v18.1.0
Release notes:
Stability improvements
- fix: captive core crashes with all invariants enabled
- base64 commands: properly parse multi lines
- log when meta stream writes are slow. This helps diagnose when systems like Horizon are not keeping up with traffic.
- Performance updates.Switch to native uint128_t, as well as a couple pr1 and pr2.
- Remove unnecessary protocol version checks in tests
- Fuzz liquidity pools
- Add a new config to wait for merges to complete when catching up
- Windows: uint128 and bucket merge fix
- Delete TmpDirs in order before shutting down in the Fuzzer
New features
None
Breaking changes
- Remove some redundant metrics. See PR for actual list.

v18.0.3
This is a major release of stellar-core that implements “protocol 18”.
This replaces v18.0.0-18.0.2.
Protocol 18 contains the following protocol changes:
Stability improvements
- Do not fail when catching up to a protocol 18 network with invariants enabled. This only impacts fresh nodes with invariants enabled (not captive core).

Breaking changes
None
v18.0.2
This release fixes a critical issue that causes fresh nodes to fail to catchup against protocol 18 networks.
v18.0.1
This is a major release of stellar-core that implements “protocol 18”.
This replaces v18.0.0 as it fixes an issue when creating a new pool.
Protocol 18 contains the following protocol changes:
Stability improvements
- Update isBadPrice to check for 0 amounts - makes error code more user friendly when hitting a bad price
- Ensure docker builds don't use cached layers
New features
- Add code coverage configure flag
- Improve print xdr making it possible to stream basee64 encoded objects
Breaking changes
v18.0.0
Release notes:
This is a major release of stellar-core that implements “protocol 18”. Older versions will break as soon as the network gets upgraded to the latest version of the protocol.
Protocol 18 contains the following protocol changes:
Stability improvements
- Improve performance of transaction processing
- Herder: cleanup trigger ledger mechanism
- Do not call bucket manager shutdown twice. Removes bogus logging.
- Bump tracy to take change that disables building with -flto
- Minor fixes for issues detected by static analyzer
- Adjust default automatic maintenance to run faster (every 6 minutes). This reduces the load on the SQL backend (in particular the need to reclaim pages).
- Improve performance of bucket apply for captive core. Increases the chance that captive-core can restart without having to talk to history archives.
New features
- Add --enable-tracy-csvexport. Allows capturing Tracy counters in csv form.
- Add a new command to gather information on any given bucket.
Breaking changes
- Bump overlay version to 18. Disconnect clients older than 17.0.0

v17.4.0
Release notes:
Stability improvements
- Work shouldn't be scheduled once WorkScheduler is done - fixes a potential crash on shutdown
- Add CONFIGURE_FLAGS argument to Dockerfile.testing to give better control when building ad-hoc containers
- Bring db-schema.md up to date
- Record and check TxMeta produced by tests. Strengthen testing.
- Create multi-operation transactions in LoadGen . Allows to better simulate network patterns in large scale simulations.
- Remove a confusing error message in
sendMessage - replace use of "assert" by releaseAssert*. Hardening regardless of build flags.
- Improve invariance in Herder. Simplifies herder state machine in preparation for more changes.
- ApplyLedgerWork fails correctly
- Remove unnecessary protocol checks. Consolidates protocol 14 and 15 to avoid confusion.
- Add test for op source acc to claim sponsored non native balance
- Resize ccache in ci-build.sh. CI improvement
- reduce memory usage of asan in ci. CI improvement.

v17.3.0
Stability improvements
- Retry DNS resolution faster on startup. Speeds up connection establishment in certain scenarios (particularly Kubernetes automatic DNS provision).
- In memory mode wants SOCI transactions. Fixes a rare atomicity bug that can prevent successful crash-recovery of a captive core.
- Herder tracking cleanup and tests
- Additional startup checks
- SCP / Quorum utils: Minor fixes to reduce dependencies
- Add unit tests for application setup
- Minor logging changes:
New features
- Add
encode-assetcommand for debugging - Groundwork for CAP-0038, not yet used:
Breaking changes
- Store LedgerEntry in trustline table. Marked as a breaking change for visibility: no code or configuration needs to change, but on upgrade stellar-core will perform an automatic SQL schema migration, and will be unavailable to sync with its peers until this migration completes. On a fast SSD running on SQLite, the migration may be as quick as 2 minutes; on a slow spinning disk running on postgres it may take a half hour or more. Nodes should therefore be upgraded gradually and individually to avoid disruption.
