- Patch #353 - 2020/02/01
- amend change in patch #352 for button-events to fix a case where some followup events were not processed soon enough (report/patch by Jimmy Aguilar Mena).
- handle MappingNotify X event, to improve recovery when switching keyboard configurations using xkbcomp (prompted by discussion with Frank Mosch, Debian #661295). There is more work needed here, possibly in the X libraries.
- improve discussion of mouse-mode in ctlseqs.ms (suggested by Igor van den Hoven).
- further improve checks for Xft max-advance-width to take into account fonts which use two cells for ambiguous width characters. Also improve the time used for these checks (reports by Yuri Pankov, Frank Mosch).
- fix a few spelling errors reported by codespell (report by Jens Schleusener).
- modify run-tic.sh to prefer development version of ncurses since changes to terminfo file in patch #345 rely upon bug-fixes in ncurses (prompted by discussion with Will Senn).
- Patch #352 - 2020/01/16
- adjust fontsize data to handle a minor inconsistency from recent Xft versions (Debian #880407, adapted from patch by Vincent Lefevre).
- add a table to the manual page description of forceBoxChars to alert the reader to the special characters aside from “line-drawing” which are drawn directly when this resource is set (Debian #931305).
- improve checkXft logic which attempts to detect fonts whose max-advance-width is inconsistent with the actual glyph widths. For some fonts, it is necessary to check additional characters (report/analysis by Jan Engelhardt).
- improve configure-checks for X headers and libraries on recent MacOS, which has moved those files under /usr/X11.
- improve portability of iconify/deiconify feature by taking into account some window managers which manipulate the EWMH _NET_WM_STATE property, adding/removing _NET_WM_STATE_HIDDEN rather than actually minimizing the window (prompted by discussion with Jörg Breitbart).
- improve workaround from patch #287 for the -iconic option when configured with toolbar by postponing the extra request for minimizing the window to the end of menu-initialization.
- modify xevents special-case for mouse-events to include button-events so that the meta key by itself can generate button-events (report/analysis by Mattias Engdegård).
- amend SGR-stack change from patch #348 to not associate bold attribute with background color (report by Nicholas Marriott).
- fix copy/paste error in manual page (patch by Larry Hynes).
- add definitions in xterm_io.h so that GNU/Hurd will use posix_openpty (patch by Samuel Thibault).
- build-fix in debug-tracing, for esctest.
- updated autoconf macros
- update config.guess
- Patch #351 - 2019/11/17
- correct logic in property_to_string for deciding when to fallback from UTF-8 decoding to ISO-8859-1 decoding, broken in xterm #350 (FreeBSD #241961).
- add -report-icons to help-message.
- improved autoconf macros:
- CF_ADD_LIBS: the change to filter out duplicates caused this to append rather than prepend. revise to fix that.
- CF_GCC_VERSION and CF_GCC_WARNINGS: move checks to distinguish icc/clang from gcc from the macro which handles the --enable-warnings option, to make this work without-warnings for the inline-checks.
- update config.guess, config.sub
- correct status in XTGETXRES replies when the resource was not found.
- fix some gcc, cppcheck, clang and coverity warnings.
