## 0.7.0 (UNRELEASED)
2016-07-01 19:42:20 +00:00
FEATURES:
* Added a new `/v1/txn` state store transaction API that allows for atomic
updates to and fetches from multiple entries in the key/value store. [GH-2028]
2016-08-09 18:43:57 +00:00
* Added a full replication capability for ACLs. Non-ACL datacenters can now
replicate the complete ACL set locally to their state store and fall back to
that if there's an outage. Additionally, this provides a good way to make a
backup ACL datacenter, or to migrate the ACL datacenter to a different one. [GH-2237]
2016-07-01 19:42:20 +00:00
* Script checks now support an optional `timeout` parameter. [GH-1762]
* Reap time for failed nodes is now configurable via new `reconnect_timeout` and
`reconnect_timeout_wan` config options ([use with caution](https://www.consul.io/docs/agent/options.html#reconnect_timeout)). [GH-1935]
* Consul agents can now limit the number of UDP answers returned via the DNS
interface. The default number of UDP answers is `3`, however by adjusting
the `dns_config.udp_answer_limit` configuration parameter, it is now
possible to limit the results down to `1`. This tunable provides
environments where RFC3484 section 6, rule 9 is enforced with an important
workaround in order to preserve the desired behavior of randomized DNS
results. Most modern environments will not need to adjust this setting as
this RFC was made obsolete by RFC 6724. See the
[agent options](https://www.consul.io/docs/agent/options.html#udp_answer_limit)
documentation for additional details for when this should be
used. [GH-1712]
2016-07-20 00:17:11 +00:00
* Prepared queries support baking in the `Near` sorting parameter. [GH-2137]
* Added Circonus support for telemetry. [GH-2193]
2016-07-22 17:42:17 +00:00
* Implemented a new set of feedback controls for the gossip layer that help
prevent degraded nodes that can't meet the soft real-time requirements from
erroneously causing `serfHealth` flapping in other, healthy nodes. [GH-2101]
2016-08-09 23:07:56 +00:00
* Upgraded to "stage one" of the v2 HashiCorp Raft library. This version offers
improved handling of cluster membership changes and recovery after a loss of
quorum. This version also provides a foundation for new features that will
2016-08-09 23:08:28 +00:00
appear in future Consul versions once the remainder of the v2 library is
complete. [GH-2222]
2016-07-01 19:42:20 +00:00
2016-04-13 04:40:32 +00:00
BACKWARDS INCOMPATIBILITIES:
* `skip_leave_on_interrupt`'s default behavior is now dependent on whether or
not the agent is acting as a server or client. When Consul is started as a
server the default is `true` and `false` when a client. [GH-1909]
2016-04-18 18:31:15 +00:00
* HTTP check output is truncated to 4k, similar to script check output. [GH-1952]
2016-08-02 21:03:45 +00:00
* Consul's Go API client will now send ACL tokens using HTTP headers instead of
query parameters, requiring Consul 0.6.0 or later. [GH-2233]
2016-08-10 01:26:18 +00:00
* Removed support for protocol version 1, so Consul 0.7 is no longer compatible
with Consul versions prior to 0.3. [GH-2259]
2016-04-13 04:40:32 +00:00
IMPROVEMENTS:
2016-07-11 23:37:57 +00:00
* Consul will now retry RPC calls that result in "no leader" errors for up to
5 seconds. This allows agents to ride out leader elections with a delayed
response vs. an error. [GH-2175]
2016-06-28 16:13:36 +00:00
* Joins based on a DNS lookup will use TCP and attempt to join with the full
list of returned addresses. [GH-2101]
* Added a new network tomogroaphy visualization to the UI. [GH-2046]
* Consul agents will now periodically reconnect to available Consul servers
in order to redistribute their RPC query load. Consul clients will, by
default, attempt to establish a new connection every 120s to 180s unless
the size of the cluster is sufficiently large. The rate at which agents
begin to query new servers is proportional to the size of the Consul
cluster (servers should never receive more than 64 new connections per
second per Consul server as a result of rebalancing). Clusters in stable
environments who use `allow_stale` should see a more even distribution of
query load across all of their Consul servers. [GH-1743]
2016-04-13 04:40:32 +00:00
* Consul will now refuse to start with a helpful message if the same UNIX
socket is used for more than one listening endpoint. [GH-1910]
* Removed an obsolete warning message when Consul starts on Windows. [GH-1920]
* Defaults bind address to 127.0.0.1 when running in `-dev` mode. [GH-1878]
2016-04-20 20:53:18 +00:00
* HTTP health checks limit saved output to 4K to avoid performance issues. [GH-1952]
