1.1.0

[JLockerman]

This release contains new experimental features and bugfixes.

Experimental Features

• hyperloglog has been updated to use Hyperloglog++ under the hood. This does not change the user-facing API but should improve the accuracy of hyperloglog() estimates. This is the last major change expected for hyperloglog() and the candidate is now a candidate for stabilization pending user feedback.
• We've started experimenting with the pipeline API. While it's still very much a work in progress, it's at a point where the high-level concepts should be understandable. For example, a pipeline that outputs the daily change of a set of data, interpolating away any gaps in the original data, could look like

  SELECT timeseries(time, val)
      |> sort()
      |> fill_holes('interpolate')
      |> resample_to_rate('trailing_average', '24 hours', true)
      |> delta()
  FROM ...

  It's still early days for this API and it is not yet polished, but we would love feedback about its direction.

Bugfixes

• Fixed a small memory leak in aggregation functions. This could have leaked ≈8 bytes per aggregate call.
