 Overview of changes in GLib 2.57.3
 ==================================
 
+* G_GNUC_MALLOC’s definition has been tightened up to match an updated
+  definition from GCC. Many uses of G_GNUC_MALLOC which were previously
+  appropriate may cause miscompilation with newer GCC versions. Check your uses
+  of it against the updated documentation. See #1465.
+
+* Many minor documentation fixes.
+
+* Fix for gint64 and int64_t compatibility on macOS and BSD. See #972.
+
+* Fix free space metadata on some file systems (notably FAT). See #328.
+
+* Support installed-tests with our Meson build system. See #1444.
+
+* Forbid @filename@/@basename@ in glib-mkenums templates, which is a change to
+  its long-standing behaviour (which was long-standing nonsensical). See !241.
+
+* Various stat() fixes on Windows. See #1452, #1476.
+
 * MinGW-w64 ABI warning: In case you build 64 bit glib without LFS support by
   passing --disable-largefile (not the default) and use GStatBuf, you need to
   rebuild your application as the size of GStatBuf has changed for this case.
-  See #1476
+  See #1476.
+
+* Improve TAP compatibility of g_test_incomplete(). See #1474.
+
+* Change fallback preferences when loading icons. See !72.

+ #1488 ‘O_CLOEXEC’ undeclared (first use in this function)
+ !241 glib-mkenums: forbid @filename@/@basename@ in fhead and ftail

+ #1476 g_stat - possbile memory corruption causing SEGFAULT
+ !199 Update TLS documentation
+ #1474 g_test_incomplete() makes test_case_run() return FALSE
+ #1475 glib/tests/atomic.c test_types() trips -Werror=bad-function-cast on Debian armel

+ !220 date test: Use g_test_skip(), not g_test_incomplete()
+ #1467 malloc difference causes refstring test to fail on FreeBSD
+ !230 gbookmarkfile: Fix some more minor leaks when metadata elements are repeated
+ #1466 Not Able to Build glib 2.57.2 in Mingw-w64 x64 bits
+ #1433 test_posix_parse: assertion failed (g_time_zone_get_abbreviation (tz, 0) == "UTC"): ("LMT" == "UTC")
+ #1446 Follow-up from "Document difference between g_assert() and g_assert_*() wrt G_DISABLE_ASSERT"
+ !206 grefstring: Avoid an unnecessary NUL assignment
