+* [HBASE-22149](https://issues.apache.org/jira/browse/HBASE-22149) | *Critical* | **HBOSS: A FileSystem implementation to provide HBase's required semantics on object stores**
+
+<!-- markdown -->
+
+Initial implementation of the hbase-oss module. Defines a wrapper implementation of Apache Hadoop's FileSystem interface that bridges the gap between Apache HBase, which assumes that many operations are atomic, and object-store implementations of FileSystem (such as s3a) which inherently cannot provide atomic semantics to those operations natively.
+
+The implementation can be used e.g. with the s3a filesystem by using a root fs like `s3a://bucket/` and defining
+
+* `fs.s3a.impl`  set to `org.apache.hadoop.hbase.oss.HBaseObjectStoreSemantics`
+* `fs.hboss.fs.s3a.impl` set to `org.apache.hadoop.fs.s3a.S3AFileSystem`
+
+more details in the module's README.md
+
+NOTE: This module is labeled with an ALPHA version. It is not considered production ready and makes no promises about compatibility between versions.

+
+* [HBASE-22393](https://issues.apache.org/jira/browse/HBASE-22393) | *Critical* | **HBOSS: Shaded external dependencies to avoid conflicts with Hadoop and HBase**
+
+<!-- markdown -->
+
+HBOSS now generates a single jar file that can be dropped into an HBase installation. This jar contains the thirdparty dependencies needed for HBOSS's implementation and communication with ZK (for the ZK Lock Manager).
+
+HBOSS still relies on both HBase and Hadoop jars to be present at runtime. It also relies on the slf4j-api jar. It no longer includes an slf4j binding by default.
