Not ChangeLog entries, but commit log message formatted as ChangeLog.
IOW, this:

    Restore 'command-debug-status' functionality

    * src/callint.c (Fcall_interactively): Bind command-debug-status
    to nil.  This restores functionality inadvertently removed in
    Emacs 25.1.  (Bug#24555)

    * lisp/subr.el (command-debug-status): Declare obsolete.

    * doc/lispref/debugging.texi (Internals of Debugger): Document
    that 'command-debug-status' is obsolete.
