v2.1.3: Stable v2 api

This release constitutes a stabilization of the v2 api.

v0.4.0: Small updates for Consul v1.5.0

This release includes:

• Setting minimum consul version to v1.5.0
  • Updating go.mod, Gopkg.toml, and glide.yaml files accordingly
• Bugfix in SiblingLocator that passed the token in for the datacenter and vice versa
• Updating travis to use consul v1.5.0

v0.3.2: Candidate Shutdown

This release addresses an issue where a Candidate would attempt to restart its underlying Session after resignation.

v0.3.1: Watch Plans

• Adding the various connect_* watch plans to the provided helpers
• Adding *Handler and *HybridHandler helper funcs for each plan type
• Bumping minimum required Consul to 1.2.0

v0.3.0: Candidate and Session improvements

Session:

• Adding "watchers" concept to session package so it is more useful as
    a standalone package
• Using RWMutex on session.Session over basic Mutex
• Breaking up Session::maintain() loop into separate funcs

Candidate:

• Using RWMutex on candidate.Candidate over basic Mutex
• Sessions are now only created once the Candidate has been told to
    enter election pool
• Candidate::Run() now returns an error if the session was unable to be
    created
• No longer using a channel to handle session updates
• Breaking up Candidate::lockRunner() into separate funcs
• A session update no longer directly sends a watcher update, instead
    executing a Candidate::refreshLock() call.

v0.2.3: Bugfixes and Features

• Eliminated a few race conditions made present in previous updates
• Added "AutoRun" concept to both Session and Candidate
• Candidate.WaitX() methods will now return an error if called
  on a candidate that is not actively in the running
• Moved the old Candidate tests to the candidate package and
  updated them appropriately
• Added some more logging at key parts of the session and candidate
  keepalive loops
• Severely reducing the complexity of the Candidate keepalive loop
• Session will now attempt to actively destroy the upstream session
  if the state goes out of whack (generally due to timeout)
• Normal session "update" calls no longer block (may want to add
  unecessary complexity to this later...)
• Session.Stop() now returns an error, which if not nil can
  probably be ignored most of the time

v0.2.1: Candidate Improvements

Created 2 new sub-packages

• candidate
• session

Session

The new session package provides a way to manage the creation and maintenance of a persistent session in Consul. It is primarily designed to be used with the candidate package, but can be used on its own.

Candidate

The new candidate package provides the same functionality as the old package, but adds better resiliency in the event that a session is yanked out from under it in Consul, and is re-usable. You may call .Resign() and then .Run() successively if your app's workflow necessitates that.

This release has no breaking changes.
