-    is or should be arch-qualified. Closes: #776072
-  * Fix and update Arch substvar description in deb-substvars(5).
-  * Document that current build flag feature areas only work on Debian and
-    derivatives in dpkg-buildflags(1).
-  * Use “wildcard characters” instead of “wildchars” in dpkg-query(1).
   * Only trim trailing “/” and “/.” from «dpkg-query --search» arguments if
     they are a pathname, and not a pattern or a substring match.

-  * Document postinst “triggered” argument in debian/dpkg.postinst comment
-    header.

-  * Remove trailing newline from string literal in warning calls.
-  * Test suite:
-    - Check perl code compilation, warnings and strictness.
-  * Assume in Dpkg::Arch that the abitable is always present, and bump
-    libdpkg-perl Depends on dpkg to 1.16.3, the version introducing the file.
-  * Remove support for GCC_TARGET environment variable from Dpkg::Shlibs.
-    This was a temporary workaround for very old gcc toolchains. See #453267.
-  * Prefer multiarch paths to multilib ones in Dpkg::Shlibs.
-    Thanks to Helmut Grohne <helmut@subdivi.de>. Closes: #772184

-    Digest modules. Obsolete the 'program' property, and add a 'name' one.
   * Rework the Installed-Size field default value computation to make it
     reproducible regardless of the build system filesystem, and document
     how the value is computed and that it is just an approximation.
     Closes: #650077
-  * Fix support for cross-building dpkg:
-    - Assume a working C99 snprintf on SUS >= v3.
-    - Do not try to run the va_copy configure check, just check that the
-      symbol is available.
   * Use strftime() instead of «date -R» in dpkg-genchanges, as the latter
     is not specified by POSIX and is not widely portable.
   * Warn on obsolete '<' and '>' operators in dpkg --compare-versions.
-  * Document the obsolete --compare-versions '<' and '>' operators in the
-    dpkg(1) man page. Thanks to Tomas Pospisek <tpo_hp@sourcepole.ch>.
