• Delegate ActiveStorage::Filename#to_str to #to_s

  Supports checking String equality:

  filename = ActiveStorage::Filename.new("file.txt")
  filename == "file.txt" # => true
  filename in "file.txt" # => true
  "file.txt" == filename # => true

• Add support for alternative MD5 implementation through config.active_storage.checksum_implementation.

  Also automatically degrade to using the slower Digest::MD5 implementation if OpenSSL::Digest::MD5 is found to be disabled because of OpenSSL FIPS mode.

• A Blob will no longer autosave associated Attachment.

  This fixes an issue where a record with an attachment would have its dirty attributes reset, preventing your after commit callbacks on that record to behave as expected.

  Note that this change doesn't require any changes on your application and is supposed to be internal. Active Storage Attachment will continue to be autosaved (through a different relation).