2016-07-20 00:17:11 +00:00
* Added version information to the log when Consul starts up. [GH-1404]
2016-08-09 23:04:37 +00:00
* Added timing metrics for HTTP requests. [GH-2256]
2016-08-10 00:51:00 +00:00
* Updated all vendored dependencies. [GH-2258]
2016-08-10 01:34:01 +00:00
* Builds Consul releases with Go 1.6.3. [GH-2260]
2016-04-13 04:40:32 +00:00
BUG FIXES:
2016-06-28 16:08:31 +00:00
* Fixed a deadlock releated to sorting the list of available datacenters by round trip
time. [GH-2130]
2016-06-09 02:33:24 +00:00
* Fixed an issue with the state store's immutable radix tree that would prevent it
from using cached modified objects during transactions, leading to extra copies
and increased memory / GC pressure. [GH-2106]
2016-04-13 04:40:32 +00:00
* Fixed an issue where a health check's output never updates if the check
status doesn't change after the Consul agent starts. [GH-1934]
2016-05-24 19:50:48 +00:00
* External services can now be registered with ACL tokens. [GH-1738]
2016-07-25 23:32:43 +00:00
* Upgraded Bolt DB to v1.2.1 to fix an issue on Windows where Consul would sometimes
2016-08-09 02:03:20 +00:00
fail to start due to open user-mapped sections. [GH-2203]
* Fixed an issue where large events affecting many nodes could cause infinite intent
rebroadcasts, leading to many log messages about intent queue overflows. [GH-1062]
OTHER CHANGES:
* Switched from Godep to govendor. [GH-2252]
2016-03-16 16:42:07 +00:00
## 0.6.4 (March 16, 2016)
BACKWARDS INCOMPATIBILITIES:
2016-03-05 00:37:35 +00:00
* Added a new `query` ACL type to manage prepared query names, and stopped capturing
ACL tokens by default when prepared queries are created. This won't affect existing
queries and how they are executed, but this will affect how they are managed. Now
management of prepared queries can be delegated within an organization. If you use
prepared queries, you'll need to read the
[Consul 0.6.4 upgrade instructions](https://www.consul.io/docs/upgrade-specific.html)
before upgrading to this version of Consul. [GH-1748]
2016-03-10 21:22:31 +00:00
* Consul's Go API client now pools connections by default, and requires you to manually
opt-out of this behavior. Previously, idle connections were supported and their
lifetime was managed by a finalizer, but this wasn't reliable in certain situations.
If you reuse an API client object during the lifetime of your application, then there's
nothing to do. If you have short-lived API client objects, you may need to configure them
using the new `api.DefaultNonPooledConfig()` method to avoid leaking idle connections. [GH-1825]
2016-03-05 00:37:35 +00:00
* Consul's Go API client's `agent.UpdateTTL()` function was updated in a way that will
only work with Consul 0.6.4 and later. The `agent.PassTTL()`, `agent.WarnTTL()`, and
`agent.FailTTL()` functions were not affected and will continue work with older
versions of Consul. [GH-1794]
2016-03-11 01:02:26 +00:00
FEATURES:
2016-03-07 21:38:20 +00:00
* Added new template prepared queries which allow you to define a prefix (possibly even
an empty prefix) to apply prepared query features like datacenter failover to multiple
services with a single query definition. This makes it easy to apply a common policy to
2016-03-10 21:33:16 +00:00
multiple services without having to manage many prepared queries. See
[Prepared Query Templates](https://www.consul.io/docs/agent/http/query.html#templates)
for more details. [GH-1764]
2016-02-07 22:30:30 +00:00
* Added a new ability to translate address lookups when doing queries of nodes in
remote datacenters via DNS using a new `translate_wan_addrs` configuration
option. This allows the node to be reached within its own datacenter using its
local address, and reached from other datacenters using its WAN address, which is
useful in hybrid setups with mixed networks. [GH-1698]
2016-03-11 01:02:26 +00:00
IMPROVEMENTS:
* Added a new `disable_hostname` configuration option to control whether Consul's
runtime telemetry gets prepended with the host name. All of the telemetry
configuration has also been moved to a `telemetry` nested structure, but the old
format is currently still supported. [GH-1284]
2016-03-05 00:37:35 +00:00
* Consul's Go dependencies are now vendored using Godep. [GH-1714]
* Added support for `EnableTagOverride` for the catalog in the Go API client. [GH-1726]
* Consul now ships built from Go 1.6. [GH-1735]
* Added a new `/v1/agent/check/update/<check id>` API for updating TTL checks which
makes it easier to send large check output as part of a PUT body and not a query
parameter. [GH-1785].
