+title: Apache Kudu (incubating) Weekly Update July 18, 2016
+author: Todd Lipcon
+---
+Welcome to the seventeenth edition of the Kudu Weekly Update. This weekly blog post
+covers ongoing development and news in the Apache Kudu (incubating) project.
+
+<!--more-->
+
+## Development discussions and code in progress
+
+
+* Dan Burkert has continued making progress on support for non-covering range partitioned
+  tables. This past week, he posted a code review for
+  [adding and dropping range partitions to the master](https://gerrit.cloudera.org/#/c/3648/)
+  and another for [handling non-covering ranges in the C++ client](https://gerrit.cloudera.org/#/c/3581/).
+
+* Adar Dembo continued working on addressing multi-master issues, as he explained in this
+  [blog post](http://kudu.apache.org/2016/06/24/multi-master-1-0-0.html). This past week
+  he worked on [tackling various race conditions](https://gerrit.cloudera.org/#/c/3550/)
+  that were possible when master operations were submitted concurrent with a master leader election.
+
+  Adar also posted patches for most of the remaining known server-side issues, including
+  posting a comprehensive [stress test](https://gerrit.cloudera.org/#/c/3611/) which issues
+  client DDL operations concurrent with triggering master crashes and associated failovers.
+
+  As always, Adar's commit messages are instructive and fun reads for those interested in
+  following along.
+
+* As mentioned last week, David Alves has been making a lot of progress on the implementation
+  of the replay cache. Many patches landed in master this week, including:
+
+** [RPC system integration](https://gerrit.cloudera.org/#/c/3192/)
+** [Integration with replicated writes](https://gerrit.cloudera.org/#/c/3449/)
+** [Correctness/stress tests](https://gerrit.cloudera.org/#/c/3519/)
+
+  Currently, this new feature is disabled by default, as the support for evicting elements
+  from the cache is not yet complete. This last missing feature is now
+  [up for review](https://gerrit.cloudera.org/#/c/3628/).
+
+* Alexey Serbin has been working on adding Doxygen-based documentation for the public
+  C++ API. This was originally [proposed on the mailing list](https://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201606.mbox/%3CCANbMB4wtMz=JKwgKMNPvkjWX3t9NxCeGt04NmL=SyESyzUMWJg@mail.gmail.com%3E)
+ a couple of weeks ago, and last week, Alexey posted the
+ [initial draft of the implementation](https://gerrit.cloudera.org/#/c/3619/).
+
+## Project news
+
+* The [discussion](http://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201607.mbox/%3CCAGpTDNesxH43C-Yt5fNwpEpAxfb2P62Xpdi8AqT8jfvjeqnu0w%40mail.gmail.com%3E)
+  on the dev mailing list about having an intermediate release, called 0.10.0, before 1.0.0,
+  has wound down. The consensus seems to be that the development team is in favor of this
+  release. Accordingly, the version number in the master branch has been changed back to
+  0.10.0-SNAPSHOT.
