v3.21.1
- Enable Closure's advanced optimization mode by default. This should reduce code size (#124).
- Replace goog.testing.asserts in tests with Jasmine expectations (#136).
- Bring in the subset of the goog.asserts we use as jspb.asserts. This code retains an Apache 2.0 license.
- Fix decoding of signed varint32s (#31).
- Add license files to NPM package.
This will also be our first release to have cross-compiled protoc-gen-js binaries. Please note that they use dynamic linking (similar to the protobuf protoc releases).
