*** Changes since GDB 13
+* GDB now recognizes the NO_COLOR environment variable and disables
+ styling according to the spec. See https://no-color.org/.
+ Styling can be re-enabled with "set style enabled on".
+
* The AArch64 'org.gnu.gdb.aarch64.pauth' Pointer Authentication feature string
has been deprecated in favor of the 'org.gnu.gdb.aarch64.pauth_v2' feature
string.
