 *** Changes since GDB 12
 
+* "info breakpoints" now displays enabled breakpoint locations of
+  disabled breakpoints as in the "y-" state.  For example:

+* GDB now honours the DWARF prologue_end line-table entry flag the compiler can

+  past its prologue.
+
+* Python API
+
+  ** GDB will now reformat the doc string for gdb.Command and

+maintenance show ignore-prologue-end-flag
+  This setting, which is off by default, controls whether GDB ignores the
+  PROLOGUE-END flag from the line-table when skipping prologue.  This can be
+  used to force GDB to use prologue analyzers if the line-table is constructed
+  from erroneous debug information.
+
+* Changed commands
+
+maintenance info line-table
+  Add a PROLOGUE-END column to the output which indicates that an
+  entry corresponds to an address where a breakpoint should be placed
+  to be at the first instruction past a function's prologue.
