                What has changed in GDB?
             (Organized release by release)

+*** Changes since GDB 6.2:
+
+*** Changes in GDB 6.2.1:
+
+* MIPS `break main; run' gave an heuristic-fence-post warning
+
+When attempting to run even a simple program, a warning about
+heuristic-fence-post being hit would be reported.  This problem has
+been fixed.
+
+* MIPS IRIX 'long double' crashed GDB
+
+When examining a long double variable, GDB would get a segmentation
+fault.  The crash has been fixed (but GDB 6.2 cannot correctly examine
+IRIX long double values).
+
+* VAX and "next"
+
+A bug in the VAX stack code was causing problems with the "next"
+command.  This problem has been fixed.
+
+*** Changes in GDB 6.2:
+
+* Fix for ``many threads''
+
+On GNU/Linux systems that use the NPTL threads library, a program
+rapidly creating and deleting threads would confuse GDB leading to the
+error message:
+
+       ptrace: No such process.
+       thread_db_get_info: cannot get thread info: generic error
+
+This problem has been fixed.
+
+* "-async" and "-noasync" options removed.
+
+Support for the broken "-noasync" option has been removed (it caused
+GDB to dump core).
 
 * New ``start'' command.
 
 This command runs the program until the begining of the main procedure.
 
+* New BSD Kernel Data Access Library (libkvm) interface
+
+Using ``target kvm'' it is now possible to debug kernel core dumps and
+live kernel memory images on various FreeBSD, NetBSD and OpenBSD
+platforms.  Currently supported (native-only) configurations are:
+
+FreeBSD/amd64                  x86_64-*-freebsd*

 * Signal trampoline code overhauled
 
 Many generic problems with GDB's signal handling code have been fixed.

+* END-OF-LIFE frame compatibility module
+
+GDB's internal frame infrastructure has been completely rewritten.
+The new infrastructure making it possible to support key new features
+including DWARF 2 Call Frame Information.  To aid in the task of
+migrating old configurations to this new infrastructure, a
+compatibility module, that allowed old configurations to continue to
+work, was also included.
+
+GDB 6.2 will be the last release to include this frame compatibility
+module.  This change directly impacts the following configurations:
+
+h8300-*-*
+mcore-*-*
+mn10300-*-*
+ns32k-*-*
+sh64-*-*
+v850-*-*
+xstormy16-*-*
+
+Unless there is activity to revive these configurations, they will be
+made OBSOLETE in GDB 6.3, and REMOVED from GDB 6.4.
