## 0.8.0
* Updated for Streamly 0.10.0.
* Added proper concurrency support, including safety upon asynchronous exceptions. (The previous versions were unreliable in concurrent settings—segfaults, deadlocks, etc.)
* A byproduct of the previous point: `writeLMDB` no longer maintains its own read-write transactions under the hood.
* Added the ability to chunk the read-only transactions (by bytes or number of pairs) that `readLMDB` can create under the hood.
* Added the ability to use read-write transactions for `readLMDB`.
* Eliminated the `Void` seed for `readLMDB`.
* Added more choices for `readStart`.
* Added the ability to stream unexpected key-value pairs in `writeLMDB` into a separate fold.
* Added `getLMDB` for getting a single key-value pair normally (without streaming).
* Added `writeLMDBChunk` for writing key-value pairs normally (without streaming).
* Added `chunkPairs`/`chunkPairsFold` convenience functions that allow chunking a stream of key-value pairs (by bytes or number of pairs).
* Added `deleteLMDB` for deleting key-value pairs.
* Made the unsafe FFI functionality internal.
* Improved documentation, esp. regarding caveats for long-lived transactions and various lower-level LMDB requirements.
## 0.7.0
* Added `readUnsafeFFI` and `writeUnsafeFFI` options.
## 0.6.0
* Updated for Streamly 0.9.0.

## 0.3.0

## 0.2.0
* Added read options for backward reading and starting from a specific key.
## 0.1.0

## 0.0.1.1
* Fixed `install-includes` and `include-dirs` in the Cabal file.
* Added safety check for bound threads in `writeLMDB`.
