+This is the seventh release of BookKeeper as an Apache Top Level Project!

This feature adds persistable bookies status. See [Issue-265](
for more details.
+- Introduce Bookie Discovery Interface.  Prior to this release, bookkeeper client only provides
interfaces for ledger metadata management. It doesn't provide any interface for service discovery
part. This feature introduces bookie discovery interface, so it allows plugging in different
service discovery backends for bookkeeper.
+  - Introduce Bookie Registration Manager for bookie server, see [Issue-662](
for more details.
+  - Introduce registration client for bookkeeper client, see [Issue-666](
for more details.
+- Lifecycle components for managing components in bookie server.
+  - Introduce lifecycle component for each service component, which includes "stats provider",
"auto recovery", "http endpoint", and "bookie server(both storage and netty server)", to run
these components in a clear way. See [Issue-508](
and [Issue-547]( for more details.
+- Make bookie recovery work with recovering multiple bookies. 
+  - Make recovery tool work with multiple bookies, so that one call could recover multiple
bookies. See [Issue-612]( for more details.
+### BookKeeper Admin REST API
+- Introduce a bookkeeper admin endpoint for operations to interact and administer the bookkeeper
cluster using REST API. see [PR-278](, [Issue-520](,
and [Issue-674]( for more details.
+### New BookKeeper API
+- New Fluent Style API.
+  - A brand new API to manage ledgers using the Builder pattern, and new interfaces to make
it clear operations on ledgers, like WriteHandle and ReadHandle, are provided in this release.
See [Issue-506](, [Issue-673](
and [Issue-550]( for more details
+### Performance improvement
+- Use ByteBuf in multiple places to avoid unnecessary memory allocation and reduce the garbage
produced in JVM. See [PR-640]( for more details.
+- Separate the FileInfo cache into write and read cache. It avoids catchup reads impact tailing
reads and writes. See [PR-513]( for more details.
