*** 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.
+
+* 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.
+
+* 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
* 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.
-* New configure options
+* 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
