- external rpc daemon getting stuck - should be fixed
- process not exiting in a clean way (getting stuck) upon astrid errs - should be fixed
- very rare chance of bridge deadlock while at chain tip due to forking - should be fixed

Breaking changes

Bor chains: enable checkpoint sync by default (name: Astrid)
- This uses the merkle data in Checkpoints & Milestines in the sync process rather than total difficulty.
- The process should auto upgrade - in which case you may find that it starts creating new snapshots for checkpoints and milestones.
- This may however fail, as there are a number of potential edge cases. If this happens the process will likely stop with a failure message.
- In this situation you will need to do a clean sync, in which case the complete snapshot set will be downloaded and astrid will sync.
- If you want to prevent this and retain the old behaviour start erigon with --polygon.sync=false
caplin.backfilling.blobs, caplin.backfilling and caplin.archive are now --caplin.states-archive --capin.blobs-archive --caplin.blocks-archive

Description of the change

Erigon3 changes from Erigon2

Initial sync doesn't re-exec from 0: downloading 99% LatestState and History
Per-Transaction granularity of history (Erigon2 had per-block). Means:
- Can execute 1 historical transaction - without executing it's block
- If account X change V1->V2->V1 within 1 block (different transactions): debug_getModifiedAccountsByNumber return
  it
- Erigon3 doesn't store Logs (aka Receipts) - it always re-executing historical txn (but it's cheaper)
Validator mode: added. --internalcl is enabled by default. To disable use --externalcl.
Built-in Bor Consens: named Astrid. Enabled by default. To disable use --polygon.sync=false. Require re-sync.
--prune flags changed: see --prune.mode (default: full, archive: archive, EIP-4444: minimal)
Store most of data in immutable files (segments/snapshots):
- can symlink/mount latest state to fast drive and history to cheap drive
- chaindata is less than 15gb. It's ok to rm -rf chaindata. (to prevent grow: recommend --batchSize <= 1G)
Other changes:
- ExecutionStage included many E2 stages: stage_hash_state, stage_trie, log_index, history_index, trace_index
- Restart doesn't loose much partial progress: --sync.loop.block.limit=5_000 enabled by default

Require resync

Notes:

Starting with beta1 we're deprecating Caplin and Polygon support in Erigon 2
