+# What's new in Grafana v7.2
+
+This topic includes the release notes for the Grafana v7.2, which is currently in beta. For all details, read the full [CHANGELOG.md](https://github.com/grafana/grafana/blob/master/CHANGELOG.md).
+
+This article is not complete yet. We will be adding new details over the coming days as we get closer to a stable
+release.
+
+The main highlights are:
+
+- [**Date formatting options**]({{< relref "#date-formatting-options" >}})
+- [**Table column filters**]({{< relref "#table-column-filters" >}})
+- [**New and improved transforms**]({{< relref "#new-and-improved-transforms" >}})
+- [**Field override matchers**]({{< relref "#field-override-matchers" >}})
+
+## Date formatting options
+
+Now you can finally customize how dates are formatted in Grafana. Both in the time range picker, graphs and other panels.
+
+Example:
+{{< docs-imagebox img="/img/docs/v72/date_formats.png" max-width="800px" caption="Custom date time formats" >}}
+
+The above screenshot shows both a custom full date format with a 12 hour clock and am/pm suffix. The Graph is also
+showing same 12 hour clock format and a customized month and day format compared to the Grafana default `MM/DD` format.
+
+Currently date formats can only be changed via [server wide settings]({{< relref
+"../administration/configuration.md#date_formats" >}}) but we hope to add org and potentially user level
+settings in the future.
+
+```
+[date_formats]
+full_date = MMM Do, YYYY @ hh:mm:ss a
+interval_second = hh:mm:ss a
+interval_minute = hh:mm a
+interval_hour = MMM DD hh:mm a
+interval_day = MMM DD
+interval_month = YYYY-MM
+interval_year = YYYY
+```
+
+There is also experimental support to use Browser locale/language to dynamically change the current date format
+for each user. This feature is disabled by default as it needs more testing and refinement.
+
+## Table column filters
+
+The new column filter option allow you to dynamically apply value filters to any column. This is option is disabled but
+can be enabled for all or a specific column using an override rule.
+
+{{< docs-imagebox img="/img/docs/v72/table_column_filters.png" max-width="800px" caption="Table column filters" >}}
+
+## New and improved transforms
+
+Grafana 7.2 includes a new group by transform that allows you to group by multiple fields and add any number of aggregations for other fields.
+
+There is also an update to the labels to fields transform that allow you to pick one label and use that as the name of the value field.
+
+The UI for transforms also has an update that now allows you to move transformations up and down.
+
+## Field override matchers
+
+You can now add override rules that use a regex matcher and overrides that match on field type.
+
+## Upgrading
+
+See [upgrade notes]({{< relref "../installation/upgrading.md" >}}).
+
+## Changelog
+
+Check out [CHANGELOG.md](https://github.com/grafana/grafana/blob/master/CHANGELOG.md) for a complete list of new features, changes, and bug fixes.
