## 2.43.0 / 2023-03-21
|
|
|
|
|
|
We are working on some performance improvements in Prometheus, which are only
|
|
|
built into Prometheus when compiling it using the Go tag `stringlabels`
|
|
|
(therefore they are not shipped in the default binaries). It uses a data
|
|
|
structure for labels that uses a single string to hold all the label/values,
|
|
|
resulting in a smaller heap size and some speedups in most cases. We would like
|
|
|
to encourage users who are interested in these improvements to help us measure
|
|
|
the gains on their production architecture. We are providing release artefacts
|
|
|
`2.43.0+stringlabels` and Docker images tagged `v2.43.0-stringlabels` with those
|
|
|
improvements for testing. #10991
|
|
|
|
|
|
* [FEATURE] Promtool: Add HTTP client configuration to query commands. #11487

|
|
|
* [FEATURE] HTTP client: Add `proxy_from_environment` to read proxies from env variables. #12098
|
|
|
* [ENHANCEMENT] API: Add support for setting lookback delta per query via the API. #12088
|
|
|
* [ENHANCEMENT] API: Change HTTP status code from 503/422 to 499 if a request is canceled. #11897

|
|
## 2.42.0 / 2023-01-31
|
|
|
|
|
|
This release comes with a bunch of feature coverage for native histograms and breaking changes.
|
|
|
|
|
|
If you are trying native histograms already, we recommend you remove the `wal` directory when upgrading.
|
|
|
Because the old WAL record for native histograms is not backward compatible in v2.42.0, this will lead to some data loss for the latest data.
|
|
|
|
|
|
Additionally, if you scrape "float histograms" or use recording rules on native histograms in v2.42.0 (which writes float histograms),
|
|
|
it is a one-way street since older versions do not support float histograms.
|
|
|
|
|

## 2.40.0 / 2022-11-08
|
|
|
|
|
|
This release introduces an experimental, native way of representing and storing histograms.
|
|
|
|
|
|
It can be enabled in Prometheus via `--enable-feature=native-histograms` to accept native histograms.
|
|
|
Enabling native histograms will also switch the preferred exposition format to protobuf.
|
|
|
|
|
|
To instrument your application with native histograms, use the `main` branch of `client_golang` (this will change for the final release when v1.14.0 of client_golang will be out), and set the `NativeHistogramBucketFactor` in your `HistogramOpts` (`1.1` is a good starting point).
|
|
|
Your existing histograms won't switch to native histograms until `NativeHistogramBucketFactor` is set.
|
|
|
|
|
|
* [FEATURE] Add **experimental** support for native histograms. Enable with the flag `--enable-feature=native-histograms`. #11447

## 2.35.0 / 2022-04-21
|
|
|
|
|
|
This Prometheus release is built with go1.18, which contains two noticeable changes related to TLS:
|
|
|
|
|
|
1. [TLS 1.0 and 1.1 disabled by default client-side](https://go.dev/doc/go1.18#tls10).
|
|
|
Prometheus users can override this with the `min_version` parameter of [tls_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#tls_config).
|
|
|
2. [Certificates signed with the SHA-1 hash function are rejected](https://go.dev/doc/go1.18#sha1). This doesn't apply to self-signed root certificates.
|
|
|
|
|
|
* [CHANGE] TSDB: Delete `*.tmp` WAL files when Prometheus starts. #10317
|
|
|
* [CHANGE] promtool: Add new flag `--lint` (enabled by default) for the commands `check rules` and `check config`, resulting in a new exit code (`3`) for linter errors. #10435
|
|
|
* [FEATURE] Support for automatically setting the variable `GOMAXPROCS` to the container CPU limit. Enable with the flag `--enable-feature=auto-gomaxprocs`. #10498
|
|
|
* [FEATURE] PromQL: Extend statistics with total and peak number of samples in a query. Additionally, per-step statistics are available with --enable-feature=promql-per-step-stats and using `stats=all` in the query API.
|
|
|
Enable with the flag `--enable-feature=per-step-stats`. #10369
|
|
|
* [ENHANCEMENT] Prometheus is built with Go 1.18. #10501
|

## 2.32.0 / 2021-12-09
|
|
|
|
|
|
This release introduces the Prometheus Agent, a new mode of operation for
|
|
|
Prometheus optimized for remote-write only scenarios. In this mode, Prometheus
|
|
|
does not generate blocks on the local filesystem and is not queryable locally.
|
|
|
Enable with `--enable-feature=agent`.
|
|
|
|
|

guaranteed to only see full scrapes and full recording rules. This comes with a
|
|
|
certain overhead in resource usage. Depending on the situation, there might be
|
|
|
some increase in memory usage, CPU usage, or query latency.