2016-03-10 20:36:54 +00:00
* Added a default set of `Accept` headers for HTTP checks. [GH-1819]
2016-03-10 20:37:41 +00:00
* Added support for RHEL7/Systemd in Terraform example. [GH-1629]
BUG FIXES:
2016-03-05 00:37:35 +00:00
* Updated the internal web UI (`-ui` option) to latest released build, fixing
an ACL-related issue and the broken settings icon. [GH-1619]
2016-01-21 00:59:46 +00:00
* Fixed an issue where blocking KV reads could miss updates and return stale data
2016-03-05 00:37:35 +00:00
when another key whose name is a prefix of the watched key was updated. [GH-1632]
* Fixed the redirect from `/` to `/ui` when the internal web UI (`-ui` option) is
enabled. [GH-1713]
2016-03-10 23:11:48 +00:00
* Updated memberlist to pull in a fix for leaking goroutines when performing TCP
fallback pings. This affected users with frequent UDP connectivity problems. [GH-1802]
2016-03-09 18:52:04 +00:00
* Added a fix to trim UDP DNS responses so they don't exceed 512 bytes. [GH-1813]
2016-03-09 21:34:07 +00:00
* Updated go-dockerclient to fix Docker health checks with Docker 1.10. [GH-1706]
2016-01-21 00:59:46 +00:00
2016-01-15 16:17:42 +00:00
## 0.6.3 (January 15, 2016)
BUG FIXES:
* Fixed an issue when running Consul as PID 1 in a Docker container where
it could consume CPU and show spurious failures for health checks, watch
handlers, and `consul exec` commands [GH-1592]
2016-01-15 16:17:42 +00:00
## 0.6.2 (January 13, 2016)
SECURITY:
* Build against Go 1.5.3 to mitigate a security vulnerability introduced
in Go 1.5. For more information, please see https://groups.google.com/forum/#!topic/golang-dev/MEATuOi_ei4
This is a security-only release; other than the version number and building
against Go 1.5.3, there are no changes from 0.6.1.
2016-01-15 16:17:42 +00:00
## 0.6.1 (January 6, 2016)
2015-12-17 06:43:05 +00:00
BACKWARDS INCOMPATIBILITIES:
* The new `-monitor-retry` option to `consul lock` defaults to 3. This
will cause the lock monitor to retry up to 3 times, waiting 1s between
each attempt if it gets a 500 error from the Consul servers. For the
vast majority of use cases this is desirable to prevent the lock from
being given up during a brief period of Consul unavailability. If you
want to get the previous default behavior you will need to set the
2016-01-07 02:15:09 +00:00
`-monitor-retry=0` option.
2015-12-17 06:43:05 +00:00
IMPROVEMENTS:
* Consul is now built with Go 1.5.2
* Added source IP address and port information to RPC-related log error
2016-01-06 05:18:56 +00:00
messages and HTTP access logs [GH-1513] [GH-1448]
* API clients configured for insecure SSL now use an HTTP transport that's
set up the same way as the Go default transport [GH-1526]
2016-02-02 19:38:28 +00:00
* Added new per-host telemetry on DNS requests [GH-1537]
2016-01-06 05:18:56 +00:00
* Added support for reaping child processes which is useful when running
Consul as PID 1 in Docker containers [GH-1539]
* Added new `-ui` command line and `ui` config option that enables a built-in
Consul web UI, making deployment much simpler [GH-1543]
* Added new `-dev` command line option that creates a completely in-memory
standalone Consul server for development
* Added a Solaris build, now that dependencies have been updated to support
it [GH-1568]
* Added new `-try` option to `consul lock` to allow it to timeout with an error
if it doesn't acquire the lock [GH-1567]
* Added a new `-monitor-retry` option to `consul lock` to help ride out brief
periods of Consul unavailabily without causing the lock to be given up [GH-1567]
2015-12-17 06:43:05 +00:00
BUG FIXES:
* Fixed broken settings icon in web UI [GH-1469]
* Fixed a web UI bug where the supplied token wasn't being passed into
the internal endpoint, breaking some pages when multiple datacenters
were present [GH-1071]
## 0.6.0 (December 3, 2015)
2015-06-02 22:08:48 +00:00
BACKWARDS INCOMPATIBILITIES:
* A KV lock acquisition operation will now allow the lock holder to
2015-11-13 18:08:57 +00:00
update the key's contents without giving up the lock by doing another
PUT with `?acquire=<session>` and providing the same session that
is holding the lock. Previously, this operation would fail.
