Instead, the resulting + value will always be the latest value before the evaluation query timestamp. +* Regular expressions supplied via the configuration are now anchored to match + full strings instead of substrings. +* Global labels are not appended upon storing time series anymore. Instead, + they are only appended when communicating with external systems + (Alertmanager, remote storages, federation). +* The names and units of metrics related to remote storage sample appends have + been changed. +* The experimental support for writing to InfluxDB has been updated to work + with InfluxDB 0.9.x. 0.8.x versions of InfluxDB are not supported anymore. + +All changes: + +* [CHANGE] Vendoring is now done via govendor instead of godep. +* [CHANGE] Change web UI root page to show the graphing interface instead of + the server status page. +* [CHANGE] Append global labels only when communicating with external systems + instead of storing them locally. +* [CHANGE] Change all regexes in the configuration to do full-string matches + instead of substring matches. +* [CHANGE] Remove interpolation of vector values in queries. +* [CHANGE] For alert `SUMMARY`/`DESCRIPTION` template fields, cast the alert + value to `float64` to work with common templating functions. +* [CHANGE] In relabeling, don't include unmatched source label parts in the + replacement. +* [CHANGE] Change default full refresh interval for the file-based service + discovery from 30 seconds to 5 minutes. +* [CHANGE] Rename the DNS-SD meta label `__meta_dns_srv_name` to + `__meta_dns_name` to reflect support for other record types than `SRV`. +* [CHANGE] Release tarballs now contain the binaries in a nested directory. +* [CHANGE] Update InfluxDB write support to work with InfluxDB 0.9.x. +* [FEATURE] Allow configuring TLS options in scrape configurations. +* [FEATURE] Add instrumentation around configuration reloads. +* [FEATURE] Add `bool` modifier to comparison operators to enable boolean + (`0`/`1`) output instead of filtering. +* [FEATURE] In Zookeeper serverset discovery, provide `__meta_serverset_shard` + label with the serverset shard number. +* [FEATURE] Provide `__meta_consul_service_id` meta label in Consul service + discovery. +* [FEATURE] Allow scalar expressions in recording rules to enable use cases + such as building constant metrics. +* [FEATURE] Add `label_replace()` query language function. +* [FEATURE] In Consul service discovery, fill in the `__meta_consul_dc` + datacenter label from the Consul agent when it's not set in the Consul SD + config. +* [FEATURE] Scrape all services upon empty services list in Consul service + discovery. +* [FEATURE] Add `labelmap` relabeling action to map a set of input labels to a + set of output labels using regular expressions. +* [FEATURE] Introduce `__tmp` as a relabeling label prefix that is guaranteed + to not be used by Prometheus internally. +* [FEATURE] Kubernetes-based service discovery. +* [FEATURE] Marathon-based service discovery. +* [FEATURE] Support multiple series names in console graphs JavaScript library. +* [FEATURE] Allow reloading configuration via web handler at `/-/reload`. +* [FEATURE] Updates to promtool to reflect new Prometheus configuration + features. +* [FEATURE] Add `proxy_url` parameter to scrape configurations to enable use of + proxy servers. +* [FEATURE] Add console templates for Prometheus itself. +* [FEATURE] Allow relabeling the protocol scheme of targets. +* [FEATURE] Add `predict_linear()` query language function. +* [FEATURE] Support for authentication using bearer tokens, client certs, and + CA certs. +* [FEATURE] Implement unary expressions for vector types (`-foo`, `+foo`). +* [FEATURE] Add console templates for the SNMP exporter. +* [FEATURE] Make it possible to relabel target scrape query parameters. +* [FEATURE] Add support for `A` and `AAAA` records in DNS service discovery. +* [ENHANCEMENT] Update vendored dependencies. +* [ENHANCEMENT] Add compression to more HTTP handlers. +* [ENHANCEMENT] Make -web.external-url flag help string more verbose. +* [ENHANCEMENT] Improve metrics around remote storage queues. +* [ENHANCEMENT] Use Go 1.5.1 instead of Go 1.4.2 in builds. +* [ENHANCEMENT] Update the architecture diagram in the `README.md`. +* [ENHANCEMENT] Time out sample appends in retrieval layer if the storage is + backlogging. +* [ENHANCEMENT] Make `hash_mod` relabeling action use MD5 instead
