Full Changelog: v0.12.0...v0.12.2

v0.12.0

This release fully supports Chang hardfork.

Major changes

• OgmiosChainContext will now be only compatible with Ogmios v6+, underlying class being OgmiosV6ChainContext. For backward support, OgmiosV5ChainContext could be used along with Ogmios v5, but the support will be limited in the future.
• Redeemers will be serialized in a map instead of a list by default. The redeemers could be still serialized as a list by setting use_redeemer_map to False in a txbuilder.
