This is a log of changes that ncurses has gone through since Zeyd started
Changes through 1.9.9e did not credit all contributions;
it is not possible to add this information.
+20210116
+ + add comment for linux2.6 regarding CONFIG_CONSOLE_TRANSLATIONS
+ (report by Patrick McDermott) -TD
+ + make opts extension for getcchar work as documented for ncurses 6.1,
+ adding "-g" flag to test/demo_new_pair to illustrate.
+
+20210109
+ + fix errata in man/ncurses.3x from recent updates.

+ autoconf 2.52.20210105
+
+20210102
+ + update man/curs_memleaks.3x, to include <term.h> which declares
+ exit_terminfo.
+ + clarify man/curs_terminfo.3x, to mention why the macro setterm is
+ defined in <curses.h>, and remove it from the list of prototypes
+ (prompted by patch by Graeme McCutcheon).
+ + amend man/curs_terminfo.3x, to note that <curses.h> is required
+ for certain functions, e.g., those using chtype or attr_t for
+ types, as well as mvcur (cf: 20201031).
+ + use parameter-names in prototypes in curs_sp_funcs.3x, for
+ consistency with other manpages.

+ the middle of strings such as flash when the application uses
+ low-level calls rather than curses (cf: 20161217).
+ + modify configure check for c89/c99 aliases of clang to use its
+ -std option instead, because some platforms, in particular macOS,
+ do not provide workable c89/c99 aliases.
+
+20201121
+ + fix some compiler-warnings in experimental Windows-10 driver.
+ + add the definitions needed in recent configure-check for clang

+ with Reuben Thomas).
+ + improve format of output in tic's check_infotocap() function, to

+ + fix a potential indexing error in _nc_parse_entry(), seen with
+ Herlim's test data using address-sanitizer.

+ needed in to tic's use-resolution when pad_char is cancelled
+ (report/testcase by Robert Sebastian Herlim)

+ (discussion with Keith Marshall).
+ + other build-fixes for Ada95 with MinGW.

+
+20200613
+ + update list of functions in ncurses.3x
+ + move dlclose() call from lib_mouse.c to delscreen() to avoid a case
+ in the former which could be called from SIGTSTP handler (Debian
+ #961097).

+ (report/testcase by "puppet-meteor").
+ + add a check for end-of-string in cvtchar to handle a malformed
+ string in infotocap (report/testcase by "puppet-meteor").
