Spring v1.0.0-rc2
Pre-release
Antelope Spring is the successor to Leap as the C++ implementation of node software for blockchain networks based on the Antelope Protocol.
Spring v1.0.0 introduces Savanna consensus, which reduces time to finality from 3 minutes to 1 second under typical network conditions.
Also featured in Spring 1.0.0 is a significant reworking of the State History Plugin to improve performance, reliability, and support cross block chain consensus leveraging the faster finality of Savanna.
Note
To maintain IBC compatibility with EOS after it transitions to Savanna consensus, other Antelope chains will need to upgrade to a Savanna compatible IBC contract which depends on the activation of the BLS protocol feature that was first introduced in Leap v5.0.0.

Fixed in Spring v1.0.0-rc2
Snapshots
- v7 snapshot loading failures
- Loading from snapshot with block strides
- Check for
chain_head.daton snapshot load - treat a end_block_num=0 as "forever" in snapshot scheduler for compatibility with leap 4.0
Syncing
- P2P: Sync not making progress after a timeout and reassign_fetch
- P2P: Sync mode stuck after hitting max-reversible-blocks, after restart
- P2P: Limit requested blocks to avoid max-reversible-blocks
- max-reversible-blocks syncing old blocks
Other
- log entry for legacy producer schedule broken in rc1
- Add changes required for updating to boost 1.86 - but without the boost upgrade
- Update chainbase to tip (initialization / move operations update)
- fix true_lowest() for uint128[2] index; possibly resolving some secondary table row RPC queries
- limit the vector size that can be reserved
- Remove unnecessary code that cannot be executed.
- Create Savanna unittests modeled after the fast testnet wave tests
