OpenTSDB v1.1.0 has been released!

[tsuna]

After 2 RCs that took seemingly forever, here it is.

This the second official release, and with development effort now
picking up, I expect we'll see more frequent releases moving forward.
This release contains a lot of bug fixes and a number of improvements.

Noteworthy changes:
- Licensing adjustment: allow LGPLv2.1+ in addition to LGPLv3+.
- Various fixes used when customizing size of UniqueId. The default size
is 3 bytes and is a compile-time constant rarely changed in practice.

- New `fgcolor', `bgcolor' and `smooth' query parameters to /q.
- New `tz' query string parameter to allow specifying a custom time zone.
- Stop accepting connections when shutting down.
- A new `dropcaches' administrative command allows discarding in-memory
caches. Right now these are UID mappings.
- Browser history support in the web UI.
- Allow "1d-ago" style input in date boxes.
- Fix the 30d integer overflow in the web UI.
- Add the ability to use mouse for drag-to-zoom on graphs.
- Integration with Maven.
- Work around a Netty performance bug, increasing write throughput by 10x.
- Properly parse floating point values in scientific notations.
- Allow tuning the number of worker threads or using OIO.
- Fix auto-completion bug causing partial results to show in the web UI.
- Various internal bug fixes.
- Update all dependencies.
- TSDB data compaction is now enabled by default.

Is there any plan to implement issue # 70 (Add a &exact query string parameter to precisely respect the start/end dates) ?

We'll definitely have something like it in 2.0 and maybe we can get it into a 1.2 release if there is enough demand.

A better solution than an &exact hack would be to just filter out
excess data until we get the first data point with a timestamp <=
start_date and one with timestamp >= end_date.

Right, but we still need padding for the Gnuplot graphs right? So I figure we could make the new api/vX calls exact by default and leave the Gnuplot query with padding. Should work for everyone.

No the idea is to still look for extra data, but only get one data
point before the start date requested, and one after. That's all
that's needed to plot correct graphs too.
