+
+        * lisp/startup.el (startup--load-user-init-file): Test the value

+
+        * lisp/gnus/nndoc.el (nndoc-possibly-change-buffer): If we're
+        reading an mbox file, it may contain messages that use
+        content-transfer-encoding 8bit, which means that we have to treat
+        the file as a sequence of byte (bug#42951).  This avoids
+        double-decoding -- once by Emacs when inserting the mbox into the
+        buffer, and once by Gnus when displaying the articles.

+
+        * doc/misc/widget.texi (Basic Types): The user options
+        widget-glyph-directory and widget-glyph-enable were renamed long ago
+        to widget-image-directory and widget-image-enable, but the manual
+        kept calling them by their old names.  Update the names.

+        * configure.ac: When building terminfo.o, define
+        TERMINFO_DEFINES_BC if the library defines BC etc.
+        * src/terminfo.c (UP, BC, PC): Define depending on

+        Revert "Fix incorrect handling of module runtime and environment pointers."
+
+        This reverts commit cdc632fbe6e149318147a98cccf1b7af191f2ce8.
+        Those changes are too significant and non-trivial to be
+        suitable for a release branch at this time.
+
+2021-02-03  Philipp Stephani  <phst@google.com>
+
+        Fix incorrect handling of module runtime and environment pointers.
+
+        We used to store module runtime and environment pointers in the static
+        lists Vmodule_runtimes and Vmodule_environments.  However, this is
+        incorrect because these objects have to be kept per-thread.  With this
+        naive approach, interleaving module function calls in separate threads
+        leads to environments being removed in the wrong order, which in turn
+        can cause local module values to be incorrectly garbage-collected.
+
+        Instead, turn Vmodule_runtimes and Vmodule_environments into
+        hashtables keyed by the thread objects.  The fix is relatively
+        localized and should therefore be safe enough for the release branch.
+
+        Module assertions now have to walk the pointer list for the current
+        thread, which is more correct since they now only find environments
+        for the current thread.
+
+        Also add a unit test that exemplifies the problem.  It interleaves two
+        module calls in two threads so that the first call ends while the
+        second one is still active.  Without this change, this test triggers
+        an assertion failure.

+
+        Fix cond jump table compilation (bug#42919)
+
+        This bug affected compilation of
+
+         (cond ((member '(some list) variable) ...) ...)
+
+        While equal is symmetric, member is not; in the latter case the
+        arguments must be a variable and a constant list, in that order.
+
+        Reported by Ikumi Keita.
+
+        * lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
+        Don't treat equality and member predicates in the same way; only
+        the former are symmetric in their arguments.
+        * test/lisp/emacs-lisp/bytecomp-tests.el
+        (byte-opt-testsuite-arith-data): Add test cases.

+        Let Emacs start even if curdir is inaccessible
+
+        * lisp/startup.el (normal-top-level): Also delete PWD if
+        file-attributes fails for either $PWD or default-directory,
+        instead of failing out of the top level.
+        This fixes a regression from Emacs 26 (Bug#42903).

+        Prevent from frozen frame after `C-z' in Lucid builds
+
+        Some WMs (e.g. mutter in Gnome Shell) don't unmap iconized windows,
+        thus we won't get a MapNotify when deconifying them.
+        Check if we are deconifying a window elsewhere (Bug#42655).
