+
+20180804
+ + improve logic for clear with E3 extension, in case the terminal

+ + use configure --with-config-suffix option to work around filename
+ conflict with Debian packages versus test-packages.
+ + update tracemunch to work with perl 5.26.2, which changed the rules
+ for escaping regular expressions.

+
+20180407
+ + clarify in manual pages that vwprintw and vwscanw are obsolete,
+ not part of X/Open Curses since 2007.
+ + use "const" in some prototypes rather than NCURSES_CONST where X/Open
+ Curses was updated to do this, e.g., wscanw, newterm, the terminfo
+ interface. Also use "const" for consistency in the termcap
+ interface, which was withdrawn by X/Open Curses in Issue 5 (2007).
+ As of Issue 7, X/Open Curses still lacks "const" for certain return
+ values, e.g., keyname().
+
+20180331
+ + improve terminfo write/read by modifying the fourth item of the

+
+20180303
+ + modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
+ avoid expansion of "CUR" in trace.
+ + improve a few lintian warnings in test-packages.
+ + modify lib_setup to avoid calling pthread_self() without first
+ verifying that the address is valid, i.e., for weak symbols
+ (report/patch by Werner Fink).
+ + modify generated terminfo.5 to not use "expand" and related width
+ on the last column of tables, making layout on wide terminals look
+ better (adapted from patch by Kir Kolyshkin).
+ + add a category to report_offsets, e.g., "w" for wide-character, "t"
+ for threads to make the report more readable. Reorganized the
+ structures reported to make the categories more apparent.
+ + simplify some ifdef's for extended-colors.
+ + add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
+ how similar the different tinfo configurations are.
+
+20180224
+ + modify _nc_resolve_uses2() to detect incompatible types when merging
+ a "use=" clause of extended capabilities. The problem was seen in a

+ + add a null-pointer check in safe_sprintf.c (report by Steven Noonan).
+ + improve fix for Debian #882620 by reusing limit2 variable (report by
+ Julien Cristau, Sven Joachim).
+
+20180210
+ + modify misc/Makefile.in to install/uninstall explicit list in case
+ the build-directory happens to have no ".pc" files when an uninstall
+ is performed (report by Jeffrey Walton).
+ + deprecate safe-sprintf, since the vsnprintf function, which does what
+ was needed, was standardized long ago.
+ + add several development/experimental options to development packages.
+ + minor reordering of options in configure script to make the threaded
+ and reentrant options distinct from the other extensions which are
+ normally enabled.
+
+20180203
+ + minor fixes to test/*.h to make them idempotent.
+ + add/use test/parse_rgb.h to show how the "RGB" capability works.
