{: #v1-7-0}
-One notable change is that the use of JUL (java.util.logging) has been replaced
-with [SLF4J](http://slf4j.org/). SLF4J provides an API which Calcite can use
-independent of the logging implementation. This ultimately provides additional
-flexibility to users, allowing them to configure Calcite's logging within their
-own chosen logging framework. This work was done in [CALCITE-669](https://issues.apache.org/jira/browse/CALCITE-669).
+This is the first release of Avatica as an independent project. (It
+is still governed by Apache Calcite's PMC, and stored in the same git
+repository as Calcite, but releases are no longer synchronized, and
+Avatica does not depend on any Calcite modules.)
-For users experienced with configuring JUL in Calcite previously, there are some
-differences as some the JUL logging levels do not exist in SLF4J: `FINE`,
-`FINER`, and `FINEST`, specifically. To deal with this, `FINE` was mapped
-to SLF4J's `DEBUG` level, while `FINER` and `FINEST` were mapped to SLF4J's `TRACE`.
+One notable technical change is that we have replaced JUL (`java.util.logging`)
+with [SLF4J](http://slf4j.org/). SLF4J provides an API that Avatica can use

+
+If you have configured JUL in Calcite/Avatica previously, you'll
+notice some differences, because JUL's `FINE`, `FINER` and `FINEST`
+logging levels do not exist in SLF4J. To deal with this, we mapped
+`FINE` to SLF4J's `DEBUG` level, and mapped `FINER` and `FINEST` to
+SLF4J's `TRACE`.
+
+The performance of Avatica was an important focus for this release as well.
+Numerous improvements aimed at reducing the overall latency of Avatica RPCs
+was reduced. Some general testing showed an overall reduction of latency
+by approximately 15% over the previous release.
+
+Compatibility: This release is tested on Linux, Mac OS X, Microsoft
+Windows; using Oracle JDK 1.7, 1.8; Guava versions 12.0.1 to 19.0;
+other software versions as specified in `pom.xml`.

+This marks the separation of Avatica from its previous location as a sub-module
+of Apache Calcite's Maven build.
+
+This separation is not to remove Avatica from
the governance of the Apache Calcite project, but to allow for even more rapid
releases from both the Avatica and Calcite projects. We can confidently make new
releases of each without having to worry about the current state of development
