Please update runtime-net with changes in 4.4.0 of the runtime-rust

[Simon646]

The version access introduced in 4.4.0 (see Issue #88) are very useful also for grammars where there are not supposed to be multiple versions. In such cases it serves as a good diagnostic of the grammar rules. Mistakes in writing grammar rules are easy to make ... But I am a user of the runtime-net and the 4.4.0 changes have not yet made it there. If possible, please also update the runtime-net.
