2.6 KiB

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.
