What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 5.2:
+*** Changes since GDB 5.3:
-* ``gdbserver'' now supports multithreaded applications on some targets
+* Default MI syntax changed to "mi2".
-Support for multithreaded applications using libthread_db has been
-added for arm*-*-linux*-gnu*, i[3456]86-*-linux*-gnu*,
-mips*-*-linux*-gnu*, powerpc*-*-linux*-gnu*, and sh*-*-linux*-gnu*.
+The default MI (machine interface) syntax, enabled by the command line
+option "-i=mi", has been changed to "mi2". The previous MI syntax,
+"mi1", can be enabled by sepcifying the option "-i=mi1".
+
+Support for the original "mi0" syntax (included in GDB 5.0) has been
+removed.
+
+Fix for gdb/192: removed extraneous space when displaying frame level.
+Fix for gdb/672: update changelist is now output in mi list format.
+Fix for gdb/702: a -var-assign that updates the value now shows up
+ in a subsequent -var-update.
+
+* OBSOLETE configurations and files
+
+Configurations that have been declared obsolete in this release have
+been commented out. Unless there is activity to revive these
+configurations, the next release of GDB will have their sources
+permanently REMOVED.

+OS/9000 i[34]86-*-os9k
+I960 with MON960 i960-*-coff
+
+* MIPS $fp behavior changed
+
+The convenience variable $fp, for the MIPS, now consistently returns
+the address of the current frame's base. Previously, depending on the
+context, $fp could refer to either $sp or the current frame's base
+address. See ``8.10 Registers'' in the manual ``Debugging with GDB:
+The GNU Source-Level Debugger''.
+
+*** Changes in GDB 5.3:
+
+* GNU/Linux shared library multi-threaded performance improved.
+
+When debugging a multi-threaded application on GNU/Linux, GDB now uses
+`/proc', in preference to `ptrace' for memory reads. This may result
+in an improvement in the start-up time of multi-threaded, shared
+library applications when run under GDB. One GDB user writes: ``loads
+shared libs like mad''.
+
+* ``gdbserver'' now supports multi-threaded applications on some targets
+
+Support for debugging multi-threaded applications which use
+the GNU/Linux LinuxThreads package has been added for
+arm*-*-linux*-gnu*, i[3456]86-*-linux*-gnu*, mips*-*-linux*-gnu*,
+powerpc*-*-linux*-gnu*, and sh*-*-linux*-gnu*.
* GDB now supports C/C++ preprocessor macros.

to a bfd-format or binary file (dump and append), and back
from a file into memory (restore).
+* Improved "next/step" support on multi-processor Alpha Tru64.
+
+The previous single-step mechanism could cause unpredictable problems,
+including the random appearance of SIGSEGV or SIGTRAP signals. The use
+of a software single-step mechanism prevents this.

*** Changes in GDB 5.2.1:
* New targets.
