Protocol numbers

Hedgewars uses protocol numbers to encode different Hedgewars versions. The protocol number is mainly used on the server. The protocol number is important because players have to be on the same version to play together.

In Hedgewars, all versions without a “-dev” are called “stable” releases. These are the releases you find on the official Download page. Note that for some releases, the protocol number is not increased. This is the case for backwards-compatible bugfix releases. Thus, protocol number 55 is valid for 0.9.24 and 0.9.24.1.

A “-dev” in the version number means it is a version in development. This is not really a specific version, more like a shorthand. A version X.Y.Z-dev means that it could be a build of any commit after the previous stable relese but before the next stable release X.Y.Z.

E.g. the development version before 0.9.24 is 0.9.24-dev.

Since 0.9.25-dev, you can run “ hwengine --protocol ” in the commandline to get the current protocol number of your installed Hedgewars.
