v10.1.0

Stability improvements

• This release contains major changes to the way stellar-core communicates with the database. The changes make the code easier to change in the future, and the immediate benefits are that the performance is improved for certain ledger types by several orders of magnitude.
• Replaying buffered ledgers during catchup may sometimes cause stellar-core to get out of sync.
• In some rare circumstances, some buckets would be deleted on startup, causing the instance to be in a corrupt state.

New features

• New command line --disable-bucket-gc that allows to disabled bucket garbage collection (used in recovery and diagnostics scenario)
• New command line option to flush the publish queue.
• Updated command line argument parsing to follow a “subcommand” syntax. Making it easier to understand the logical grouping between commands.
• Reworked all metrics (now documented in metrics.md).

Breaking changes

• The invariant CacheIsConsistentWithDatabase has been removed.

v10.0.0

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 (--newhist for 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 COMMANDS configuration element

Protocol Changes (v10)

• BumpSeqOp w/ seqnum processing changes
  • Stellar Lightning - CAP0001
• Liabilities enforced across the board
  • CAP0003
• Made offer rounding behavior more intuitive
• Moved signature verification to transaction apply step
  • CAP0002
• Fast fail not allowing to change trust on native assets

New features

• New upgradehistory table that emits meta data for upgrades
• Improved private network load testing
  • updated loadgenerator to allow for more scalable and parallel submission of synthetic traffic.
  • Documented how to do performance testing
• 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 printxdr command line option replaces printtxn to pretty print common XDR objects

Known issues

• an error is displayed when publishing to an archive, this is purely cosmetic
