## v2.0.0-beta.2 / 2017-08-18
## v2.0.0-beta.3 / 2017-09-12
This release includes numerous changes to the new storage layer. The main changes are:
* [CHANGES] Deterministic block boundaries
* [ENHANCEMENTS] Avoid memory usage spikes during compactions
* [CHANGES] Single, compacted write ahead log
* [CHANGES] Single in-memory block with garbage collection
* [ENHANCEMENTS] Cache series dropped via `metric_relabel_configs`
* [ENHANCEMENTS] Pool byte buffers for scraping
It's generally advised to start with a clean storage directory. As a best effort,
running `sed -i .bkp 's/generation/level/g' */meta.json` from within the directory
should be sufficient to migrate data written by v2.0.0-beta.0.
Overall the changes achieve a baseline reduction in memory consumption and reduce
peak memory usage by 30-40% compared to the 2.0.0-beta.2 release.
This release requires a clean storage directory and is not compatible with files
created by previous beta releases.
