This release includes changes to the protocol as well as some stability improvements.
As it changes the meta data format, a newer version (0.14.0 or greater) of Horizon is required.
Stability improvements
- Avoid 100% CPU usage when running certain commands (
--newhistfor example). - Handshake code in overlay had issue that would lead to peers not able to an error “unexpected MAC”.
- Align publish with network consensus, this avoids potentially publishing bad ledgers in case of corruption.
- Align catchup with network consensus, this avoids having to rely on timing (which may cause significant delays in catchup).
- Properly fail work when spawning a process throws an exception.
- Transactions are better flooded on the network.
- SCP: synchronize nodes over time to reduce chance of timeout
- SCP: nomination was sometimes computing “round leader” improperly, leading to timeouts
- SCP: ensure latest quorum information is used when whitelisting validators
- SCP: fix an edge case (present in current revision of the whitepaper), where a validator would improperly set its internal set leading to a crash
- Move to a more recent version of asio.
- Reduced number of warnings.
- Properly kill subprocesses.
- Moved to
Catch2(testing). - Moved to c++ 14 for the toolchain.
- Fixed a crash when using the
COMMANDSconfiguration element

- updated
- New metrics:
- archive health
- performance characteristics of validators and network
- Validators can now be configured to upgrade to protocol versions other than the latest supported.
- Support for running tests in parallel
- new
printxdrcommand line option replacesprinttxnto pretty print common XDR objects
Known issues
- an error is displayed when publishing to an archive, this is purely cosmetic
