+2019-08-03  Colin Watson  <cjwatson@debian.org>
+
+	* Version: 2.8.6.
+
+2019-08-03  Colin Watson  <cjwatson@debian.org>
+
+	Update syscall lists from systemd bca5a0eacc
+
+	* lib/sandbox.c (make_seccomp_filter): Add rseq (see
+	https://github.com/systemd/systemd/issues/12127).
+
+2019-05-02  Colin Watson  <cjwatson@debian.org>
+
+	Improve manual build portability slightly
+
+	* manual/Makefile.am ($(MANUAL).pp, .pp.dvi, .pp.ps, .pp.tdvi,
+	.tdvi.tps, .pp.cat, .pp.html): Use "mv -f" rather than just "mv", since
+	Automake seems to prefer that for its own rules.
+
+2019-05-02  Colin Watson  <cjwatson@debian.org>
+
+	Make manual build more robust against failures
+
+	Fixes Savannah bug #56254.
+
+	* manual/Makefile.am ($(MANUAL).pp, .pp.dvi, .pp.ps, .pp.tdvi,
+	.tdvi.tps, .pp.cat, .pp.html): Write output to *.new files and rename
+	into place, so that failures are properly retried in future runs.
+
+2019-03-03  Colin Watson  <cjwatson@debian.org>
+
+	Avoid configure error message if nroff is broken
+
+	* m4/man-gnu-nroff.m4 (MAN_PROG_GNU_NROFF): Adjust test arguments
+	slightly to avoid a spurious error message if nroff is sufficiently
+	broken that it doesn't produce numeric output for "\n(.g".
+
+2019-03-03  Colin Watson  <cjwatson@debian.org>
+
+	Fix warnings when configuring --without-libseccomp
+
+	* lib/sandbox.c (_sandbox_load): Mark sandbox and permissive parameters
+	unused when HAVE_LIBSECCOMP is undefined, to avoid warnings from "gcc
+	-Wunused-parameter".
+
+2019-03-03  Colin Watson  <cjwatson@debian.org>
+
+	Add configure option to disable building manual
+
+	* m4/man-arg-manual.m4: New file.
+	* configure.ac: Add MAN_ARG_MANUAL.
+	* manual/Makefile.am: Perform most rules only if BUILD_MANUAL is true.
+	* manual/intro.me (Arguments to configure): Add --disable-manual.
+	* README (Non-generic arguments to configure): Update.
+	* NEWS: Document this.
+
+2019-03-03  Colin Watson  <cjwatson@debian.org>
+
+	* NEWS: Document container type changes.
+
+2019-02-05  Colin Watson  <cjwatson@debian.org>
+
+	Add some missing entries to lib/README
+
+	* lib/README: Add glcontainers.*, orderfiles.*, and sandbox.*.
+
+2019-02-05  Colin Watson  <cjwatson@debian.org>
+
+	Remove pipeline.* from lib/README
+
+	It's been a separate library since 2010.
+
+	* lib/README: Remove pipeline.*.
+
+2019-02-05  Colin Watson  <cjwatson@debian.org>
+
+	Inline lower into name_to_key
+
+	With only one remaining user, it wasn't pulling its weight.
+
+	* libdb/db_lookup.c (name_to_key): Inline the implementation of lower.
+	* lib/Makefile.am (libman_la_SOURCES): Remove lower.c and lower.h.
+	* lib/README: Remove lower.*.
+	* lib/lower.c, lib/lower.h: Remove.
+
+2019-02-05  Colin Watson  <cjwatson@debian.org>
+
+	Simplify case-insensitivity in word_fnmatch
+
+	Using FNM_CASEFOLD saves us from having to lower-case the pattern
+	manually, and it also fixes the behaviour of "apropos -w" when given a
+	non-lower-case pattern.
+
+	* lib/wordfnmatch.c (word_fnmatch): Use isalpha and FNM_CASEFOLD rather
+	than manually lower-casing string or expecting pattern to have already
+	been lower-cased.
+	* NEWS: Document this.
+
+2019-02-05  Colin Watson  <cjwatson@debian.org>
+
+	Simplify case-insensitive comparisons in whatis
+
+	We can just use strcasecmp and similar functions rather than
+	lower-casing comparands manually.
+
+	In some corner cases this may result in matches that would not
+	previously have been returned (e.g. "whatis -w" with a non-lower-case
+	pattern).
+
+	* src/whatis.c (parse_name): Use strcasecmp and FNM_CASEFOLD rather than
+	manually lower-casing dbname or expecting pages to have already been
+	lower-cased.
+	(match): Use strcasestr and isalpha rather than manually lower-casing
+	whatis or expecting page to have already been lower-cased.
+	(parse_whatis): Remove lowpages parameter; pass pages directly to match
+	instead.
+	(do_apropos): Remove lowpages; parse_name and parse_whatis no longer
+	need it.
+
+2019-02-04  Colin Watson  <cjwatson@debian.org>
+
+	Import Gnulib's strcase module
+
+	We're already using strcasecmp and strncasecmp.
+
+	* bootstrap.conf (gnulib_modules): Add strcase.
+
+2019-02-04  Colin Watson  <cjwatson@debian.org>
+
+	Add missing #include
+
+	* src/straycats.c: Include <stdbool.h>.

