+ add note in curs_util.3x about unctrl.h
+ review/improve header files to ensure that those include necessary
files except for the previously-documented cases (report by Isaac
Pascual Monells).
+ improved test-package scripts, adapted from byacc 1.9 20180525.
+ fix some gcc8 warnings seen in Redhat package build, but
work around bug in gcc8 compiler warnings in comp_parse.c
+ add deprecation warnings for internal functions called by older
versions of tack.
+ fix a special case in PutAttrChar() where a cell is marked as
alternate-character set, but the terminal does not actually support
the given graphic character. This would happen in an older terminal
such as vt52, which lacks most line-drawing capability.
+ 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.
+ modify several test programs to use new popup_msgs, adapted from
help-screen used in test/edit_field.c
+ drop two symbols obsoleted in 2004: _nc_check_termtype, and
_nc_resolve_uses
+ fix some old copyright dates (cf: 20031025).
+ build-fixes for test/savescreen.c to work with AIX and HPUX.
+ minor fix to configure script, adding a backslash/continuation.
+ extend TERMINAL structure for ABI 6 to store numbers internally as
integers rather than short, by adding new data for this purpose.
+ more fixes for minor memory-leaks in test-programs.
+ change logic in wins_nwstr() to avoid addressing data past the output
of mbstowcs().
+ correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
+ fix minor memory-leaks in test-programs.
+ further improve ifdef in term_entry.h for internal definitions not
used by tack.
+ change TERMINAL structure in term.h to make it opaque. Some
applications misuse its members, e.g., directly modifying it
rather than using def_prog_mode().
+ modify utility headers such as tic.h to make it clearer which are
externals that are used by tack.
+ improve curs_slk.3x in particular its discussion of portability.
+ fix cut/paste in legacy_encoding.3x
+ add prototype for find_pair() to new_pair.3x (report by Branden
Robinson).
+ fix a couple of broken links in generated man-html documentation.
+ regenerate man-html documentation.
+ add note in curs_addch.3x about line-drawing when it depends upon
UTF-8.
+ add tic -q option for consistency with infocmp, use it to suppress
all comments from the "tic -I" output.
+ modify infocmp -q option to suppress the "Reconstructed from"
header.
+ add infocmp/tic -Q option, which allows one to dump the compiled
form of the terminal entry, in hexadecimal or base64.
+ sort options in usage message for infocmp, to make it simpler to
see unused letters.
+ update usage message for tic, adding "-0" option.
+ documented differences in ESCDELAY versus AIX's implementation.
+ fix some compiler warnings from ports.
+ modify --with-pkg-config-libdir option to make it possible to install
".pc" files even if pkg-config is not found (adapted by patch by
Joshua Root).
+ modify mvcur() to distinguish between internal use by the ncurses
library, and external callers, preventing it from reading the content
of the screen which is only nonblank when curses calls have updated
it. This makes test/dots_mvcur.c avoid painting colored cells in
the left margin of the display.
+ minor fix to test/dots_mvcur.c
+ move configured symbols USE_DATABASE and USE_TERMCAP to term.h as
NCURSES_USE_DATABASE and NCURSES_USE_TERMCAP to allow consistent
use of these symbols in term_entry.h
+ correct initialization in knight.c which let it occasionally make
an incorrect move (cf: 20001028).
+ improve documentation of the terminfo/termcap search path.
+ minor tidying of terminfo.tail, clarify reason for limitation
regarding mapping of \0 to \200
+ minor improvement to _nc_copy_termtype(), using memcpy to replace
loops.
+ fix no-leaks checking in test/demo_termcap.c to account for multiple
calls to setupterm().
+ modified the libgpm change to show previous load as a problem in the
debug-trace.
> merge some patches from OpenSUSE rpm (Werner Fink):
+ ncurses-5.7-printw.dif, fixes for varargs handling in lib_printw.c
+ ncurses-5.7-gpm.dif, do not dlopen libgpm if already loaded by
runtime linker
+ ncurses-5.6-fallback.dif, do not free arrays and strings from static
fallback entries
+ moved static data from db_iterator.c to lib_data.c
+ modify db_iterator.c for memory-leak checking, fix one leak.
+ modify misc/gen-pkgconfig.in to use Requires.private for the parts
of ncurses rather than Requires, as well as Libs.private for the
other library dependencies (prompted by Debian #644728).
+ improve cleanup() function in lib_tstp.c, using _exit() rather than
exit() and checking for SIGTERM rather than SIGQUIT (prompted by
comments forwarded by Nicholas Marriott).
+ reduce name pollution from term.h, moving fallback #define's for
tcgetattr(), etc., to new private header nc_termios.h (report by
Sergio NNX).
+ two minor fixes for tracing (patch by Vassili Courzakis).
+ improve trace initialization by starting it in use_env() and
ripoffline().
+ review old email, add details for some changelog entries.
+ improve performance of tigetstr, etc., by using hashing code from tic.
+ minor fixes for memory-leak checking.
+ add test/demo_terminfo, for comparison with demo_termcap
+ continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).
This change finishes merging for menu and panel libraries, does
part of the form library.
+ add configure option --enable-weak-symbols to turn on new feature.
+ add configure-check for availability of weak symbols.
+ modify linkage with pthread library to use weak symbols so that
applications not linked to that library will not use the mutexes,
etc. This relies on gcc, and may be platform-specific (patch by Dr
Werner Fink).
+ add note to INSTALL to document limitation of renaming of tic library
using the --with-ticlib configure option (report by Dr Werner Fink).
+ document (in manpage) why tputs does not detect I/O errors (prompted
by comments by Samuel Thibault).
+ fix remaining warnings from Klocwork report.
