### Public API Change
* Introduced `CompressionOptions::kDefaultCompressionLevel`, which is a generic way to tell RocksDB to use the compression library's default level. It is now the default value for `CompressionOptions::level`. Previously the level defaulted to -1, which gave poor compression ratios in ZSTD.
+### Bug Fixes
+* Fix segfault caused by object premature destruction (PR #3898)
+* Fix an issue with unnecessary capture in lambda expressions (PR #3904)

## 5.13.1 (4/30/2018)
### New Features
* Add `Env::LowerThreadPoolCPUPriority(Priority)` method, which lowers the CPU priority of background (esp. compaction) threads to minimize interference with foreground tasks.
