title: Apache BookKeeper 4.8.1 Release Notes
---
-This is the 13th release of Apache BookKeeper!
+This is the 14th release of Apache BookKeeper!
-The 4.8.1 release incorporates hundreds of bug fixes, improvements, and
features since previous major release, 4.7.0.
-It is a new big milestone in Apache BookKeeper community,
-this release include great new features, like Relaxed Durability, Stream
Storage service and Multiple active Entrylogs.
+The 4.8.1 release is a bugfix release which fixes a bunch of issues reported
from users of 4.8.0.
-Apache BookKeeper/DistributedLog users are encouraged to [upgrade to
4.8.1](../../admin/upgrade). The technical details of
-this release are summarized below.
+Apache BookKeeper users who are using 4.8.0 are encouraged to upgrade to
4.8.1. The technical details of this release are summarized
+below.
## Highlights
-The main features in 4.8.1 are around following areas:
+- Use default metrics registry in Prometheus exporter, see
[apache/bookkeeper#1765](https://github.com/apache/bookkeeper/pull/1765)
-- Durability
-- ExplicitLAC feature
-- New Table Storage Service
-- Bug Fixes
+- Don't cache Bookie hostname DNS resolution forever, see
[apache/bookkeeper#1762](https://github.com/apache/bookkeeper/pull/1762)
+- Reduce stack traces in logs for common cases, see
[apache/bookkeeper#1762](https://github.com/apache/bookkeeper/pull/1776)
-### New WriteFlag DEFERRED_SYNC
+- Ledger deletion racing with flush can cause a ledger index to be
resurrected, see
[apache/bookkeeper#1757](https://github.com/apache/bookkeeper/pull/1757)
-The writer may ask for temporary relaxed durability writes, that is to receive
early acknowledge from Bookies, before an fsync() on Journal.
-Together with this new flag we introduced the new WriteHandle#force() API,
this this API the writer is able to request an explicit guarantee of durability
to the Bookies
-it is mostly like and explicit fsync() on a file system.
+- EntryMemTable.newEntry retains reference to passed ByteBuffer array, can
cause corruption on journal replay, see
[apache/bookkeeper#1737](https://github.com/apache/bookkeeper/pull/1737)
-See [`DEFERRED_SYNC`](../javadoc/org/apache/bookkeeper/client/api/WriteFlag)
and [force()](../javadoc/org/apache/bookkeeper/client/api/ForceableHandle) for
reference
-### New behaviour for Netty ByteBuf reference count management
+### Dependency Changes
-All the client side APIs which take ByteBufs now will have the net effect of
decrementing by 1 the refcount.
-This is consistent with general contract of Netty.
-It is expected that the client passes the ownership of the ByteBuf to
BookKeeper client.
-
-### Multiple Active Entrylogs
-
-It is now possible on the Bookie to have multiple active entry loggers,
-this new feature will help with compaction performance and some specific
workloads.
-
-See [Multiple active
entrylogs](https://github.com/apache/bookkeeper/issues/570)
-
-### Table Storage Service
-
-From this version we are providing the a table (key/value) service embedded in
Bookies.
-
-See [BP-30: BookKeeper Table
Service](https://github.com/apache/bookkeeper/issues/1205)
-
-### Make ExplicitLAC persistent
-
-ExplicitLAC was contributed from Salesforce in 4.5.0 release, but in the first
release
-it was a beft-effort in-memory mechanism. Now you can configure Bookies to
store durably ExplicitLAC.
-
-See [Make ExplicitLAC
persistent](https://github.com/apache/bookkeeper/issues/1527)
-
-### Ensemble change on Delayed Write Failure
-
-We are handling more gracefully the case of a failure of a Bookie in spite of
a succeeded write.
-If you are writing with Ack Quorum = 2 and Write Quorum = 3, writes will
succeeed even if 1 of 3 Bookies fail,
-now BookKeeper will trigger an *ensemble change* and replace the failed bookie
earlier.
-
-See [Ensemble change on Delayed Write
Failure](https://github.com/apache/bookkeeper/issues/1390)
+There is no dependecy upgrade from 4.8.0.
