v0.9.3

This bugfix release continues support for Go 1.19 and 1.20, and features:

• Support inline comments in assembly to fix GOARCH=ppc64 - #672
• Avoid obfuscating reflect.Value to fix davecgh/go-spew - #676
• Fix runtime panics when using garble build inside a VCS directory - #675

Thanks to @pagran and @lu4p for their contributions!

v0.9.2

This bugfix release continues support for Go 1.19 and 1.20, and features:

• Support go:linkname directives referencing methods - #656
• Fix more "unused import" errors with -literals - #658

Thanks to @pagran and @lu4p for their contributions!

v0.9.1

This bugfix release continues support for Go 1.19 and the upcoming Go 1.20, and features:

• Support obfuscating code which uses "dot imports" - #610
• Fix linking errors for MIPS architectures - #646
• Compiler intrinsics for packages like math/bits work again - #655

Thanks to @pagran and @lu4p for their contributions!

v0.9.0

This release continues support for Go 1.19 and the upcoming Go 1.20.

Noteworthy changes include:

• Randomize the magic number header in pclntab - #622
• Further reduce binary sizes with -tiny by 4% - #633
• Reduce the size overhead of all builds by 2% - #629
• Reduce the binary size overhead of -literals by 20% - #637
• Support assembly references to the current package name - #619
• Support package paths with periods in assembly - #621

Note that the first two changes are done by patching and rebuilding Go's linker.
While this adds complexity, it enables more link time obfuscation.

Thanks to @pagran and @lu4p for their contributions!

v0.8.0
