I have been investigating issues with Homebrew formulae that don't build properly from source. One of these is mysql++. This is because the tarball does not have the expected contents (homebrew is very strict about this for security reasons -- it won't use any external resource if its hash doesn't match what was expected)

Anyway, when I try to install I see:

$ brew install -sv mysql++ [...] ==> Downloading https://tangentsoft.com/mysqlpp/releases/mysql++-3.2.5.tar.gz [...] Error: SHA256 mismatch Expected: b780beeb3a9cd9ce6a9043028527484df8e822c58c5274d4d67ec5ba2fc0a778 Actual: 839cfbf71d50a04057970b8c31f4609901f5d3936eaa86dab3ede4905c4db7a8 File: /Users/mitch/Library/Caches/Homebrew/downloads/e9e3e589ee7dc87f8942aba0e9c436a8adfb6815333ab4055dec8df1fa4078c4--mysql -3.2.5.tar.gz

The expected sha256 value was current as of 2019-07-22 when homebrew upgraded to the 3.2.5 release: https://github.com/Homebrew/homebrew-core/pull/42298/files

However looking at https://tangentsoft.com/mysqlpp/releases/ the tarball has a modification date of 2020-02-27

Can the mysql++ project verify that they intentionally republished a modified tarball and the new contents are the "official" 3.2.5 now?
