I need the version to be at least something like `1.0.0-nightly-2026-05-23` My lemmyApi uses this version to determine how to swap between clients. If i can't read the version, I don't know which client I can use to interpret the JSON. https://voyager.lemmy.ml/nodeinfo/2.1 ```json {"version":"2.1","software":{"name":"lemmy","version":"nightly-2026-05-23","repository":"https://github.com/LemmyNet/lemmy","homepage":"https://join-lemmy.org/"},"protocols":["activitypub"],"usage":{"users":{"total":49,"activeHalfyear":31,"activeMonth":31},"localPosts":41,"localComments":56},"openRegistrations":true,"services":{"inbound":[],"outbound":[]},"metadata":{}} ``` ### Steps to Reproduce 1. go to https://voyager.lemmy.ml/nodeinfo/2.1 ### Technical Details n/a ### Version 1.0.0 ### Lemmy Instance URL voyager.lemmy.ml
