v0.20.4

0.20.4 (2026-05-21)

Stryker4s now works properly on multi-module projects! Simply running sbt <module-name>/stryker will run Stryker4s on the specified module. The workaround of sbt 'project <module-name>; stryker' is no longer necessary. Thanks to @rwaldvogel for the contribution!

• sbt: scope task queries to the invoking project (#1994) (bfbe167)
• sbt: strip -Werror alongside -Xfatal-warnings (#1999) (afb2e50)

v0.20.0

0.20.0 (2026-03-16)

This release uses the new support in FS2 for Unix sockets to communicate with test-runners. Stryker4s will seamlessly use either native Unix file sockets, or the "old" TCP sockets, whichever is available. This should give slightly improved performance and stability. If you run into any issues, please let us know!

• connect to testrunner over unix sockets, if available (#1834) (3921e7c)
• report: output HTML report as single file (#1867) (cd60269)
• scala-dialect: support Scala 3.8 (#1883) (810c600)

• compatibility with java 8 (#1837) (be4590f)
• cross-compile to Scala 3 LTS, instead of for SBT2 (#1840) (6e853ed)
