We've got this written up in the Writer's Toolkit, but it's not very clear.
I believe the format you want to use in this case is:

[link text](/products/cloud/k6)

Because the product page is outside of the Loki repository, but still part of the Grafana website.

    Label Volume Endpoint (#9588)

    For a given set of matchers, returns the top N associated label/value
    pairs by volume. A query for `{cluster=prod}` will return

    ```
    cluster=prod: size (total logs matching this matcher)
     .
     .
     .
    nth-label=nth-value
    ```

    This is to service use cases where users want to understand where their
    log volume has come from by label without making multiple requests to
    the stats endpoint.

    Note: This PR is a monster but it's mostly plumbing. I've pointed out
    the most interesting bits that actually get the volumes from
    ingesters/indexs

    Fix promtail cluster template not finding all clusters. (#9684)

    **What this PR does / why we need it**:
    In promtail-mixin, the dropdown template for clusters would only include
    clusters that run loki. So if a cluster only run promtail and not loki,
    it doesn't appear.

    feat(lambda-promtail): add cloudfront log file ingestion support (#9573)

    **What this PR does / why we need it**:

    This PR enables ingesting logs from Cloudfront log files stored in s3
    (batch).
    The current setup only supports streaming Cloudfront logs through AWS
    Kinesis, whereas this PR implements the same flow as for VPC Flow logs,
    Load Balancer logs, and Cloudtrail logs (s3 --> SQS (optional) -->
    Lambda Promtail --> Loki)

    **Special notes for your reviewer**:
    + The Cloudfront log file format is different from the already
    implemented services, meaning we had to build yet another regex. AWS
    never bothered making all services follow the same log file naming
    convention but the "good" thing is that it's now very unlikely they will
    change it in the future.
    + The Cloudfront file name does not have any mention of the AWS account
    or the time of log it contains, it means we have to infer the log type
    from the filename format instead of finding the exact string
    "cloudfront" in the filename. This is why in `getLabels`, if no `type`
    parameter is found in the regex, we use the key corresponding to the
    name of the matching parser.
    + I introduced a new `parser` struct to group together several
    parameters specific to a type of log (and avoid relying too much on map
    key string matching and / or if statements for specific use cases)
    + I've been successfully running this code in several AWS environments
    for days.
    + I corrected a typo from my previous PR #9497 (wrong PR number in
    Changelog.md)

    Add config to avoid caching stats for recent data (#9537)

    **What this PR does / why we need it**:

    When we query the stats for recent data, we query both the ingesters and
    the index gateways for the stats.

    https://github.com/grafana/loki/blob/ebdb2b18007e024d56105afc5230383165ca1650/pkg/storage/async_store.go#L112-L114

    https://github.com/grafana/loki/blob/ebdb2b18007e024d56105afc5230383165ca1650/pkg/storage/async_store.go#L126-L127

    Then we merge all the responses, which means summing up all the stats

    https://github.com/grafana/loki/blob/ebdb2b18007e024d56105afc5230383165ca1650/pkg/storage/async_store.go#L157-L158

    https://github.com/grafana/loki/blob/ebdb2b18007e024d56105afc5230383165ca1650/pkg/storage/stores/index/stats/stats.go#L23-L26

    Because we have a replication factor of 3, this means that we will get
    the stats from the ingesters repeated up to 3 times, hence inflating the
    stats.

    In the stats cache, we store the stats for a given matcher set for the
    whole day, then we extract the stats from the cache by the factor of
    time from the request that is stored in the cache:

    https://github.com/grafana/loki/blob/336283acadb34f5fda9abce4e6fcef1dca9965d8/pkg/querier/queryrange/index_stats_cache.go#L33

    https://github.com/grafana/loki/blob/336283acadb34f5fda9abce4e6fcef1dca9965d8/pkg/querier/queryrange/index_stats_cache.go#L40

    Inflated stats for recent data will be cached, so subsequent stats
    extracted from the cache will be inflated regardless of the time.

    This PR adds a new per-tenant limit `max_stats_cache_freshness` to not
    cache requests with an end time that falls within Now minus this
    duration.

    Here's a scenario illustrating this. The graphs below show the bytes
    stats queried in the sharding middleware. We are running a log filter
    query that won't match any log, every 5 seconds with a length of 3h.

    ![image](https://github.com/grafana/loki/assets/8354290/45c2e6e9-185c-4a18-b290-47da27fc3e39)

    As can be seen, after enabling the stats cache and
    configuring`do_not_cache_request_within` to not cache stats for requests
    within 30m, the bytes stats used in the sharding middleware stopped
    increasing.

    In both cases the stats cache hit ration was 100%.

