55Noteworthy Changes:
6- - Modify the RPC handler plugin system so that it parses only the first part of
7- the URI instead of the entire path. Now plugins can implement sub-paths.
8- - Return the HTML 5 doctype for built-in UI pages
9- - Add an optional byte and/or data point limit to the amount of data fetched
10- from storage. This allows admins to prevent OOMing TSDs due to massive queries.
11- - Allow a start time via config when enabling the date tiered compaction in HBase
12- - Provide the option of using an LRU for caching UIDs to avoid OOMing writers and
13- readers with too many strings
14- - Optionally avoid writing to the forward or reverse UID maps when a specific TSD
15- operational mode is enabled to avoid wasting memory on maps that will never be
16- used.
6+ - Set default data block encoding to `DIFF` in the create table script.
7+ - Add callbacks to log errors in the FSCK tool when a call was made to
8+ fix something.
9+ - Add a sum of squares aggregator "squareSum".
10+ - Add the diff aggregator that computes the difference between the first
11+ and last values.
12+ - Add a SystemD template to the RPM package.
13+ - Allow tags to be added via HTTP header.
14+ - Add example implementations for the Authorization and Authentication
15+ plugins.

20+ - Setup fill policies in the Nagios check