+
+	Port roff_warnings to gl_list
+
+	* src/man.c (struct string_llist): Remove.
+	(parse_opt, make_roff_command): Convert roff_warnings to gl_list.
+	(main): Initialise roff_warnings.
+
+2019-02-04  Colin Watson  <cjwatson@debian.org>
+
+	Port parse_descriptions to gl_list
+
+	* src/descriptions.c (free_descriptions): Rename to ...
+	(page_description_free): ... this.  Adjust for gl_list's expected
+	interface.

+
+	Improve sandbox_free
+
+	* lib/sandbox.c (sandbox_free): Free sandbox->permissive_ctx too.

+
+2019-02-04  Colin Watson  <cjwatson@debian.org>
+
+	Port dblookup to gl_list
+
+	* libdb/db_lookup.c (free_mandata_struct): Only free a single structure,
+	rather than following list pointers.
+	(split_content): Stop initialising pinfo->next.
+	(dblookup, dblookup_pattern): Convert to gl_list.  Return a zero-length
+	list to indicate no matches, where previously we returned NULL.
+	(dblookup_exact): Adjust for changes in dblookup.  This function

+	* src/man.c (db_map_value_free): New function.
+	(try_db): Convert dblookup_pattern/dblookup_all cache to store gl_lists

+	means no matches in an existing database, rather than vice versa.
+	* src/whatis.c (do_whatis_section): Convert to gl_list.
+
+2019-02-03  Colin Watson  <cjwatson@debian.org>

+
+2019-02-03  Colin Watson  <cjwatson@debian.org>
+
+	Replace hashtable with Gnulib containers
+
+	Since we're using Gnulib's container types anyway, we might as well

+
+	Also remove lib/xchown.*; with only one call site, they don't pull their
+	weight over equivalent inline code.
+
+	* bootstrap.conf (gnulib_modules): Add lchown.
+	* configure.ac (AC_CHECK_FUNCS): Remove check for lchown.
+	* lib/Makefile.am (libman_la_SOURCES): Remove xchown.c and xchown.h.
+	* src/check_mandirs.c (chown_if_possible): Always use lchown rather than
+	chown, and inline the error check.
+
+	* po/POTFILES.in: Remove lib/xchown.c.
+	* po/man-db.pot, po/*.po: Update.

+
+	* bootstrap.conf (gnulib_modules): Add fcntl.
+	* configure.ac (AC_CHECK_HEADERS): Remove check for fcntl.h.

+	<fcntl.h> unconditionally.
+	* src/man.c: Remove conditional definitions of R_OK and X_OK; Gnulib's
+	<unistd.h> handles these.

+
+2019-01-26  Colin Watson  <cjwatson@debian.org>
+
+	Use bool type where appropriate
+
+	Now that we're using <stdbool.h> anyway due to gl_list (with Gnulib
+	providing <stdbool.h> if necessary), it makes sense to use it for our
+	own functions that have essentially boolean semantics.
+
+	* lib/encodings.c (compatible_encodings, is_roff_device): Return bool.

+
+	* docs/HACKING (Facilities and portability): Note that C99 runtime
+	facilities that are provided by Gnulib are OK.

+
+	Automatically add more man directories to manpath
+
+	Will Starms reported that, if both ../man and ../share/man directories
+	(for example) exist relative to a directory on $PATH, then only the
+	first was considered.
+
+	* src/manp.c (has_mandir): Rename to ...
+	(add_man_subdirs): ... this.  Insert directories as they are found
+	rather than returning them, and continue even if some have been found.
