            GDB 8.2.1 released!

Release 8.2.1 of GDB, the GNU Debugger, is now available.  GDB is
a source-level debugger for Ada, C, C++, Go, Rust, and many other
languages.  GDB can target (i.e., debug programs running on)
more than a dozen different processor architectures, and GDB itself
can run on most popular GNU/Linux, Unix and Microsoft Windows variants.
GDB is free (libre) software.

You can download GDB from the GNU FTP server in the directory:
