Minor features / improvements

• Added a new spx:transport attribute to SVG media elements to specify the RTP transport to use when controlling the session via RTSP, valid values are the following
• Tcp: request RTP streaming interleaved within the RTSP TCP connection, this allows to do RTP / RTSP streaming over NAT routers and firewalls which do not have transparent RTP / RTSP support but has the disadvantages of TCP based streaming (i.e. head of line blocking and conflicting TCP rate control) causing uncontrolled delay under adverse network conditions
• Unicast: request unicast RTP streaming over UDP
• Multicast: request multicast RTP streaming (always UDP)
• Attribute not set: use the server's default, typically unicast or multicast RTP over UDP
• The JavaScript variable document.documentElement.previewMode can now take the following values
• 0: normal mode
• 1: preview mode (can be used to generate custom preview in IS-Xpress)
• Added Spanish translation

Bug Fixes

• Documents with a fixed begin time well in the past but with content of known length could take a long time to open
• Resuming a paused video element would crash if the element's end was used as the begin or end time of another SMIL element
• Some visual glitches could occur in the rendering of the first frame of an animation
• JavaScript DOM API:
• Leading and trailing whitespace in the textContent property of an element was not preserved as required by the DOM API
• parseRSS() would return incorrect enclosures when the link is the same for all items
• Rendered objects could be incorrectly clipped when their position was animated
• A rare race condition in the log framework could cause a crash
• IS-Xpress created an invalid index.svg file when running under the German language
• The playlist template was updated to avoid the possibility that the playlist is detected as finished before its actual end, affected playlists need to be recreated after upgrading IS-Xpress
• IS-Xpress rendering of Arabic text in the preview was incorrect (regression in IS-Xpress 2.2.3)
• Line breaking of Arabic and Indic languages was not correct in IS-Xpress
• IS-Xpress could occasionally crash when saving a preview due to a race condition
• If the user attempted to open a non-SVG file from an HTTP location for preview, IS-Xpress could keep retrying every 10 seconds instead of returning an appropriate error message to the user
• IS-Xpress would not properly recognize a URL without path (e.g., http://spx-001d500001f1.local) as being the root path by implicitly adding the missing slash at the end
