+* sd-bus: introduce sd_bus_creds object and attach it to messages as well as allow querying it for names
+
+* sd-bus: support "const" properties as flag
+
+* sd-event: when a handler returns an error, just turn off its event
+ source, but do not return anything up to the event loop
+ caller. Instead add parameter to sd_event_request_quit() to take
+ retval. This way errors rippling upwards are the option, not the
+ default
+
+* sd-event: child pid handling: first invoke waitid(WNOHANG) and call event handler, only afterwards reap the process
+
+* sd-event: native support for watchdog stuff
+
+* machined, localed: when we try to kill an empty cgroup, generate an ESRCH call over the bus
+
+* sd-bus: SD_BUS_COMMENT() macro for inclusion in vtables, syntax inspired by gdbus
+
+* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
+
+* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
