This is a small release that took a huge amount of work.
For those who don’t know the v1 release of Lemmy has been in beta for a while now. The v1 release of Lemmy ships with Lemmy API v4 with backwards compatibility with Lemmy API v3.
Lemmy API is the shared language of how clients (Summit) and server talk to one another. Lemmy releases are loosely tied to API versions. So for instance, Lemmy v0.19 (which is the version most servers use) only supports Lemmy API v3. Currently Summit only supports v3 of the Lemmy API. This release adds support for API v4.
This is mostly a future proofing measure since Lemmy v1 will still support API v3. Since Lemmy v1 isn’t released yet it’s likely there are still bugs in the API v4 support implementation as there were many massive changes. Due to this API v4 is disabled by default. Once Lemmy v1 releases and I can verify the app is stable with API v4 it will be turned on by default.
So basically this update doesn’t actually add anything, yet.
