v0.54.0
This release drops support for Python 3.8, introduces a new internal settings format in YAML (the old format is still supported in this release but will be removed in the future), and changes the default values for WS_MAX_SUBS_ADDRS_CONN and WS_MAX_SUBS_ADDRS_EMPTY (which was commonly customized by several deploys, such that now they won't need to customize it anymore). Other changes include mostly the groundwork for future features.

v0.53.0
This release contains a significant number of minor improvements and fixes made in the last few months. Most notably though, is the minor sync update sync-v1.1, which basically limits the max number of peers used for the sync algorithm, instead of using all connected peers, this limits CPU usage such that sync will not affect normal node operations.
It also introduces the sysctl subsystem to modify parameters at runtime. It works with both UNIX Socket and TCP Sockets, but it is not enabled by default. You can enable it using the parameter --sysctl unix:/path/sysctl.sock or --sysctl tcp:8001. For further information and examples, check out its pull request.

Full Changelog: v0.52.3...v0.53.0
v0.52.3
This version fixes a mining API bug that was wrongly calculating the weight in specific conditions.
Fixes
- Prevent float precision error in the score when calculating the next block weight.
v0.52.1
This release adds important optimizations for runtime and startup (it should now take 5~10 min to load depending on the setup). Additionally there is some ground work for new features, and small chores related to development environments. Version v0.52.0 was skipped because of an issue that was caught after the image was built.
Features
- events: add management layer #454
- events: add storage mechanism for events #451
- indexes: make sync-v2 indexes only load when sync-v2 is enabled #486
- storage: remove binary and compact tx storage #505
- tx: improved reward lock verification algorithm #300
Fixes
- cli: builder refactor regression skipped register_resources #507
- cli: regression made it so testnet couldn't be selected #501
- init: indexes could not be used on migrations when using cache #509
- tests: fix too many files open errors #503
- tests: simple regression from #509 that ended up being merged #510

v0.51.0
This release drops support for Python 3.7, which was deprecated on v0.50.0. Additionally there are performance improvements and stability fixes, in particular the memory usage and initialization time improvements (that were previously released under the --x-rocksdb-indexes flag) are now turned on by default (they can still be turned off with --memory-indexes).
Features
- cli: make rocksdb indexes the default for rocksdb storage #494
- cli: subcommand to replay json logs as console logs #482
- cli: support to add a blacklist of peer ids in the netfilter #484
- indexes: partial optimization of tips indexes using rocksdb #480
- metrics: monitor network usage segmented by peer #467
- metrics: monitor tx cache hits/misses #466
- metrics: p2p readiness healthcheck #483
- storage: RocksDB storage monitoring #485
Fixes
- indexes: RocksDB UTXO index could miss some results #493
- metrics: peers connected metric in Prometheus #464
- p2p: Fix too many connection failures at startup #478
- pubsub: Calling events out-of-order #488
- storage: database corruption when stopping node with cache enabled #489
- sync: downloader could wrongfully re-order pending transactions #479
Chores
- python: drop support for Python 3.7 #450
v0.50.2
v0.50.1
v0.50.0
This release is fairly small, it has some small features and fixes, but also starts the deprecation of support for Python 3.7, while it is still supported this will be the last point release to do so, starting from v0.51.0 Python 3.8 will be the minimal supported version, but even then we recommend using Python 3.9 (which is the current default of the docker images) or Python 3.10.
Features
- cli: add --no-wait option to quick_test subcommand #447
- cli: add flags related to the event mechanism #434
- loading: add total to progress logger #448
- loading: optimize GC so pauses only happen when we want #445
- p2p: add client timeout to whitelist update GET request #458
- p2p: cache peer certificate options #446
Fixes
- api: validate token_uid before using it internally #449
- indexes: RocksDB empty address test fail for some multisig addresses #455
- simulator: division by zero when measuring elapsed time #462
Chores
v0.49.2
This is a small release that mainly fixes a case where it wouldn't be possible to start if the cache storage was enabled and no snapshot was used, and also a case where a wallet wouldn't load if the experimental RocksDB indexes were enabled (this was caught after v0.49.1 was built, so it was skipped and v0.49.2 is being released instead). Additionally it includes a fix to run on Ubuntu 22.04 (and possibly other recent releases of other distros).
Fixes
- cache: unexpected crash when using cache and no snapshot #436
- indexes: RocksDB empty address test implementation was broken #442
