1 Overview of changes in lightdm 1.19.3
3 * Fix in-session greeters not working for greeter logins
5 Overview of changes in lightdm 1.19.2
7 * Add support for greeters running inside sessions. This is enabled by
8 setting X-LightDM-Allow-Greeter inside the session .desktop file.
9 The session can then use liblightdm to connect one greeter to the
10 daemon. The communication is done using a socket
11 (/var/run/lightdm/<user>/greeter-socket) that is accessible to any
12 process run by that user. Consider controlling access to this socket
13 using a MAC system such as AppArmor.
14 * Report errors for all liblightdm methods. This will require existing
15 greeters to update their API usage. The ABI is unchanged.

26 socket to sessions. This used to work but no longer works in Mir 0.21

29 * Use only a single compositor on local seats
30 * Fix Mir greeter log filename having "(null)" in the name

83 LC_IDENTIFICATION variables to the list of inherited locale variables.
84 * Implement XDMCP ForwardQuery.
85 * Fix small memory leak in XDMCP logging code.
87 Overview of changes in lightdm 1.17.0

90 * Support using libaudit to generate audit events.
91 * Handle trailing whitespace on boolean values in configuration.
92 * Update example configuration to more correctly match allowed options.
93 * Fix unnecessary X server from being launched when locking seats.

117 fixes some small bugs in both the Vala and GIR bindings.
118 * Don't remove autotools generated files in distclean.
120 Overview of changes in lightdm 1.15.1
122 * Fix default X server command set to XMir in 1.15.0.
123 * Internally merge the [SeatDefaults] and [Seat:*] sections together. The
124 previous method meant configuration snippets using a mix of old and new
125 naming would not correctly override eachother.
126 * Use IP address of XDMCP requests to contact X server if available.
127 * Add an option for XDMCP and VNC servers to only listen on one address.

183 * Fix small memory leaks.
184 * Improve logging messages.

191 * Handle CanGraphical property on logind seats
193 Overview of changes in lightdm 1.11.7
195 * Use logind to provide the list of seats to use. Deprecate the old method
196 of manually defining seats.
