Release Notes - v0.207.0

v0.207.0

Title: Improve shutdown signaling, panic handling, and pool metadata compatibility

Version: v0.207.0

This release makes protocol shutdown observable sooner, improves diagnostics when protocol and pipeline workers panic, and accepts pool metadata hashes with lengths other than 32 bytes.

New Features

• Improved panic handling for protocol-owned goroutines and pipeline workers by recovering panics and reporting diagnostics. Ordered pipeline processing continues, while a fatal worker failure cancels the pipeline when necessary.
• Added (*protocol.Protocol).StopChan() for immediate shutdown request observation when Stop() runs. StopChan() closes separately from DoneChan(), which signals completed shutdown.

Breaking Changes

• Expanded local state query pool metadata decoding to use ledger/common.PoolMetadataHash. The decoder now accepts metadata hashes with lengths other than 32 bytes, and the exported field uses this type instead of fixed-width ledger.Blake2b256.
