+- Added new ATTA and DETA SVDRP commands.
+- Set the default device count to two.
+
+2015-09-18: Version 2.2.3
+
+- Added a timeout for releasing idling devices.
+- Reset the RTSP connection after any failed connect.
+- Added tweaks for minisatip and Schwaiger MS41IP.
+- Updated for vdr-2.3.1 (Thanks to Klaus Schmidinger).

+2016-12-18: Version 2.2.4
+
+- Updated German translation (Thanks to Frank Neumann).
+- Fixed Panasonic CXW804 support (Thanks to Tobias Grimm).
+- Fixed C++11 support (Thanks to Tobias Grimm).
+- Fixed server assigment with source validation (Thanks to Patrick Boettcher).
+- Added configurable RTP/RTCP ports (Thanks to chriszero).
+- Added support for X-SATIP-RTSP-Port header.
+- Added multicast and RTP-over-TCP support.

Tobias Grimm	165fd5b14a	Reorderd the transponder URL parameter in a way the Panasonic CXW804 expects them (src/freq/pol/ro/msys/mtype/plts/sr/fec) This only applies to DVB-S. DVB-C and DVB-T might need further tweaking. It's actually a bug of the Panasonic TV to expect the transponder parameters in a specific order in the query string, but for now this seems to be the most pragmatic workaround.	2016-01-08 20:25:04 +02:00
