 Bionic ChangeLog:
 -----------------
 
-Differences between current and Android 2.2:
+Differences between current and Android 2.3:
+
+- <android/api-level.h>: Added new header to define __ANDROID_API__ to
+  a constant integer corresponding to the native API level. This header
+  also exists in the NDK's platform headers.
+
+- <sys/cdefs.h>: Include <android/api-level.h>
+
+- <time.h>: Add timegm(), timelocal(), time2posix() and posix2time()
+
+- <sched.h>: Add sched_getcpu(), sched_getaffinity(), sched_setaffinity(),
+  cpu_set_t and related macros (e.g. CPU_SETSIZE, CPU_ZERO, CPU_SET, ...)
+
+- <unistd.h>: Add ftruncate64().
+
+- <signal.h>: Changed the definition of SIGRTMAX to 64. However, note that
+  sigset_t is only 32-bit and cannot deal with real-time signals.
+
+-------------------------------------------------------------------------------
+Differences between Android 2.3 and Android 2.2:
 
 - <pthread.h>: Add reader/writer locks implementation. Add sanity
   checking to pthread_mutex_destroy() (e.g. a locked mutex will return
@@ -70,6 +89,8 @@
 - <sys/vfs.h>: fixed implementation of fstatfs() (also fixes fpathconf()
   which uses it).
 
+- Added an implementation of pthread_atfork()
+
 - <dlfcn.h>: fixed dlopen() implementation to support dlopen(NULL, ...).
   This allows one to look at the dynamic symbols exported by an executable.

-SHA-1 in C
-By Steve Reid <sreid@sea-to-sky.net>
-100% Public Domain
-
------------------
-Modified 7/98
-By James H. Brown <jbrown@burgoyne.com>
-Still 100% Public Domain
-
-Corrected a problem which generated improper hash values on 16 bit machines
-Routine SHA1Update changed from
-	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
-len)
-to
-	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
-long len)
-
-The 'len' parameter was declared an int which works fine on 32 bit machines.
-However, on 16 bit machines an int is too small for the shifts being done
-against
-it.  This caused the hash function to generate incorrect values if len was
-greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
-
-Since the file IO in main() reads 16K at a time, any file 8K or larger would
-be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
-"a"s).
-
-I also changed the declaration of variables i & j in SHA1Update to
-unsigned long from unsigned int for the same reason.
-
-These changes should make no difference to any 32 bit implementations since
-an
-int and a long are the same size in those environments.
-
---
-I also corrected a few compiler warnings generated by Borland C.
-1. Added #include <process.h> for exit() prototype
-2. Removed unused variable 'j' in SHA1Final
-3. Changed exit(0) to return(0) at end of main.
-
-ALL changes I made can be located by searching for comments containing 'JHB'
------------------
-Modified 8/98
-By Steve Reid <sreid@sea-to-sky.net>
-Still 100% public domain
-
-1- Removed #include <process.h> and used return() instead of exit()
-2- Fixed overwriting of finalcount in SHA1Final() (discovered by Chris Hall)
-3- Changed email address from steve@edmweb.com to sreid@sea-to-sky.net
