Room Versions
~~~~~~~~~~~~~
Room versions are used to change properties of rooms that may not be compatible
with other servers. For example, changing the rules for event authorization would
cause older servers to potentially end up in a split-brain situation due to them
not understanding the new rules.
A room version is defined as a string of characters which MUST NOT exceed 32
codepoints in length. Room versions MUST NOT be empty and SHOULD contain only
the characters ``a-z``, ``0-9``, ``.``, and ``-``.
Room versions are not intended to be parsed and should be treated as opaque
identifiers. Room versions consisting only of the characters ``0-9`` and ``.``
are reserved for future versions of the Matrix protocol.
The complete grammar for a legal room version is::
room_version = 1*room_version_char
room_version_char = DIGIT
/ %x61-7A ; a-z
/ "-" / "."
Examples of valid room versions are:
* ``1`` (would be reserved by the Matrix protocol)
* ``1.2`` (would be reserved by the Matrix protocol)
* ``1.2-beta``
* ``com.example.version``
