* Noteworthy changes in release 2.4.15 (2020-11-05) [stable]
** Bug fixes
Ensure term.h matches [n]curses[w].h (fix#58880).
Fix a potential crash in the Lisp “interpreter”.
query-replace no longer prints the number of replacements on error.
** Build-related
Various improvements and fixes, including updates to gnulib and bootstrap,
improvements to the build instructions, and the removal of obsolete files.
Use automake’s parallel test harness to run the tests.
Make running the tests with Emacs optional. A lot of them do not pass any
more with recent Emacsen, but this is not an urgent problem.
Use ASAN instead of Valgrind for memory checking: this makes the tests run
much faster.
Remove the use of texinfo markup from docstrings.
tbl_vars.h no longer needs to be generated from tbl_vars.h.in, as no
substitutions were being made.
** Miscellaneous
Some code clean-up, including a simplification to the calling convention
for C functions that implement editor commands.
Update some docstrings to match Emacs 27.1.
