhat
contrary to POSIX's "All pages within the stack described by stackaddr
and stacksize shall be both readable and writable by the thread", but
it's what glibc does.

This speeds up the debug malloc code by using the original unwinding code.
The only catch is that it has to link in the libc++ arm unwind code or
there will be crashes when attempting to unwind through libc++ compiled
code.

For tests that call uselocale(), the locale is stored in the
g_userlocale_key thread-specific key. If freelocale() is called later,
then g_uselocal_key points to a deleted pointer. CTS eventually calls
vfprintf to print the result, which calls MB_CUR_MAX and MB_CUR_MAX
accesses the deleted locale stored in g_uselocale_key, causing unpredictable
errors.
Fixed the tests by calling uselocale() with the old locale before
calling freelocale.
