+# Apache Hadoop 3.2.1 Release Notes
+
+These release notes cover new developer and user-facing incompatibilities, important issues, features, and major improvements.
+
+
+---
+
+* [YARN-8986](https://issues.apache.org/jira/browse/YARN-8986) | *Minor* | **publish all exposed ports to random ports when using bridge network**
+
+support -p and -P for bridge type network;
+
+
+---
+
+* [YARN-9071](https://issues.apache.org/jira/browse/YARN-9071) | *Critical* | **NM and service AM don't have updated status for reinitialized containers**
+
+In progress upgrade status may show READY state sooner than actual upgrade operations. External caller to upgrade API is recommended to wait minimum 30 seconds before querying yarn app -status.
+
+
+---
+
+* [YARN-9084](https://issues.apache.org/jira/browse/YARN-9084) | *Major* | **Service Upgrade: With default readiness check, the status of upgrade is reported to be successful prematurely**
+
+Improve transient container status accuracy for upgrade.
+
+
+---
+
+* [HADOOP-15922](https://issues.apache.org/jira/browse/HADOOP-15922) | *Major* | **DelegationTokenAuthenticationFilter get wrong doAsUser since it does not decode URL**
+
+- Fix DelegationTokenAuthentication filter for incorrectly double encode doAs user parameter.
+
+
+---
+
+* [YARN-8761](https://issues.apache.org/jira/browse/YARN-8761) | *Major* | **Service AM support for decommissioning component instances**
+
+- Component instance number is not linear increment when decommission feature is used. Application with assumption of linear increment component instance number maybe impacted by introduction of this feature.
+
+
+---
+
+* [HDFS-14305](https://issues.apache.org/jira/browse/HDFS-14305) | *Major* | **Serial number in BlockTokenSecretManager could overlap between different namenodes**
+
+NameNodes rely on independent block token key ranges to communicate block token identities to DataNodes and clients in a way that does not create conflicts between the tokens issued by multiple NameNodes. HDFS-6440 introduced the potential for overlaps in key ranges; this fixes the issue by creating 64 possible key ranges that NameNodes assign themselves to, allowing for up to 64 NameNodes to run safely. This limitation only applies within a single Namespace; there may be more than 64 Na [...]
+
+
+---
+
+* [HDFS-14396](https://issues.apache.org/jira/browse/HDFS-14396) | *Blocker* | **Failed to load image from FSImageFile when downgrade from 3.x to 2.x**
+
+During a rolling upgrade from Hadoop 2.x to 3.x, NameNode cannot persist erasure coding information, and therefore a user cannot start using erasure coding feature until finalize is done.
+
+
+---
+
+* [YARN-7055](https://issues.apache.org/jira/browse/YARN-7055) | *Major* | **YARN Timeline Service v.2: beta 1 / GA**
+
+Application Timeline Server v2 is ready for production. It is GA from 3.2.1 release on wards.
