christos 4559860ef2 May 11th, 2019: GDB 8.3 Released! 
The latest version of GDB, version 8.3, is available for
          download.

          This version of GDB includes the following changes and
          enhancements:

          + Support for new native configurations (also available as a
            target configuration):
               o RISC-V GNU/Linux (riscv*-*-linux*)
               o RISC-V FreeBSD (riscv*-*-freebsd*)
          + Support for new target configurations:
               o CSKY ELF (csky*-*-elf)
               o CSKY GNU/Linux (csky*-*-linux)
               o NXP S12Z ELF (s12z-*-elf)
               o OpenRISC GNU/Linux (or1k*-*-linux*)
          + Native Windows debugging is only supported on Windows XP or
            later.
          + The Python API in GDB now requires Python 2.6 or later.
          + GDB now supports terminal styling for the CLI and TUI. Source
            highlighting is also supported by building GDB with GNU
            Highlight.
          + Experimental support for compilation and injection of C++
            source code into the inferior (requires GCC 7.1 or higher,
            built with libcp1.so).
          + GDB and GDBserver now support IPv6 connections.
          + Target description support on RISC-V targets.
          + Various enhancements to several commands:
               o "frame", "select-frame" and "info frame" commands
               o "info functions", "info types", "info variables"
               o "info thread"
               o "info proc"
               o System call alias catchpoint support on FreeBSD
               o "target remote" support for Unix Domain sockets.
          + Support for displaying all files opened by a process

         + DWARF index cache: GDB can now automatically save indices of
            DWARF symbols on disk to speed up further loading of the same
            binaries.
          + Various GDB/MI enhancements.
          + GDBserver on PowerPC GNU/Linux now supports access to the PPR,
            DSCR, TAR, EBB/PMU, and HTM registers.
          + Ada task switching support when debugging programs built with
            the Ravenscar profile added to aarch64-elf.
          + GDB in batch mode now exits with status 1 if the last executed
            command failed.
          + Support for building GDB with GCC's Undefined Behavior
            Sanitizer.

          See the NEWS file for a more complete and detailed list of what
          this release includes.
