v1.8.0

Hi wazero friends, been a while! The new release of wazero v1.8.0 has arrived 🎉 🏝️☀️ 🍺

This release has happened intentionally right after the Go 1.23 release. @​ncruces worked so hard (#2301), and updated our codebase to make it up-to-date with the new Go versions. Notably, since this release, we set our floor Go version to 1.21 (-2 from the latest) following our support policy.

The following is the brief summary of what's included in this release!

Experimental feature: importResolver

A new wazero friend @​bep from the Hugo community came up with an exciting way to "link" modules dynamically/anonymously, which we call "ImportResolver". The feature was implemented in #2298, and available under experimental package. If you are interested please give it a shot, and give us your feedback!

Emscripten update

@​jerbob92 found out that a breaking change was introduced in Emscripten 3.1.57+, and worked to make our emscripten package to support these recent versions. Unfortunately, the older emscriptens are not supported anymore, so users are encouraged to update their Emscripten version. #2290

Bug fixes

• threads: lock around invocations of memory.Grow (#2279) @​anuraaga
• amd64: fixes lowerSqmulRoundSat (#2260) @​mathetake

Compilation perf improvements

Just like the recent previous releases, @​mathetake worked hard to make compilation faster. Unfortunately, we don't have a concrete number to showcase here, but both Interpreter and Compiler engines now runs really faster compared to the previous releases during compilation without affecting the runtime performance.

If you are interested in the latest updates and discussion around this topic, feel free to follow the thread in #2182.

v1.7.3

Time to celebrate the new wazero release! This time has not only the important bugs fixes just like before, but more importantly comes with the drastic "compilation time" performance improvements!

Bug fixes

• Various WASI related bug fixes contributed by @​yagehu #2244 #2229 #2223
• Syscall compatibility fix on Windows by @​ncruces #2218
• api.Memory.Grow call bug introduced in v1.7.0 by @​mathetake #2216 (thanks to @​mark-pictor-csec for reporting)

Compilation perf improvements

@​mathetake worked so hard to improve the compilation performance which some users had raised issue about since the release of the optimizing compiler in 1.7.0. The idea is that even though this is partly because it is "optimizing", there are still rooms for improvements in its codebase to use less CPU/memory.
