## 2.6.0
* Add `multiGet` and `multiGetCF`, which read the values of many keys in
one call to RocksDB's `MultiGet`.
* Add `blockCacheSize` to `Config`: the bytes of a least-recently-used block
cache shared by the database and all its column families. Without it
RocksDB gives each column family its own default cache, of 32 MiB in
RocksDB 8.
* Add `cacheIndexAndFilterBlocks` to `Config`, to keep the index and filter
blocks of a column family in the block cache, at high priority, with
those of level 0 pinned, instead of in memory outside the cache for every
open file.
* Stop leaking the block-based table options of every database and column
family opened with a Bloom filter.
## 2.5.0
* Add the `EstimateTableReadersMem`, `CurSizeAllMemTables` and
`BlockCacheUsage` properties, and `PropertyName` for any other property by
its name.
* Add `getPropertyCF` to read a property of a column family.
* Add `maxTotalWalSize` (`max_total_wal_size`) to `Config`, to bound the
write-ahead log.
* Add `createMissingColumnFamilies` (`create_missing_column_families`) to
`Config`, to add column families to an existing database.
* Destroy the handle of the default column family when `withDBCF` opens an
existing database. It was leaked, and RocksDB built with assertions
aborted when the database was closed.
## 2.4.0
* Add `writeBufferSize` (`write_buffer_size`) and `dbWriteBufferSize`
(`db_write_buffer_size`) to `Config`, to bound memtable memory.
## 2.3.1
* Do not call next/prev on invalid iterators (fixes assertion failure).
## 2.3.0
* Remove UnliftIO and remain in IO monad.
## 2.2.0
* Move Iterator module to plain IO.
* Properly manage read options in createSnapshot.
* Add nix flake for development.
* API allows manual database lifecycle management.
## 2.1.7
* Simplify author name.
## 2.1.6
* Refactor memory use further.
* Improve tests.
## 2.1.5
* Fix errors not releasing memory.
## 2.1.4
* Add ResourceT support for snapshots and iterators.
## 2.1.3
* Correct bug where database was ignoring prefix length config.
## 2.1.2
* Correct bug when opening database with column families.
## 2.1.1
* Expose ColumnFamily type.
## 2.1.0
* Add support for column families.
## 2.0.0
* Fork into a different project
* Rewrite most of the code to make it faster and easier to use
* Remove many features that I don't need or want to maintain
## 1.0.1
* Add support for UTF-8 characters in a database's path
## 1.0.0
* First version by Serokell
## 0.3x.0
* ResourceT is no longer compulsory
## 0.2.0
* requires LevelDB v1.7
* support for filter policy (LevelDB v1.5), either custom or using the built-in
bloom filter implementation
* write batch values no longer require a `memcpy` to be early-finalizer-safe
(introduced in 0.1.1)
## 0.1.0
* memory (foreign pointers) is managed through
[ResourceT](http://hackage.haskell.org/package/resourcet). Note that this
requires to lift monadic actions inside the `MonadResource` monad, see the
examples.
* links against shared library (LevelDB v1.3 or higher)
* LevelDB 1.3 API fully supported (including custom comparators, excluding
custom environments)
## 0.0.x
* experimental releases