2015-06-12 17:40:51 +00:00
FEATURES:
* Service ACLs now apply to service discovery [GH-1024]
* Added event ACLs to guard firing user events [GH-1046]
* Added keyring ACLs for gossip encryption keyring operations [GH-1090]
2015-12-21 19:36:38 +00:00
* Added a new TCP check type that does a connect as a check [GH-1130]
* Added new "tag override" feature that lets catalog updates to a
service's tags flow down to agents [GH-1187]
* Ported in-memory database from LMDB to an immutable radix tree to improve
read throughput, reduce garbage collection pressure, and make Consul 100%
pure Go [GH-1291]
2015-11-13 17:58:30 +00:00
* Added support for sending telemetry to DogStatsD [GH-1293]
* Added new network tomography subsystem that estimates the network
round trip times between nodes and exposes that in raw APIs, as well
as in existing APIs (find the service node nearest node X); also
includes a new `consul rtt` command to query interactively [GH-1331]
* Consul now builds under Go 1.5.1 by default [GH-1345]
* Added built-in support for running health checks inside Docker containers
[GH-1343]
2015-11-14 20:49:35 +00:00
* Added prepared queries which support service health queries with rich
features such as filters for multiple tags and failover to remote datacenters
based on network coordinates; these are available via HTTP as well as the
DNS interface [GH-1389]
2015-06-12 17:40:51 +00:00
2015-06-02 22:08:48 +00:00
BUG FIXES:
2015-12-01 18:34:52 +00:00
* Fixed expired certificates in unit tests [GH-979]
2015-06-02 22:08:48 +00:00
* Allow services with `/` characters in the UI [GH-988]
* Added SOA/NXDOMAIN records to negative DNS responses per RFC2308 [GH-995]
[GH-1142] [GH-1195] [GH-1217]
2015-06-12 17:40:51 +00:00
* Token hiding in HTTP logs bug fixed [GH-1020]

* Fixed reverse DNS lookups to recursor [GH-1137]
* Removes the trailing `/` added by the `consul lock` command [GH-1145]
* Fixed bad lock handler execution during shutdown [GH-1080] [GH-1158] [GH-1214]
* Added missing support for AAAA queries for nodes [GH-1222]
2015-09-10 19:31:13 +00:00
* Tokens passed from the CLI or API work for maint mode [GH-1230]
2016-02-02 19:38:28 +00:00
* Fixed service deregister/reregister flaps that could happen during
`consul reload` [GH-1235]
* Fixed the Go API client to properly distinguish between expired sessions
and sessions that don't exist [GH-1041]
* Fixed the KV section of the UI to work on Safari [GH-1321]
2016-02-02 19:38:28 +00:00
* Cleaned up JavaScript for built-in UI with bug fixes [GH-1338]
2015-06-02 22:08:48 +00:00
2015-06-23 19:34:53 +00:00
IMPROVEMENTS:
* Added sorting of `consul members` command output [GH-969]
* Updated AWS templates for RHEL6, CentOS6 [GH-992] [GH-1002]
2015-06-23 19:34:53 +00:00
* Advertised gossip/rpc addresses can now be configured [GH-1004]
* Failed lock acquisition handling now responds based on type of failure
[GH-1006]
* Agents now remember check state across restarts [GH-1009]
* Always run ACL tests by default in API tests [GH-1030]
* Consul now refuses to start if there are multiple private IPs [GH-1099]
* Improved efficiency of servers managing incoming connections from agents
[GH-1170]
* Added logging of the DNS client addresses in error messages [GH-1166]
* Added `-http-port` option to change the HTTP API port number [GH-1167]
2015-08-27 20:35:24 +00:00
* Atlas integration options are reload-able via SIGHUP [GH-1199]
* Atlas endpoint is a configurable option and CLI arg [GH-1201]
* Added `-pass-stdin` option to `consul lock` command [GH-1200]
* Enables the `/v1/internal/ui/*` endpoints, even if `-ui-dir` isn't set
[GH-1215]
* Added HTTP method to Consul's log output for better debugging [GH-1270]
2015-11-13 18:08:57 +00:00
* Lock holders can `?acquire=<session>` a key again with the same session
that holds the lock to update a key's contents without releasing the
lock [GH-1291]
* Improved an O(n^2) algorithm in the agent's catalog sync code [GH-1296]
2015-10-15 22:00:41 +00:00
* Switched to net-rpc-msgpackrpc to reduce RPC overhead [GH-1307]
2015-11-17 19:42:24 +00:00
* Removed all uses of the http package's default client and transport in
Consul to avoid conflicts with other packages [GH-1310] [GH-1327]
2015-11-17 19:42:24 +00:00
* Added new `X-Consul-Token` HTTP header option to avoid passing tokens
in the query string [GH-1318]
2015-11-17 19:42:24 +00:00
* Increased session TTL max to 24 hours (use with caution, see note added
to the Session HTTP endpoint documentation) [GH-1412]
2015-12-01 06:11:20 +00:00
* Added support to the API client for retrying lock monitoring when Consul
is unavailable, helping prevent false indications of lost locks (eg. apps
like Vault can avoid failing over when a Consul leader election occurs)
[GH-1457]
2015-12-01 16:31:15 +00:00
* Added reap of receive buffer space for idle streams in the connection
pool [GH-1452]
2015-06-23 19:34:53 +00:00
2015-06-04 07:04:44 +00:00
MISC:
* Lots of docs fixes
* Lots of Vagrantfile cleanup
2015-12-01 06:12:39 +00:00
* Data migrator utility removed to eliminate cgo dependency [GH-1309]
2015-06-04 07:04:44 +00:00
2015-10-15 21:52:58 +00:00
UPGRADE NOTES:
* Consul will refuse to start if the data directory contains an "mdb" folder.
