 # No need to go get, as github knows its working out of this folder.
 #
-# Most of our code is the same since go1.12; before that we selectively compile files using build constraints.
-#
 # We test against the following go releases
 # - latest production release
 # - 2 releases before that
-# - an archive version (go 1.11)
 # - and a beta/rc of development release (so github can just download an archive of it and use)
 #
 # Pre-release versions must use semver e.g. as of 20221220, it's '1.20.0-rc.1' 
-# TODO: add this back once we resolve the issue with go-codec failing on development branch.
 #
 # We test amd64 on all releases, and i386 (32-bit) on last production release.
 #
-# We previously had each tag be its own matrix, but that exploded the number of runs.
-# Instead, since the environment is consistent, we just use a bash script to run through all
-# the tags for that run.
-#
 # Finally, we do a go mod edit -droprequire github.com/ugorji/go to circumvent the "missing go.sum entry" error.
 # We put a requirements cycle with github.com/ugorji/go to allow folks requiring .../ugorji/go in 2019 to work ok.
 # Now, everyone should have updated to a go-codec version >= 1.17 or preferably >= 1.2.0.
