252- The IPC mining interface now requires mining clients to use the latest
253`mining.capnp` schema. Clients built against older schemas will fail when
254calling `Init.makeMining` and receive an RPC error indicating the old mining
255interface is no longer supported. Mining clients must update to the latest
256schema and regenerate bindings to continue working. (#34568)
257- `Mining.createNewBlock` now has a `cooldown` behavior (enabled by default)
258that waits for IBD to finish and for the tip to catch up. This usually prevents
259a flood of templates during startup, but is not guaranteed. (#34184)
260- `Mining.interrupt()` can be used to interrupt `Mining.waitTipChanged` and
261`Mining.createNewBlock`. (#34184)
262- `Mining.createNewBlock` and `Mining.checkBlock` now require a `context`
263parameter.
264- `Mining.waitTipChanged` now has a default `timeout` (effectively infinite /
265`maxDouble`) if the client omits it.
266- `BlockTemplate.getCoinbaseTx()` now returns a structured `CoinbaseTx` instead
267of raw bytes.
268- Removed `BlockTemplate.getCoinbaseCommitment()` and
269`BlockTemplate.getWitnessCommitmentIndex()`.
270- Cap’n Proto default values were updated to match the corresponding C++
271defaults for mining-related option structs (e.g. `BlockCreateOptions`,
272`BlockWaitOptions`, `BlockCheckOptions`).