## 2.7.0 / 2019-01-28
|
|
|
|
|
|
We're rolling back the Dockerfile changes introduced in 2.6.0. If you made changes to your docker deployment in 2.6.0, you will need to roll them back. This release also adds experimental support for disk size based retention. To accommodate that we are deprecating the flag `storage.tsdb.retention` in favour of `storage.tsdb.retention.time`. We print a warning if the flag is in use, but it will function without breaking until Prometheus 3.0.

the user, it is still honored as usual.
|
|

## 0.16.0 / 2015-10-09
|
|
|
|
|
|
BREAKING CHANGES:
|
|
|
|
|
|
* 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>).
|
|
|
|
|
|
Future breaking changes / deprecated features:
|
|
|
|
|
|
* The `delta()` function had an undocumented optional second boolean argument
|
|
|
to make it behave like `increase()`. This second argument will be removed in
|
|
|
the future. Migrate any occurrences of `delta(x, 1)` to use `increase(x)`
|
|
|
instead.
|
|
|
* Support for filter operators between two scalar values (like `2 > 1`) will be
|
|
|
removed in the future. These will require a `bool` modifier on the operator,
|
|
|
e.g. `2 > bool 1`.
|
|
|
|
|
|
All changes:
|
|
|
|

|
|
BREAKING CHANGES:
|
|
|
|
|
|
* Relative paths for rule files are now evaluated relative to the config file.
|
|
|
* External reachability flags (`-web.*`) consolidated.
|
|
|
* The default storage directory has been changed from `/tmp/metrics`
|
|
|
to `data` in the local directory.
|
|
|
* The `rule_checker` tool has been replaced by `promtool` with
|
|
|
different flags and more functionality.
|
|
|
* Empty labels are now removed upon ingestion into the
|
|
|
storage. Matching empty labels is now equivalent to matching unset
|
|
|
labels (`mymetric{label=""}` now matches series that don't have
|
|
|
`label` set at all).
|
|
|
* The special `__meta_consul_tags` label in Consul service discovery
|
|
|
now starts and ends with tag separators to enable easier regex
|
|
|
matching.
|
|
|
* The default scrape interval has been changed back from 1 minute to
|
|
|
10 seconds.
|
|
|

## 0.12.0 / 2015-03-04
|
|
|
|
|
|
* [CHANGE] Use client_golang v0.3.1. THIS CHANGES FINGERPRINTING AND INVALIDATES
|
|
|
ALL PERSISTED FINGERPRINTS. You have to wipe your storage to use this or
|
|
|
later versions. There is a version guard in place that will prevent you to
|
|
|

|
|
|

|
|
|
|
|
|
## 0.11.1 / 2015-02-27
|
|
|
|
|
|
* [BUGFIX] Make series maintenance complete again. (Ever since 0.9.0rc4,
|
|
|
or commit 0851945, series would not be archived, chunk descriptors would
|
|
|
not be evicted, and stale head chunks would never be closed. This happened
|
|
|
due to accidental deletion of a line calling a (well tested :) function.
|
|
|
* [BUGFIX] Do not double count head chunks read from checkpoint on startup.
|
|
|
Also fix a related but less severe bug in counting chunk descriptors.
|
|
|
* [BUGFIX] Check last time in head chunk for head chunk timeout, not first.
|
|
|
* [CHANGE] Update vendoring due to vendoring changes in client_golang.
|
|
|
* [CLEANUP] Code cleanups.
|
|
|
* [ENHANCEMENT] Limit the number of 'dirty' series counted during checkpointing.
|
|
|
|
|
|

|
|
|
* [CHANGE] More efficient JSON result format in query API. This requires
|
|
|
up-to-date versions of PromDash and prometheus_cli, too.
|
|
|
* [ENHANCEMENT] Excluded non-minified Bootstrap assets and the Bootstrap maps
|
|
|
from embedding into the binary. Those files are only used for debugging,
|
|
|
and then you can use -web.use-local-assets. By including fewer files, the
|
|
|
RAM usage during compilation is much more manageable.
|
|
|
* [ENHANCEMENT] Help link points to <https://prometheus.github.io> now.
|
|
|
* [FEATURE] Consoles for haproxy and cloudwatch.
|
|

|
|
|
running very expensive queries accidentally.
|
|
|
* [CHANGE] On-disk format for stored samples changed. For upgrading, you have
|
|
|
to nuke your old files completely. See "Complete rewrite of the storage
|
