v3.0.3

Compare Source

Released 2024-04-07

• The default hashlib.sha1 may not be available in FIPS builds. Don't
  access it at import time so the developer has time to change the default.
  :issue:5448
• Don't initialize the cli attribute in the sansio scaffold, but rather in
  the Flask concrete class. :pr:5270
