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.