This folder was used in versions of Consul up to 0.5.1. Consul version 0.5.2
included a baked-in utility to automatically upgrade the data format, but
2015-12-01 06:12:39 +00:00
this has been removed in Consul 0.6 to eliminate the dependency on cgo.
* New service read, event firing, and keyring ACLs may require special steps to
perform during an upgrade if ACLs are enabled and set to deny by default.
* Consul will refuse to start if there are multiple private IPs available, so
if this is the case you will need to configure Consul's advertise or bind
addresses before upgrading.
See https://www.consul.io/docs/upgrade-specific.html for detailed upgrade
instructions.

## 0.5.0 (February 19, 2015)
2015-01-22 21:30:37 +00:00
FEATURES:
* Key rotation support for gossip layer. This allows the `encrypt` key
to be changed globally. See "keyring" command. [GH-336]
* Options to join the WAN pool on start (`start_join_wan`, `retry_join_wan`) [GH-477]
* Optional HTTPS interface [GH-478]
* Ephemeral keys via "delete" session behavior. This allows keys to be deleted when
a session is invalidated instead of having the lock released. Adds new "Behavior"
field to Session which is configurable. [GH-487]
* Reverse DNS lookups via PTR for IPv4 and IPv6 [GH-475]
* API added checks and services are persisted. This means services and
checks will survive a crash or restart. [GH-497]
* ACLs can now protect service registration. Users in blacklist mode should
allow registrations before upgrading to prevent a service disruption. [GH-506] [GH-465]
* Sessions support a heartbeat failure detector via use of TTLs. This adds a new
"TTL" field to Sessions and a `/v1/session/renew` endpoint. Heartbeats act like a
failure detector (health check), but are managed by the servers. [GH-524] [GH-172]
* Support for service specific IP addresses. This allows the service to advertise an
address that is different from the agent. [GH-229] [GH-570]
* Support KV Delete with Check-And-Set [GH-589]
* Merge `armon/consul-api` into `api` as official Go client.

2015-01-22 21:30:37 +00:00
* Added new "consul lock" command for simple highly-available deployments.
This lets Consul manage the leader election and easily handle N+1 deployments
without the applications being Consul aware. [GH-619]
* Multiple checks can be associated with a service [GH-591] [GH-230]
BUG FIXES:
* Fixed X-Consul-Index calculation for KV ListKeys

* Added support for defining multiple services per configuration file [GH-433]
* Added support for defining multiple checks per configuration file [GH-433]
2015-01-22 21:30:37 +00:00
* Allow mixing of service and check definitions in a configuration file [GH-433]
* Allow notes for checks in service definition file [GH-449]
* Random stagger for agent checks to prevent thundering herd [GH-546]
* More useful metrics are sent to statsd/statsite

* Many documentation improvements
* Reduce log messages when quorum member is logs [GH-566]
2015-01-25 21:59:30 +00:00
UPGRADE NOTES:
* If `acl_default_policy` is "deny", ensure tokens are updated to enable
service registration to avoid a service disruption. The new ACL policy
can be submitted with 0.4 before upgrading to 0.5 where it will be
enforced.
* Servers running 0.5.X cannot be mixed with older servers. (Any client
version is fine). There is a 15 minute upgrade window where mixed
versions are allowed before older servers will panic due to an unsupported
internal command. This is due to the new KV tombstones which are internal
to servers.
