Hi Gophers!

...and happy New Year! This release brings GopherJS's upstream Go support up to 1.20.14 version. Moreover, we've had time to exercise the new generics support for a bit and it seems to be doing alright - kudos to @grantnelson-wf for his continued efforts! Since our language support is again on par the the spec, we are back to tagging stable releases! 🥳

In addition to the newer Go version, this release brings improved sourcemaps, which now cover .inc.js and prelude sources (#1393) and preserve original Go function names (#1392). Enjoy cleaner panic traces! 😁
