Scala Native v0.3.8 Release Notes

Release Date: 2018-07-16 // almost 6 years ago

  • πŸš€ This release focuses on compatibility and performance improvements in the library code, keeping backward binary compatibility with previous releases in 0.3.x series.

    🍱 Highlights ✨

    🍱 Default garbage collector πŸ—‘οΈβ™»οΈ

    (by @ekrich)

    πŸš€ Starting from 0.3.8, Immix is the default garbage collector. Over the past year of testing, we confirmed that it offers major performance improvements over the Boehm GC. To revert back to the previous collector you can set the following setting in your build file:

    nativeGC := "boehm"

    πŸ‘Œ Improved performance of File I/O πŸ’Ύ

    (by @eatkins and @henrymai)

    🐎 0.3.8 provides a series of library improvements that aim to increase the performance of the NIO library layer for File I/O operation. Changes include major speedups across reading, writing and walking file trees.

    πŸ— Test runner for 3-rd party build tools πŸ—οΈ

    (by @Duhemm)

    πŸ— In 0.3.7 we introduced a Build tool API interface that simplifies integration of Scala Native toolchain into 3-rd party build tools. In 0.3.8 we expand this to also include preliminary support for running tests through newly factored out unit test runner.
