*** Changes since GDB 6.0:
+* Removed --with-mmalloc
+
+Support for the mmalloc memory manager has been removed, as it
+conflicted with the internal gdb byte cache.
+
+* Changes in AMD64 configurations
+
+The AMD64 target now includes the %cs and %ss registers. As a result
+the AMD64 remote protocol has changed; this affects the floating-point
+and SSE registers. If you rely on those registers for your debugging,
+you should upgrade gdbserver on the remote side.
+
+* Revised SPARC target
+
+The SPARC target has been completely revised, incorporating the
+FreeBSD/sparc64 support that was added for GDB 6.0. As a result
+support for LynxOS and SunOS 4 has been dropped. Calling functions
+from within GDB on operating systems with a non-executable stack
+(Solaris, OpenBSD) now works.
+
+* New C++ demangler
+
+GDB has a new C++ demangler which does a better job on the mangled
+names generated by current versions of g++. It also runs faster, so
+with this and other changes gdb should now start faster on large C++
+programs.
+
+* DWARF 2 Location Expressions
+
+GDB support for location expressions has been extended to support function
+arguments and frame bases. Older versions of GDB could crash when they
+encountered these.
+
+* New native configurations
+
+NetBSD/amd64 x86_64-*-netbsd*
+OpenBSD/sparc sparc-*-openbsd*
+OpenBSD/sparc64 sparc64-*-openbsd*
+
+* New debugging protocols
+
+M32R with SDI protocol m32r-*-elf*
+
+* "set prompt-escape-char" command deleted.
+
+The command "set prompt-escape-char" has been deleted. This command,
+and its very obscure effet on GDB's prompt, was never documented,
+tested, nor mentioned in the NEWS file.
+
+* 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.

+*** Changes in GDB 6.0:
+
+* Objective-C
+
+Support for debugging the Objective-C programming language has been
+integrated into GDB.
+
+* New backtrace mechanism (includes DWARF 2 Call Frame Information).
+
+DWARF 2's Call Frame Information makes available compiler generated
+information that more exactly describes the program's run-time stack.
+By using this information, GDB is able to provide more robust stack
+backtraces.
+
+The i386, amd64 (nee, x86-64), Alpha, m68hc11, ia64, and m32r targets
+have been updated to use a new backtrace mechanism which includes
+DWARF 2 CFI support.
+
+* Hosted file I/O.
+
+GDB's remote protocol has been extended to include support for hosted
+file I/O (where the remote target uses GDB's file system). See GDB's
+remote protocol documentation for details.
+
+* All targets using the new architecture framework.
+
+All of GDB's targets have been updated to use the new internal
+architecture framework. The way is now open for future GDB releases
+to include cross-architecture native debugging support (i386 on amd64,
+ppc32 on ppc64).
+
+* GNU/Linux's Thread Local Storage (TLS)
+
+GDB now includes support for for the GNU/Linux implementation of
+per-thread variables.
+
+* GNU/Linux's Native POSIX Thread Library (NPTL)
+
+GDB's thread code has been updated to work with either the new
+GNU/Linux NPTL thread library or the older "LinuxThreads" library.
+
+* Separate debug info.
+
+GDB, in conjunction with BINUTILS, now supports a mechanism for
+automatically loading debug information from a separate file. Instead
+of shipping full debug and non-debug versions of system libraries,
+system integrators can now instead ship just the stripped libraries
+and optional debug files.
+
+* DWARF 2 Location Expressions
+
+DWARF 2 Location Expressions allow the compiler to more completely
+describe the location of variables (even in optimized code) to the
+debugger.
+
+GDB now includes preliminary support for location expressions (support
+for DW_OP_piece is still missing).
+
+* Java
+
+A number of long standing bugs that caused GDB to die while starting a
+Java application have been fixed. GDB's Java support is now
+considered "useable".
+
+* GNU/Linux support for fork, vfork, and exec.
+
+The "catch fork", "catch exec", "catch vfork", and "set follow-fork-mode"
+commands are now implemented for GNU/Linux. They require a 2.5.x or later
+kernel.
+
* GDB supports logging output to a file
There are two new commands, "set logging" and "show logging", which can be
used to capture GDB's output to a file.
-*** Changes in GDB 6.0:
-
* The meaning of "detach" has changed for gdbserver
The "detach" command will now resume the application, as documented. To
disconnect from gdbserver and leave it stopped, use the new "disconnect"
command.
-* d10v `regs' command deprecated
+* d10v, m68hc11 `regs' command deprecated
The `info registers' command has been updated so that it displays the
registers using a format identical to the old `regs' command.
Fix for gdb/702: a -var-assign that updates the value now shows up
in a subsequent -var-update.
+* New native configurations.
+
+FreeBSD/amd64 x86_64-*-freebsd*
+
* Multi-arched targets.
