Notes:

Client side demos recorded onwards will be better aligned to the gameplay protocol to support extended attributes. Enough of PEXT_TRANS was implemented back in 2013 for alpha attribute to be read correctly (but will be rendered opaque if outdated), but if colormod is used, outdated clients will not be able to play the MVD/QTV stream. Outdated clients will also not be able to correctly ingest a MVD/QTV stream with the amount of models and entities the fully connected gameplay protocol supports. Those limits used to be simply cut off, corrupting the demo over time, but in practice these limits were rarely if ever surpassed with old content.

As ezQuake has incorrectly announced support for PEXT_TRANS since 2013, the server must identify faulty clients by revision. The cutoff of working alpha support if the client is named ezQuake is 7814. Official builds always have a correct revision set, scuffed ones may have revision as 1, so make sure you're not using a shallow clone when building on your own, or build from the official release source tarball.

In practice this shouldn't be much of an issue given how many vulnerabilities lurk in older releases.
