Original commit message from CVS:
add note to docs about GDP versioning; remove tmpl file
* stream. This implies that there will always be a caps packet before any
* buffer packets.
*
+ * The versioning of the protocol is independent of GStreamer's version.
+ * The major number gets incremented, and the minor reset, for incompatible
+ * changes. The minor number gets incremented for compatible changes that
+ * allow clients who do not completely understand the newer protocol version
+ * to still decode what they do understand.
+ *
* Version 0.2 serializes only a small subset of all events, with a custom
* payload for each type. Also, all GDP streams start with the initial caps
* packet.
