I'm trying to find the source for R14B05.
The reason is that I want to see how Precise Explanation of Typing Errors was implemented. That page provides a link to the source code, but it doens't seem to be version-controlled. So I want to diff against the code is based on in order to see what changed.
The page that links to the paper says that the code is based on R14B05, so now I'd like to try diffing against R14B05.
I look at https://github.com/erlang/otp/releases?after=OTP_R16B01_RC1 or git tag -l in the repo, I can only find R14B04, then the R15 series–no R14B05.
