+
+* [HADOOP-18830](https://issues.apache.org/jira/browse/HADOOP-18830) | *Major* 
| **S3A: Cut S3 Select**
+
+S3 Select is no longer supported through the S3A connector
+
+
+---
+
+* [HADOOP-18993](https://issues.apache.org/jira/browse/HADOOP-18993) | *Minor* 
| **S3A: Add option fs.s3a.classloader.isolation (#6301)**
+
+If the user wants to load custom implementations of AWS Credential Providers 
through user provided jars can set {{fs.s3a.extensions.isolated.classloader}} 
to {{false}}.
+
+
+---
+
+* [HADOOP-19084](https://issues.apache.org/jira/browse/HADOOP-19084) | 
*Blocker* | **prune dependency exports of hadoop-\* modules**
+
+maven/ivy imports of hadoop-common are less likely to end up with log4j 
versions on their classpath.
+
+
+---
+
+* [HADOOP-19101](https://issues.apache.org/jira/browse/HADOOP-19101) | 
*Blocker* | **Vectored Read into off-heap buffer broken in fallback 
implementation**
+
+PositionedReadable.readVectored() will read incorrect data when reading from 
hdfs, azure abfs and other stores when given a direct buffer allocator. 
+
+For cross-version compatibility, use on-heap buffer allocators only
+
+
+---
+
+* [HADOOP-19120](https://issues.apache.org/jira/browse/HADOOP-19120) | *Major* 
| **[ABFS]: ApacheHttpClient adaptation as network library**
+
+Apache httpclient 4.5.x is a new implementation of http connections; this 
supports a large configurable pool of connections along with the ability to 
limit their lifespan.
+
+The networking library can be chosen using the configuration
+option fs.azure.networking.library
+
+The supported values are
+- JDK\_HTTP\_URL\_CONNECTION : Use JDK networking library  [Default]
+- APACHE\_HTTP\_CLIENT : Use Apache HttpClient
+
+Important: when the networking library is switched back to
+the Apache http client, the apache httpcore and httpclient must be on the 
classpath.
+
+
+---
+
+* [HADOOP-18487](https://issues.apache.org/jira/browse/HADOOP-18487) | *Major* 
| **Make protobuf 2.5 an optional runtime dependency.**
+
+hadoop modules no longer export protobuf-2.5.0 as a dependency, and it is 
omitted from the hadoop distribution directory. Applications which use the 
library must declare an explicit dependency.
+
+Hadoop uses a shaded version of protobuf3 internally, and does not use the 
2.5.0 JAR except when compiling compatible classes. It is still included in the 
binary distributions when the yarn timeline server is built with hbase 1
