0.8.0 / 2016-08-17

• [CHANGE] Registry is doing more consistency checks. This might break existing setups that used to export inconsistent metrics.
• [CHANGE] Pushing to Pushgateway moved to package push and changed to allow arbitrary grouping.
• [CHANGE] Removed SelfCollector.
• [CHANGE] Removed PanicOnCollectError and EnableCollectChecks methods.
• [CHANGE] Moved packages to the prometheus/common repo: text, model, extraction.
• [CHANGE] Deprecated a number of functions.
• [FEATURE] Allow custom registries. Added Registerer and Gatherer interfaces.
• [FEATURE] Separated HTTP exposition, allowing custom HTTP handlers (package promhttp) and enabling the creation of other exposition mechanisms.
• [FEATURE] MustRegister is variadic now, allowing registration of many collectors in one call.
• [FEATURE] Added HTTP API v1 package.
• [ENHANCEMENT] Numerous documentation improvements.
• [ENHANCEMENT] Improved metric sorting.
• [ENHANCEMENT] Inlined fnv64a hashing for improved performance.
• [ENHANCEMENT] Several test improvements.
• [BUGFIX] Handle collisions in MetricVec.

0.7.0 / 2015-07-27

• [CHANGE] Rename ExporterLabelPrefix to ExportedLabelPrefix.
• [BUGFIX] Closed gaps in metric consistency check.
• [BUGFIX] Validate LabelName/LabelSet on JSON unmarshaling.
• [ENHANCEMENT] Document the possibility to create "empty" metrics in a metric vector.
• [ENHANCEMENT] Fix and clarify various doc comments and the README.md.
• ENHANCEMENT solve "The Proxy Problem" of http.InstrumentHandler.
• [ENHANCEMENT] Change responseWriterDelegator.written to int64.

0.6.0 / 2015-06-01

• [CHANGE] Rename process_goroutines to go_goroutines.
• [ENHANCEMENT] Validate label names during YAML decoding.
• [ENHANCEMENT] Add LabelName regular expression.
• [BUGFIX] Ensure alignment of struct members for 32-bit systems.

0.5.0 / 2015-05-06

• [BUGFIX] Removed a weakness in the fingerprinting aka signature code. This makes fingerprinting slower and more allocation-heavy, but the weakness was too severe to be tolerated.
• [CHANGE] As a result of the above, Metric.Fingerprint is now returning a different fingerprint. To keep the same fingerprint, the new method Metric.FastFingerprint was introduced, which will be used by the Prometheus server for storage purposes (implying that a collision detection has to be added, too).
• [ENHANCEMENT] The Metric.Equal and Metric.Before do not depend on fingerprinting anymore, removing the possibility of an undetected fingerprint collision.
• [FEATURE] The Go collector in the exposition library includes garbage collection stats.
• [FEATURE] The exposition library allows to create constant "throw-away" summaries and histograms.
• [CHANGE] A number of new reserved labels and prefixes.

0.4.0 / 2015-04-08

• [CHANGE] Return NaN when Summaries have no observations yet.
• [BUGFIX] Properly handle Summary decay upon Write().
• [BUGFIX] Fix the documentation link to the consumption library.
• [FEATURE] Allow the metric family injection hook to merge with existing metric families.
• [ENHANCEMENT] Removed cgo dependency and conditional compilation of procfs.
• [MAINTENANCE] Adjusted to changes in matttproud/golang_protobuf_extensions.

0.3.2 / 2015-03-11

• [BUGFIX] Fixed the receiver type of COWMetric.Set(). This method is only used by the Prometheus server internally.
• [CLEANUP] Added licenses of vendored code left out by godep.

0.3.1 / 2015-03-04

• [ENHANCEMENT] Switched fingerprinting functions from own free list to sync.Pool.
• [CHANGE] Makefile uses Go 1.4.2 now (only relevant for examples and tests).

0.3.0 / 2015-03-03

• [CHANGE] Changed the fingerprinting for metrics. THIS WILL INVALIDATE ALL PERSISTED FINGERPRINTS. IF YOU COMPILE THE PROMETHEUS SERVER WITH THIS VERSION, YOU HAVE TO WIPE THE PREVIOUSLY CREATED STORAGE.
• [CHANGE] LabelValuesToSignature removed. (Nobody had used it, and it was arguably broken.)
• [CHANGE] Vendored dependencies. Those are only used by the Makefile. If client_golang is used as a library, the vendoring will stay out of your way.
• [BUGFIX] Remove a weakness in the fingerprinting for metrics. (This made the fingerprinting change above necessary.)
• [FEATURE] Added new fingerprinting functions SignatureForLabels and SignatureWithoutLabels to be used by the Prometheus server. These functions require fewer allocations than the ones currently used by the server.

0.2.0 / 2015-02-23

• [FEATURE] Introduce new Histagram metric type.
• [CHANGE] Ignore process collector errors for now (better error handling pending).
• [CHANGE] Use clear error interface for process pidFn.
• [BUGFIX] Fix Go download links for several archs and OSes.
• [ENHANCEMENT] Massively improve Gauge and Counter performance.
• [ENHANCEMENT] Catch illegal label names for summaries in histograms.
• [ENHANCEMENT] Reduce allocations during fingerprinting.
• [ENHANCEMENT] Remove cgo dependency. procfs package will only be included if both cgo is available and the build is for an OS with procfs.
• [CLEANUP] Clean up code style issues.
• [CLEANUP] Mark slow test as such and exclude them from travis.
• [CLEANUP] Update protobuf library package name.
• [CLEANUP] Updated vendoring of beorn7/perks.

0.1.0 / 2015-02-02

• [CLEANUP] Introduced semantic versioning and changelog. From now on, changes will be reported in this file.
