## 0.7.0 (UNRELEASED)
|
|
|
|
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]
|
|
* 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]
|
|
* 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]
|
|
* Prepared queries support baking in the `Near` sorting parameter. [GH-2137]
|
|
* Added Circonus support for telemetry. [GH-2193]
|
|
* 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]
|
|
* 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
|
|
appear in future Consul versions once the remainder of the v2 library is
|
|
complete. [GH-2222]
|
|
|
|
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]
|
|
* HTTP check output is truncated to 4k, similar to script check output. [GH-1952]
|
|
* 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]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* 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]
|
|
* 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]
|
|
* 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]
|
|
* Builds Consul releases with Go 1.6.1. [GH-1948]
|
|
* HTTP health checks limit saved output to 4K to avoid performance issues. [GH-1952]
|
|
* Added version information to the log when Consul starts up. [GH-1404]
|
|
* Added timing metrics for HTTP requests. [GH-2256]
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed a deadlock releated to sorting the list of available datacenters by round trip
|
|
time. [GH-2130]
|
|
* 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]
|
|
* 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]
|
|
* External services can now be registered with ACL tokens. [GH-1738]
|
|
* Upgraded Bolt DB to v1.2.1 to fix an issue on Windows where Consul would sometimes
|
|
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]
|
|
|
|
## 0.6.4 (March 16, 2016)
|
|
|
|
BACKWARDS INCOMPATIBILITIES:
|
|
|
|
* 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]
|
|
* 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]
|
|
* 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]
|
|
|
|
FEATURES:
|
|
|
|
* 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
|
|
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]
|
|
* 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]
|
|
|
|
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]
|
|
* 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].
|
|
* Added a default set of `Accept` headers for HTTP checks. [GH-1819]
|
|
* Added support for RHEL7/Systemd in Terraform example. [GH-1629]
|
|
|
|
BUG FIXES:
|
|
|
|
* Updated the internal web UI (`-ui` option) to latest released build, fixing
|
|
an ACL-related issue and the broken settings icon. [GH-1619]
|
|
* Fixed an issue where blocking KV reads could miss updates and return stale data
|
|
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]
|
|
* 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]
|
|
* Added a fix to trim UDP DNS responses so they don't exceed 512 bytes. [GH-1813]
|
|
* Updated go-dockerclient to fix Docker health checks with Docker 1.10. [GH-1706]
|
|
|
|
## 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]
|
|
|
|
## 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.
|
|
|
|
## 0.6.1 (January 6, 2016)
|
|
|
|
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
|
|
`-monitor-retry=0` option.
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* Consul is now built with Go 1.5.2
|
|
* Added source IP address and port information to RPC-related log error
|
|
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]
|
|
* Added new per-host telemetry on DNS requests [GH-1537]
|
|
* 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]
|
|
|
|
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)
|
|
|
|
BACKWARDS INCOMPATIBILITIES:
|
|
|
|
* A KV lock acquisition operation will now allow the lock holder to
|
|
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.
|
|
|
|
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]
|
|
* 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]
|
|
* 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]
|
|
* 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]
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed expired certificates in unit tests [GH-979]
|
|
* 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]
|
|
* Token hiding in HTTP logs bug fixed [GH-1020]
|
|
* RFC6598 addresses are accepted as private IPs [GH-1050]
|
|
* 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]
|
|
* Tokens passed from the CLI or API work for maint mode [GH-1230]
|
|
* 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]
|
|
* Cleaned up JavaScript for built-in UI with bug fixes [GH-1338]
|
|
|
|
IMPROVEMENTS:
|
|
|
|
* Added sorting of `consul members` command output [GH-969]
|
|
* Updated AWS templates for RHEL6, CentOS6 [GH-992] [GH-1002]
|
|
* 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]
|
|
* 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]
|
|
* 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]
|
|
* Switched to net-rpc-msgpackrpc to reduce RPC overhead [GH-1307]
|
|
* Removed all uses of the http package's default client and transport in
|
|
Consul to avoid conflicts with other packages [GH-1310] [GH-1327]
|
|
* Added new `X-Consul-Token` HTTP header option to avoid passing tokens
|
|
in the query string [GH-1318]
|
|
* Increased session TTL max to 24 hours (use with caution, see note added
|
|
to the Session HTTP endpoint documentation) [GH-1412]
|
|
* 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]
|
|
* Added reap of receive buffer space for idle streams in the connection
|
|
pool [GH-1452]
|
|
|
|
MISC:
|
|
|
|
* Lots of docs fixes
|
|
* Lots of Vagrantfile cleanup
|
|
* Data migrator utility removed to eliminate cgo dependency [GH-1309]
|
|
|
|
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
|
|
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)
|
|
|
|
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

|
field to Session which is configurable. [GH-487]
|
|
* Reverse DNS lookups via PTR for IPv4 and IPv6 [GH-475]
|

|
|
* 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]

|
|
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]
|
|

|
|
|
|
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.
|
|
|
|

|
|
|
|
FEATURES:

|
|
|
* Fine-grained ACL system to restrict access to KV store. Clients
|
|
use tokens which can be restricted to (read, write, deny) permissions
|
|
using longest-prefix matches.

|
|
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.

|
|
instances mediated through Consul.

|
|
DNS, HTTP, or RPC endpoints. [GH-301] [GH-253]
|
|
* Support [Checkpoint](http://checkpoint.hashicorp.com) for security bulletins
|
|
and update announcements.
|
|
|
|
BUG FIXES:
|
|
|
|
* Fixed race condition in `-bootstrap-expect` [GH-254]
|
|
* Require PUT to /v1/session/destroy [GH-285]
|
|
* Fixed registration race condition [GH-300] [GH-279]
|
|
|
|
UPGRADE NOTES:
|
|
|
|
* ACL support should not be enabled until all server nodes are running
|
|
Consul 0.4. Mixed server versions with ACL support enabled may result in
|
|
panics.
