v0.20.0

0.20.0 - 2026-07-10

New Features

• Support both sbt 1 and sbt 2

  sbt-github-pages is now cross-published for both sbt series from a single source tree.

  sbt series	Scala	Artifact
  sbt 1 (1.11.2+)	2.12.20	io.kevinlee:sbt-github-pages_2.12_1.0
  sbt 2 (2.0.1)	3.8.4	io.kevinlee:sbt-github-pages_sbt2_3

  addSbtPlugin("io.kevinlee" % "sbt-github-pages" % "0.20.0") resolves the right one for you,
  so no change is needed in project/plugins.sbt.

  The minimum supported sbt 1 version is unchanged (1.11.2).

  Note that building the sbt 2 artifact requires JDK 17 or later, because that is what the
  Scala 3.8.4 compiler requires. Using the plugin does not.

Internal

• All tasks (publishToGitHubPages, gitHubPagesBranchExists, gitHubPagesGetCurrentBranch and
  gitHubPagesCreateGitHubPagesBranchIfNotExist) are now marked Def.uncached. sbt 2 caches every
  task by default, which would have made the git-shelling tasks return stale answers within a
  single session, and would have made publishToGitHubPages a no-op on its second invocation.

• Replaced http4s-blaze-client with http4s-ember-client. Blaze is no longer maintained in step
  with the rest of http4s (it is pinned at 0.23.17 while http4s itself is at 0.23.36).

• Added unit tests (hedgehog) and scripted tests for both sbt 1 and sbt 2.