    ![image](https://github.com/grafana/loki/assets/8354290/cd35bcb8-0c77-4693-a06b-502741fd6e23)

    **Special notes for your reviewer**:
    - Blocked by #9535
    - Note that this PR doesn't fix the root issue of inflated stats form
    the ingesters, but rather buys us some time to work on that.

    feat(promtail): add CF ClientRequestSource field (#9669)

    **What this PR does / why we need it**:

    Hey folks 👋

    Little contribution here to add a useful log field for cloudflare users.
    Indeed I add the [ClientRequestSource
    field](https://developers.cloudflare.com/logs/reference/clientrequestsource/
    ) which is pretty useful when debugging some specific traffic handled by
    cloudflare

    Extra: Since I was on the documentation I fixed an indentation issue
    that I spotted

    Don't hesitate to reach me if you have any questions

    Cheers 😉

    config: ensure storage config defaults apply to named stores (#9650)

    **What this PR does / why we need it**:
    Since named store config does not register any flags, storage configs
    defined under it do not get the defaults.
    For example
    [aws_storage_config](https://grafana.com/docs/loki/latest/configuration/#aws_storage_config)
    sets the default `storage_class` to `STANDARD`, but the same doesn't get
    applied by default when using named stores.

    This PR ensures that named storage configs are always assigned default
    values when they are unmarshalled by implementing `yaml.Unmarshaler`
    interface

    Adding background cache (en|de)queue counters (#9665)

    **What this PR does / why we need it**:
    The background writeback cache exposes gauge metric currently for the
    current queue size. Gauges can be useful, but they are susceptible to
    sample errors because they only represent the point in time as the time
    of the scrape.

    Exposing counters for the bytes (en|de)queued to/from the cache will be
    more useful because they can be aggregated.

    https://github.com/grafana/loki/blob/ebdb2b18007e024d56105afc5230383165ca1650/pkg/storage/async_store.go#L157-L158

    https://github.com/grafana/loki/blob/ebdb2b18007e024d56105afc5230383165ca1650/pkg/storage/stores/index/stats/stats.go#L23-L26

    Because we have a replication factor of 3, this means that we will get
    the stats from the ingesters repeated up to 3 times, hence inflating the
    stats.

    In the stats cache, we store the stats for a given matcher set for the
    whole day, then we extract the stats from the cache by the factor of
    time from the request that is stored in the cache:

    https://github.com/grafana/loki/blob/336283acadb34f5fda9abce4e6fcef1dca9965d8/pkg/querier/queryrange/index_stats_cache.go#L33

    https://github.com/grafana/loki/blob/336283acadb34f5fda9abce4e6fcef1dca9965d8/pkg/querier/queryrange/index_stats_cache.go#L40

    Inflated stats for recent data will be cached, so subsequent stats
    extracted from the cache will be inflated regardless of the time.

    This PR adds a new per-tenant limit `max_stats_cache_freshness` to not
    cache requests with an end time that falls within Now minus this
    duration.

    Here's a scenario illustrating this. The graphs below show the bytes
    stats queried in the sharding middleware. We are running a log filter
    query that won't match any log, every 5 seconds with a length of 3h.

    As can be seen, after enabling the stats cache and
    configuring`do_not_cache_request_within` to not cache stats for requests
    within 30m, the bytes stats used in the sharding middleware stopped
    increasing.

    In both cases the stats cache hit ration was 100%.

    **Special notes for your reviewer**:
    - Blocked by #9535
    - Note that this PR doesn't fix the root issue of inflated stats form
    the ingesters, but rather buys us some time to work on that.

    Fix date template function with epoch times (#8886)

    **What this PR does / why we need it**:

    Adds new toUnixEpoch... functions to convert from a string with a
    Unix/Epoch time to an integer that can be used in the existing `toDate`
    function.

    Note that these are the opposites of some of the functions introduced in
    #8774.

    **Which issue(s) this PR fixes**:
    Fixes #8624.

    feat(promtail): add CF ClientRequestSource field (#9669)

    **What this PR does / why we need it**:

    Hey folks 👋

    Little contribution here to add a useful log field for cloudflare users.
    Indeed I add the [ClientRequestSource
    field](https://developers.cloudflare.com/logs/reference/clientrequestsource/
    ) which is pretty useful when debugging some specific traffic handled by
    cloudflare

    Extra: Since I was on the documentation I fixed an indentation issue
    that I spotted

    Don't hesitate to reach me if you have any questions

    Cheers 😉

    config: ensure storage config defaults apply to named stores (#9650)

    **What this PR does / why we need it**:
    Since named store config does not register any flags, storage configs
    defined under it do not get the defaults.
    For example
    [aws_storage_config](https://grafana.com/docs/loki/latest/configuration/#aws_storage_config)
    sets the default `storage_class` to `STANDARD`, but the same doesn't get
    applied by default when using named stores.

    This PR ensures that named storage configs are always assigned default
    values when they are unmarshalled by implementing `yaml.Unmarshaler`
    interface

    Adding background cache (en|de)queue counters (#9665)

    **What this PR does / why we need it**:
    The background writeback cache exposes gauge metric currently for the
    current queue size. Gauges can be useful, but they are susceptible to
    sample errors because they only represent the point in time as the time
    of the scrape.

    Exposing counters for the bytes (en|de)queued to/from the cache will be
    more useful because they can be aggregated.

    Make table manager retention options configurable in helm chart values (#9647)

    **What this PR does / why we need it**:

    Configuration options for table manager retention are hard-coded in the
    helm chart values at the moment so that it's not possible to enable
    retention deletes.
