order timestamps for bulk ingest.
- NOTE: This version also includes a JDK 8 compiled version of Jackson due to
security patches. If you need to run with an older JDK please replace the

than the query start timestamp. This helps with calendar downsampling intervals.
- Add support to the Nagios check script for downsampling fill policies.

output types for boolean values.
- Fixing missing tools scripts in builds.
- Default HBase 1.2.5 in the OSX install script

finalannotation from the meta classes so they can be extended.

- Fix the Highest Current calculation to handle empty time series.
- Change the cache hits counters to longs.
- Version 2.4.0 RC2 (2017-10-08)
- Modify the RPC handler plugin system so that it parses only the first part of
the URI instead of the entire path. Now plugins can implement sub-paths.
- Return the HTML 5 doctype for built-in UI pages
- Add an optional byte and/or data point limit to the amount of data fetched
from storage. This allows admins to prevent OOMing TSDs due to massive queries.

- Provide the option of using an LRU for caching UIDs to avoid OOMing writers and
readers with too many strings
- Optionally avoid writing to the forward or reverse UID maps when a specific TSD
operational mode is enabled to avoid wasting memory on maps that will never be
- Roll back UTF8 issue with UIDs in RC1 wherein the stored bytes weren't converting
properly and vice-versa. We'll have to work on full UTF8 support in 3.x

- Version 2.2.2 (2016-12-29)
- Fix an issue with writing metadata where using custom tags could cause the compare-
and-set to fail due to variable ordering in Java's heap. Now tags are sorted so the
custom tag ordering will be consistent.
- Fix millisecond queries that would miss data the top of the final hour if the end
time was set to 1 second or less than the top of that final hour.
- Fix a concurrent modification issue where salt scanners were not synchronized on the
annotation map and could cause spinning threads.

- Version 2.2.1 (2016-10-08)
- Generate an incrementing TSMeta request only if both enable_tsuid_incrementing and
tsd.core.meta.enable_realtime_ts are enabled. Previously, increments would run
regardless of whether or not the real time ts setting was enabled. If tsuid
incrementing is disabled then a get and optional put is executed each time without
modifying the meta counter field.
