Clients use tokens which can be restricted to (read, write, deny) permissions using longest-prefix matches. * Watch mechanisms added to invoke a handler when data changes in consul. Used with the `consul watch` command, or by specifying `watches` in an agent configuration. * Event system added to support custom user events. Events are fired using the `consul event` command. They are handled using a standard watch. * Remote execution using `consul exec`. This allows for command execution on remote instances mediated through Consul. * RFC-2782 style DNS lookups supported * UI improvements, including support for ACLs. IMPROVEMENTS: * DNS case-insensitivity [GH-189] * Support for HTTP `?pretty` parameter to pretty format JSON output. * Use $SHELL when invoking handlers. [GH-237] * Agent takes the `-encrypt` CLI Flag [GH-245] * New `statsd_add` config for Statsd support.

[GH-162] * Key locking. KV data integrates with sessions to enable distributed locking. [GH-162] * DNS lookups can do stale reads and TTLs. [GH-200] * Added new /v1/agent/self endpoint [GH-173] * `reload` command can be used to trigger configuration reload from the CLI [GH-142] IMPROVEMENTS: * `members` has a much cleaner output format [GH-143] * `info` includes build version information * Sorted results for datacneter list [GH-198] * Switch multiplexing to yamux * Allow multiple CA certis in ca_file [GH-174] * Enable logging to syslog.

Importantly, the editor now allows editing keys with dashes in the name. [GH-119] * The web UI now has cancel and delete folder actions in the key/value editor. [GH-124], [GH-122] * Add flag to agent to write pid to a file. [GH-106] * Time out commands if Raft exceeds command enqueue timeout * Adding support for the `-advertise` CLI flag. [GH-156] * Fixing potential name conflicts on the WAN gossip ring [GH-158] * /v1/catalog/services returns an empty slice instead of null. [GH-145] * `members` command returns exit code 2 if no results. [GH-116] BUG FIXES: * Renaming "seperator" to "separator". This is the correct spelling, but both spellings are respected for backwards compatibility.

This is enabled by providing the `-ui-dir` flag with the path to the web directory. The UI is visited at the standard HTTP address (Defaults to http://127.0.0.1:8500/). There is a demo [available here](http://demo.consul.io). * Adding new read consistency modes. `?consistent` can be used for strongly consistent reads without caveats. `?stale` can be used for stale reads to allow for higher throughput and read scalability. [GH-68] * /v1/health/service/ endpoint can take an optional `?passing` flag to filter to only nodes with passing results. [GH-57] * The KV endpoint suports listing keys with the `?keys` query parameter, and limited up to a seperator using `?seperator=`. IMPROVEMENTS: * Health check output goes into seperate `Output` field instead of overriding `Notes`. [GH-59] * Adding a minimum check interval to prevent checks with extremely low intervals fork bombing. [GH-64] * Raft peer set cleared on leave. [GH-69] * Case insensitive parsing checks.
