What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 8.1
+*** Changes since GDB 8.2
+
+* GDB now has experimental support for the compilation and injection of
+ C++ source code into the inferior. This beta release does not include
+ support for several language features, such as templates, constructors,
+ and operators.
+
+ This feature requires GCC 7.1 or higher built with libcp1.so
+ (the C++ plug-in).
+
+* GDB and GDBserver now support IPv6 connections. IPv6 addresses
+ can be passed using the '[ADDRESS]:PORT' notation, or the regular
+ 'ADDRESS:PORT' method.
+
+* DWARF index cache: GDB can now automatically save indices of DWARF
+ symbols on disk to speed up further loading of the same binaries.
+
+* GDB in batch mode now exits with status 1 if the last command to be
+ executed failed.
+
+* Changes to the "frame", "select-frame", and "info frame" CLI
+ commands. These commands all now take a frame specification which
+ is either a frame level, or one of the keywords 'level', 'address',
+ 'function', or 'view' followed by a parameter. Selecting a frame by
+ address, or viewing a frame outside the current backtrace now
+ requires the use of a keyword. Selecting a frame by level is
+ unchanged. The MI comment "-stack-select-frame" is unchanged.
+
+* New commands
+
+set debug compile-cplus-types
+show debug compile-cplus-types
+ Control the display of debug output about type conversion in the
+ C++ compile feature. Commands have no effect while compiliong
+ for other languages.
+
+set debug skip
+show debug skip
+ Control whether debug output about files/functions skipping is
+ displayed.
+
+frame apply [all | COUNT | -COUNT | level LEVEL...] [FLAG]... COMMAND
+ Apply a command to some frames.
+ FLAG arguments allow to control what output to produce and how to handle
+ errors raised when applying COMMAND to a frame.
+
+taas COMMAND
+ Apply a command to all threads (ignoring errors and empty output).
+ Shortcut for 'thread apply all -s COMMAND'.
+
+faas COMMAND
+ Apply a command to all frames (ignoring errors and empty output).
+ Shortcut for 'frame apply all -s COMMAND'.
+
+tfaas COMMAND
+ Apply a command to all frames of all threads (ignoring errors and empty
+ output).
+ Shortcut for 'thread apply all -s frame apply all -s COMMAND'.
+
+maint set dwarf unwinders (on|off)
+maint show dwarf unwinders
+ Control whether DWARF unwinders can be used.
+
+info proc files
+ Display a list of open files for a process.
+
+* Changed commands
+
+thread apply [all | COUNT | -COUNT] [FLAG]... COMMAND
+ The 'thread apply' command accepts new FLAG arguments.
+ FLAG arguments allow to control what output to produce and how to handle
+ errors raised when applying COMMAND to a thread.
+
+* MI changes
+
+ ** The '-data-disassemble' MI command now accepts an '-a' option to
+ disassemble the whole function surrounding the given program
+ counter value or function name. Support for this feature can be
+ verified by using the "-list-features" command, which should
+ contain "data-disassemble-a-option".
+
+ ** Command responses and notifications that include a frame now include
+ the frame's architecture in a new "arch" attribute.
+
+* New native configurations
+
+GNU/Linux/RISC-V riscv*-*-linux*
+
+* New targets
+
+GNU/Linux/RISC-V riscv*-*-linux*
+CSKY ELF csky*-*-elf
+CSKY GNU/LINUX csky*-*-linux
+
+* Python API
+
+ ** The gdb.Inferior type has a new 'progspace' property, which is the program
+ space associated to that inferior.
+
+ ** The gdb.Progspace type has a new 'objfiles' method, which returns the list
+ of objfiles associated to that program space.
+
+*** Changes in GDB 8.2
+
+* The 'set disassembler-options' command now supports specifying options
+ for the MIPS target.
* The 'symbol-file' command now accepts an '-o' option to add a relative
offset to all sections.
+* Similarly, the 'add-symbol-file' command also accepts an '-o' option to add
+ a relative offset to all sections, but it allows to override the load
+ address of individual sections using '-s'.
+
+* The 'add-symbol-file' command no longer requires the second argument
+ (address of the text section).
+
* The endianness used with the 'set endian auto' mode in the absence of
an executable selected for debugging is now the last endianness chosen
either by one of the 'set endian big' and 'set endian little' commands
* C expressions can now use _Alignof, and C++ expressions can now use
alignof.
+* Support for SVE on AArch64 Linux. Note that GDB does not detect changes to
+ the vector length while the process is running.
+
* New commands
set debug fbsd-nat
the tradeoff that there is a possibility of false hits being
reported.
+* Configure changes
+
+--enable-codesign=CERT
+ This can be used to invoke "codesign -s CERT" after building gdb.
+ This option is useful on macOS, where code signing is required for
+ gdb to work properly.
+
+--disable-gdbcli has been removed
+ This is now silently accepted, but does nothing.
+
*** Changes in GDB 8.1
* GDB now supports dynamically creating arbitrary register groups specified
