Here are the SHA1 and SHA256 checksums:

5359ea0105cedfa21a63c89b22e0d7b41b016a40  grep-3.7.tar.gz
wisM8tT2u+WZyQI4foBYmQ4e7pmu8zOiA4KeX9Pbs0I  grep-3.7.tar.gz

XBDaMSRgrschmE1dgyRtJFIOxDjdSNerWgXbwNbWgjw  grep-3.7.tar.xz

The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify grep-3.7.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver --recv-keys 7FD9FCCB000BEEEE

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.71
  Automake 1.16d
  Gnulib v0.1-4847-g1cb09be022


* Noteworthy changes in release 3.7 (2021-08-14) [stable]

** Changes in behavior

  Use of the --unix-byte-offsets (-u) option now evokes a warning.
  Since 3.1, this Windows-only option has had no effect.

** Bug fixes

  Preprocessing N patterns would take at least O(N^2) time when too many
  patterns hashed to too few buckets. This now takes seconds, not days:
  : | grep -Ff <(seq 6400000 | tr 0-9 A-J)
  [Bug#44754 introduced in grep 3.5]
