| This is a fast-track release to replace a broken release 3.6.0 that occurred during the Scala 3.6.0-RC1 release. It might contain bugs that would be fixed during the Release Candidate bugfixes period. We recommend waiting for the stable Scala 3.6.2 release. | ||
|
|
||
| Scala 3.6.0 should be never used to produce libraries. TASTy files produced by this version of compiler are produced in the experimental mode. These outputs are not compatible with consumers using stable versions of the compiler. | ||
|
|
