0.5.0 (2026-03-30)

Minor Changes

• Added access key signing support for Tempo transactions. When root_account is set, nonce and gas estimation now use the root account (smart wallet) address, transactions are signed via sign_tx_access_key, and the credential source reflects the root account rather than the access key address. (by @brendanryan, #103)
• Added RedisStore and SQLiteStore backends to mpp.stores for replay protection, with optional extras (pympp[redis], pympp[sqlite]). Added store parameter to Mpp.__init__ and Mpp.create() that automatically wires the store into intents supporting replay protection. (by @brendanryan, #103)

Patch Changes

• Raised test coverage by adding tests for edge cases across charge, parsing, server, and store modules, and updated CI to generate and upload XML/HTML coverage reports for Python 3.12. (by @brendanryan, #103)
• Fixed fail-closed expiry enforcement in ChargeIntent.verify: requests with a missing expires challenge parameter are now rejected instead of silently allowed through. (by @brendanryan, #103)
