+ expanded description of tgetstr's area pointer in manual page
(report by Todd M Lewis).
+ in-progress changes to modify test-packages to use ncursesw6 rather
than ncursesw, with updated configure scripts.
+ modify CF_NCURSES_CONFIG in Ada95- and test-configure scripts to

rpath option.

NOTE: as a side-effect, this renames
adacurses-config to adacurses5-config and
adacursesw-config to adacursesw5-config
+ modify debian/rules test package to suffix programs with "6".
+ clarify in curs_inopts.3x that window-specific settings do not

are only button-presses for buttons "4" and "5", so there is no need

screen-size of 24x80 in the non-buffered mode.
+ modify generated misc/Makefile to suppress install.data from the
dependencies if the --disable-db-install option is used, compensating
for the top-level makefile changes used to add ncurses*-config in the

because the parameters to be incremented were already on the internal
stack (report by Corinna Vinschen).
+ modify tic's "-c" option to take into account the "-C" option to
activate additional checks which compare the results from running
tparm() on the terminfo expressions versus the translated termcap
expressions.
+ modify tic to allow it to read from FIFOs (report by Matthieu Fronton,
cf: 20120324).

instead of <>.
+ samples/ncurses2-util.adb: removed unused with clause. The warning
was removed by an obsolete pragma.

was used in a case statement, values were tested by the Ada compiler
to be consecutive anyway.
+ src/Makefile.in: remove duplicate stanza
+ only consider using a project for shared libraries.

line split after "%;".
+ amend scripting for --with-cxx-shared option to handle the debug
library "libncurses++_g.a" (report by Sven Joachim).

local -I include options in case someone has set conflicting -I
options in $CPPFLAGS (prompted by patch for ncurses/Makefile.in by
Vassili Courzakis).

the RPATH_LIST variable, e.g., "../lib" as used in installing shared
libraries or executables.

starting with version 0.20 in 2009 -TD
+ improve CF_GCC_VERSION to work around Debian's customization of gcc

+ add cnorm/civis to wsvt25 entry from NetBSD CVS (report/analysis by
Onno van der Linden).
+ corrected 'op' for bterm (report by Samuel Thibault) -TD
+ modify test/background.c to demonstrate a background character
holding a colored ACS_HLINE. The behavior differs from SVr4 due to
the thick- and double-line extension (cf: 20091003).

of ordering and overrides -TD
+ add consistency check in tic for screen's "XT" capability.

+ fix an inconsistency between tic/infocmp "-x" option; tic omits all
non-standard capabilities, while infocmp was ignoring only the user
definable capabilities.
+ improve special case in tic parsing of description to allow it to be
followed by terminfo capabilities. Previously the description had to
be the last field on an input line to allow tic to distinguish
between termcap and terminfo format while still allowing commas to be
embedded in the description.
+ correct variable name in gen_edit.sh which broke configurability of
the --with-xterm-kbs option.
+ revert 2011-07-16 change to "linux" alias, return to "linux2.2" -TD

a column showing which entries belong to a given database.

caching improvements from 20111001 and 20111126.
+ correct generation of pc-files when ticlib or termlib options are
given to rename the corresponding tic- or tinfo-libraries (report
by Sven Joachim).
+ document a portability issue with tput, i.e., that scripts which work
with ncurses may fail in other implementations that do no parameter
analysis.
+ add putty-sco entry -TD
+ review/fix places in manpages where --program-prefix configure option
was not being used.
+ add -D option to infocmp, to show the database locations that it
could use.
+ fix build for the special case where term-driver, ticlib and termlib
are all enabled. The terminal driver depends on a few features in
the base ncurses library, so tic's dependencies include both ncurses
and termlib.
+ fix build work for term-driver when --enable-wgetch-events option is
enabled.
+ use <stdint.h> types to fix some questionable casts to void*.
+ modify configure script to check if thread library provides
pthread_mutexattr_settype(), e.g., not provided by Solaris 2.6
+ modify configure script to suppress check to define _XOPEN_SOURCE
for IRIX64, since its header files have a conflict versus
_SGI_SOURCE.

tinfo-libraries, which were omitted in recent change (cf: 20111126).
+ fix inconsistent checks on $PKG_CONFIG variable in configure script.

absolute pathname.

generate, rather than deriving the list from the libraries which have
been built (patch by Mike Frysinger).
+ use AC_CHECK_TOOLS in preference to AC_PATH_PROGS when searching for
ncurses*-config, e.g., in Ada95/configure and test/configure (adapted
from patch by Mike Frysinger).
+ add pccon entries for OpenBSD console (Alexei Malinin).
+ build-fix for OpenBSD 4.9 with gcc 4.2.1, setting _XOPEN_SOURCE to
600 to work around inconsistent ifdef'ing of wcstof between C and
C++ header files.
+ modify capconvert script to accept more than exact match on "xterm",
e.g., the "xterm-*" variants, to exclude from the conversion (patch
by Robert Millan).
+ add -lc_r as alternative for -lpthread, allows build of threaded code
in older FreeBSD machines.
+ build-fix for MirBSD, which fails when either _XOPEN_SOURCE or
_POSIX_SOURCE are defined.
+ fix a typo misc/Makefile.in, used in uninstalling pc-files.
+ moved static data from db_iterator.c to lib_data.c
+ modify db_iterator.c for memory-leak checking, fix one leak.

of ncurses rather than Requires, as well as Libs.private for the
other library dependencies (prompted by Debian #644728).
+ modify misc/gen_edit.sh to select a "linux" entry which works with
the current kernel rather than assuming it is always "linux3.0"
(cf: 20110716).
+ revert a change to getmouse() which had the undesirable side-effect
of suppressing button-release events (report by Damien Guibouret,
cf: 20100102).
+ add xterm+kbs fragment from xterm #272 -TD
+ add configure option --with-pkg-config-libdir to provide control over
the actual directory into which pc-files are installed, do not use
the pkg-config environment variables (discussion with Frederic L W
Meunier).
+ add link to mailing-list archive in announce.html.in, as done in
FAQ (prompted by question by Andrius Bentkus).
+ improve manpage install by adjusting the "#include" examples to
show the ncurses-subdirectory used when --disable-overwrite option
is used.
+ install an alias for "curses" to the ncurses manpage, tied to the
--with-curses-h configure option (suggested by Reuben Thomas).
+ add a check to ensure that termcap files which might have "^?" do
not use the terminfo interpretation as "\177".
+ minor cleanup of X-terminal emulator section of terminfo.src -TD
+ add terminator entry -TD
+ add simpleterm entry -TD
+ improve wattr_get macros by ensuring that if the window pointer is
null, then the attribute and color values returned will be zero
(cf: 20110528).
+ add substitution for $RPATH_LIST to misc/ncurses-config.in
+ improve performance of tic with hashed-database by caching the
database connection, using atexit() to cleanup.
+ modify treatment of 2-character aliases at the beginning of termcap
entries so they are not counted in use-resolution, since these are
guaranteed to be unique. Also ignore these aliases when reporting
the primary name of the entry (cf: 20040501)
+ double-check gn (generic) flag in terminal descriptions to
accommodate old/buggy termcap databases which misused that feature.
+ minor fixes to _nc_tgetent(), ensure buffer is initialized even on
error-return.
