Sequel 4.48.0 Released

Sequel 4.48.0 was released today! Full release notes are available, but here are some highlights:

• Many additional features have been deprecated in preparation for the release of Sequel 5.
• The Model#to_json and Dataset#to_json methods in the json_serializer plugin now accept a block for customizing output.
• Dataset#as_hash has been added, allowing for the possible removal of #to_hash in cases where the definition of #to_hash causes issues.
