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).

[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.

[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.

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