Among other things, the minor releases from 18.1.1 to 18.1.10 include
- performance improvements to the query planning and execution engine
- performance improvements for summarize operator
- a bug-fix for arrays with compression turned on
- security namespaces are now first-class names in AFL, so you no longer need to provide them as string literals to the various namespace operators
For the above reasons, upgrading to the latest 18.1 version is highly recommended.
As noted at this post, if you are upgrading from <18.1.7 to greater, you would need to recompile plugins too. A little bit of a pain, but it will be worth it
We will keep you posted about other minor releases on this thread.
