Changes by Version
==================

2.20.0 (2019-11-06)
-------------------

## New Features

- Allow all in-process spans of a trace to share sampling state (#443) -- Prithvi Raj

  Sampling state is shared between all spans of the trace that are still in memory.
  This allows implementation of delayed sampling decisions (see below).

- Support delayed sampling decisions (#449) -- Yuri Shkuro

  This is a large structural change to how the samplers work.
  It allows some samplers to be executed multiple times on different
  span events (like setting a tag) and make a positive sampling decision
  later in the span life cycle, or even based on children spans.
  See [README](./README.md#delayed-sampling) for more details.

  There is a related minor change in behavior of the adaptive (per-operation) sampler,
  which will no longer re-sample the trace when `span.SetOperation()` is called, i.e. the
  operation used to make the sampling decision is always the one provided at span creation.

- Add experimental tag matching sampler (#452) -- Yuri Shkuro

  A sampler that can sample a trace based on a certain tag added to the root
  span or one of its local (in-process) children. The sampler can be used with
  another experimental `PrioritySampler` that allows multiple samplers to try
  to make a sampling decision, in a certain priority order.
