v0.47.1

This release introduces an in-disk implementation of most indexes, which lays the groundwork for instant startup, this includes the refactoring of the internal parts related to the indexes. The release also has some other small improvements. We skipped 0.47.0 because it had the new in-disk indexes on by default which was causing nodes to take longer to sync on our tests.

• p2p: remove peers that were disconnected and cant be reconnected anymore #365

Fixes

• indexes: make RocksDB indexes opt-in #372

Chores

• ci: dynamic matrix for reduced private fork build time #362
• code: more protobuf cleanup #347
• indexes: Move all indexes to MemoryIndexesManager #348
• indexes: Split indexes.py in multiple files #351
• indexes: remove parent-blocks-index #363
• indexes: simplify concrete managers #360
• p2p: update latest checkpoints #371

v0.46.0

This release introduces the testnet-golf, which is mostly identical to testnet-foxtrot but with a cleanup. And also drops support for Python 3.6 (which we haven't built official images for several months now).
