It's about time we had a new stable branch, and if I wait any longer for
people to review more patches it'll be too late for Debian 7. So, here's
D-Bus 1.6:


The “soul of this machine has improved” release.

This version starts a new stable branch of D-Bus: only bug fixes will
be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.

Summary of changes since 1.4.x:

• New requirements
  · compiler support for 64-bit integers (int64_t or equivalent)

• D-Bus Specification v0.19

• New dbus-daemon features
  · <allow own_prefix="com.example.Service"/> rules allow the service to
    own names like com.example.Service.Instance3
  · optional systemd integration when checking at_console policies
  · --nopidfile option, mainly for use by systemd
  · path_namespace and arg0namespace may appear in match rules
  · eavesdropping is disabled unless the match rule contains

• New public API
  · functions to validate various string types (dbus_validate_path()
  · dbus_type_is_valid()
  · DBusBasicValue, a union of every basic type

• Bug fixes
  · removed an unsafe reimplementation of recursive mutexes
  · dbus-daemon no longer busy-loops if it has far too many file
  · dbus-daemon.exe --print-address works on Windows
  · all the other bug fixes from 1.4.20

• Other major implementation changes
  · on Linux, dbus-daemon uses epoll if supported, for better
  · dbus_threads_init() ignores its argument and behaves like
    dbus_threads_init_default() instead
  · removed the per-connection link cache, improving dbus-daemon

• Developer features
  · optional Valgrind instrumentation (--with-valgrind)
  · optional Stats interface on the dbus-daemon (--enable-stats)
  · optionally abort whenever malloc() fails (--enable-embedded-tests
    and export DBUS_MALLOC_CANNOT_FAIL=1)

Changes since 1.5.12:

• Be more careful about monotonic time vs. real time, fixing
  DBUS_COOKIE_SHA1 spec-compliance (fd.o #48580, David Zeuthen)

• Don't use install(1) within the source/build trees, fixing the build
  as non-root when using OpenBSD install(1) (fd.o #48217, Antoine

• Add missing commas in some tcp and nonce-tcp addresses, and remove
  an unused duplicate copy of the nonce-tcp transport in Windows builds
  (fd.o #45896, Simon McVittie)
