[Feature Request] Check for Updates in WAE.

[DaylilyLG]

Add a "Check for Updates" function in WAE.
Check for and install the latest release in WAE.

[Rampastring]

WAE has a launcher that supports automatic updates, under the MapEditorLauncher project.

There are no "official" update servers however, which is why GitHub releases do not include the updater.

The Tiberian Sun Client bundles WAE's updater and keeps WAE automatically up-to-date by hosting updates on Project Perfect Mod (PPM) servers.
