## unreleased
* [FEATURE] OTLP receiver: Add new option `otlp.promote_resource_attributes`, for any OTel resource attributes that should be promoted to metric labels. #14200
* [FEATURE] Remote-Write: Add sender and receiver support for [Remote Write 2.0-rc.2](https://prometheus.io/docs/specs/remote_write_spec_2_0/) specification #14395 #14427 #14444
* [ENHANCEMENT] Remote-Write: 1.x messages against Remote Write 2.x Receivers will have now correct values for `prometheus_storage_<samples|histograms|exemplar>_failed_total` in case of partial errors #14444
## 2.53.1 / 2024-07-10
Fix a bug which would drop samples in remote-write if the sending flow stalled

Prometheus provides a functional query language called PromQL (Prometheus Query
Language) that lets the user select and aggregate time series data in real
time. The result of an expression can either be shown as a graph, viewed as
tabular data in Prometheus's expression browser, or consumed by external
systems via the [HTTP API](api.md).
time.
When you send a query request to Prometheus, it can be an _instant query_, evaluated at one point in time,
or a _range query_ at equally-spaced steps between a start and an end time. PromQL works exactly the same
in each cases; the range query is just like an instant query run multiple times at different timestamps.
In the Prometheus UI, the "Table" tab is for instant queries and the "Graph" tab is for range queries.
Other programs can fetch the result of a PromQL expression via the [HTTP API](api.md).

## Time series selectors
Time series selectors are responsible for selecting the times series and raw or inferred sample timestamps and values.
Time series *selectors* are not to be confused with higher level concept of instant and range *queries* that can execute the time series *selectors*. A higher level instant query would evaluate the given selector at one point in time, however the range query would evaluate the selector at multiple different times in between a minimum and maximum timestamp at regular steps.
These are the basic building-blocks that instruct PromQL what data to fetch.
### Instant vector selectors

//
// Let's say the old buckets look like this:
//
// span syntax: [offset, length]
// spans : [ 0 , 2 ] [2,1] [ 3 , 2 ] [3,1] [1,1]
// bucket idx : [0] [1] 2 3 [4] 5 6 7 [8] [9] 10 11 12 [13] 14 [15]
// raw values 6 3 3 2 4 5 1
// deltas 6 -3 0 -1 2 1 -4
//
// But now we introduce a new bucket layout. (Carefully chosen example where we
// have a span appended, one unchanged[*], one prepended, and two merge - in
// that order.)
//
// [*] unchanged in terms of which bucket indices they represent. but to achieve
// that, their offset needs to change if "disrupted" by spans changing ahead of
// them
//
// \/ this one is "unchanged"
// spans : [ 0 , 3 ] [1,1] [ 1 , 4 ] [ 3 , 3 ]
// bucket idx : [0] [1] [2] 3 [4] 5 [6] [7] [8] [9] 10 11 12 [13] [14] [15]
// raw values 6 3 0 3 0 0 2 4 5 0 1
// deltas 6 -3 -3 3 -3 0 2 2 1 -5 1
// delta mods: / \ / \ / \
//
// Note for histograms with delta-encoded buckets: Whenever any new buckets are
// introduced, the subsequent "old" bucket needs to readjust its delta to the
// new base of 0. Thus, for the caller who wants to transform the set of
// original deltas to a new set of deltas to match a new span layout that adds
// buckets, we simply need to generate a list of inserts.
