prometheus (2.13.1+ds-1) unstable; urgency=medium

  This release removes Azure support, as it is a fast moving target, and the
  Debian packaging is not keeping up. I hope to restore it in the near future.

prometheus (2.4.3+ds-1) unstable; urgency=medium

  This release includes multiple bugfixes and features. Further, the WAL
  implementation has been re-written so the storage is not forwards compatible.
  Prometheus 2.3 storage will work on 2.4 but not vice-versa.

prometheus (2.2.0+ds-1) unstable; urgency=medium

  NOTE: This release introduces improvements to the storage format and fixes a
  regression introduced in 2.1. As a result Prometheus servers upgraded to 2.2
  cannot be downgraded to a lower version anymore!

prometheus (2.0.0+ds3-1) unstable; urgency=medium

  BREAKING CHANGES

  The data format in Prometheus 2.0 has completely changed and is not
  backwards compatible with 1.x. Prometheus 2 will create a new data directory
  in /var/lib/prometheus/metrics2. The old data in /var/lib/prometheus/metrics
  can not be read by the new version.

  There is no conversion tool; if you want to retain access to the old data,
  it is necessary to run a separate Prometheus 1.x instance on that data
  directory. (This package makes no provision to allow this.)


  Command-line flags now take two slashes. For example `-web.listen-address` is
  now `--web.listen-address`.


  Rules are now stored in YAML files instead of using a domain-specific
  language. The `promtool update rules` command can assist you in the
  transition.

prometheus (1.5.0+ds-1) unstable; urgency=medium

  Differences from upstream:

  * The profile support for EC2 discovery has been disabled, as that requires a
    different version of the AWS SDK.
  * Kubernetes support has been completely removed, due to the insane amount of
    dependencies in their client library.

prometheus (0.18.0+ds-1) unstable; urgency=medium

  * Support for the old alerting rule syntax was dropped for this version as
    announced with the 0.17.0 release.  The new alerting rule syntax is
    documented [1] and a script to convert existing rules exists [2]

    [1] http://prometheus.io/docs/alerting/rules/
    [2] https://gist.github.com/xbglowx/d798da98ff9937e33862b285d0121bde#gistcomment-1752515

  * This release introduces a new chunk encoding with variable bit width, in
    parts inspired by Facebook's "Gorilla" paper.  At the price of increased
    CPU cost and run-time of queries, the chunk space requirement drops by ~60%
    for typical data sets.  The varbit encoding has to be enabled with the
    command line flag -storage.local.chunk-encoding-version=2, all newly
    created chunks will have the new chunk encoding. It is safe to use a mix of
    different chunk encodings.

  * Several storage improvements dramatically increase the performance of
    instant queries for the most recent value of time series, as it typically
    happens in rule evaluations and for federation. On servers with a lot of
    series churn (i.e. many older series that don't receive samples anymore),
    we have seen a 12x speedup of rule evaluations with CPU usage reduced by
    75%.

prometheus (0.16.2+ds-1) unstable; urgency=high

  Breaking changes in this release:

  * Remove undocumented 2nd argument of the `delta` function.
  * Release tarballs now contain the built binaries in a nested directory.
  * The `hash_mod` relabeling action now uses MD5 hashes instead of FNV hashes
     to achieve a better distribution.
  * The DNS-SD meta label `__meta_dns_srv_name` was renamed to
     `__meta_dns_name` to reflect support for DNS record types other than
     `SRV`.
  * The default full refresh interval for the file-based service discovery has
     been increased from 30 seconds to 5 minutes.
  * In relabeling, parts of a source label that weren't matched by the
     specified regular expression are no longer included in the replacement
     output.
  * Queries no longer interpolate between two data points. 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). They have thus also been
     renamed from `global.labels` to `global.external_labels`.
  * 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.
  * Escape sequences in double- and single-quoted string literals in rules or
     query expressions are now interpreted like escape sequences in Go string
     literals (https://golang.org/ref/spec#String_literals).
