+# Release Notes for Superset 4.1.0
+
+Superset 4.1.0 brings a range of new features and quality of life
improvements. This release is a minor version, meaning it doesn't include any
breaking changes to ensure a seamless transition for our users. Here are some
of the highlights of this release.
+
+### Big Number With Time Period Updates
+
+We released a [Big Number with Time Period
Comparison](https://github.com/apache/superset/pull/26908) chart as part of
Superset 4.0. With the latest update, there are now [color
options](https://github.com/apache/superset/pull/27524) for comparisons. The
chart now also uses [standardize
controls](https://github.com/apache/superset/pull/27193) such that when
switching charts will maintain the selected metrics. To enable the new chart,
you'll need to enable the `CHART_PLUGINS_EXPERIMENTAL` [...]
+
+<div>
+ <image src="media/big_number_chart.png" alt="Image" width="100%">
+</div>
+
+### Table with Time Comparison
+Added functionality to do [table time
comparisons](https://github.com/apache/superset/pull/28057) behind the
`CHART_PLUGINS_EXPERIMENTAL` feature flag. This will help improve and
facilitate efficient data analysis.
+
+<div>
+ <image src="media/table_with_time.png" alt="Image" width="100%">
+</div>
+
+### New ECharts Versions
+
+The new ECharts [Heatmap](https://github.com/apache/superset/pull/25353) has
been added. Compared to the legacy Heatmap, it has more accurate percentage
calculations, server side sorting to respect row limits, and a more interactive
legend control that allows selecting a subset of values.
+
+<div>
+ <image src="media/heatmap.png" alt="Image" width="100%">
+</div>
+
+We also added a new ECharts
[Histogram](https://github.com/apache/superset/pull/28652) chart. The new chart
will help visualize patterns, clusters, and outliers in the data and provides
insights into its shape, central tendency, and spread.
+
+<div>
+ <image src="media/histogram.png" alt="Image" width="100%">
+</div>
+
+A new Echarts [Sankey](https://github.com/apache/superset/pull/29329) chart
now exists. The chart visually tracks the movement and transformation of values
across system stages.
+
+<div>
+ <image src="media/sankey.png" alt="Image" width="100%">
+</div>
+
+You can use the CLI command to migrate Area, Bubble, Line, Sankey,
[Heatmap](https://github.com/apache/superset/pull/27771), and
[Histogram](https://github.com/apache/superset/pull/28780) chart types but
we'll add more as the ECharts migrations continue. Note that migrations for
deprecated charts may be forced in upcoming major versions when the code is
removed. Running migrations earlier will allow you to de-risk future upgrades
while improving user experience.
+
+```bash
+Usage: superset viz-migrations [OPTIONS] COMMAND [ARGS]...
+
+ Migrates a viz from one type to another.
+
+Commands:
+ downgrade Downgrades a viz to the previous version.
+ upgrade Upgrade a viz to the latest version.
+```
+
+Note: When migrating dashboards from one Superset instance to another (using
import/export features or the Superset CLI), or restoring a backup of prior
charts and dashboards, Superset will apply the existing migrations that are
used during version upgrades. This will ensure that your charts and dashboards
are using the latest and greatest charts that Superset officially supports. For
any migration issues, feel free to [open a new
issue](https://github.com/apache/superset/issues/new?assi [...]
+
+### Improved Upload Forms
+
+We've made design changes to the
[CSV](https://github.com/apache/superset/pull/27840),
[Excel](https://github.com/apache/superset/pull/28105), and
[Columnar](https://github.com/apache/superset/pull/28192
+) upload modals to improve user experience and to be more performant. The new
designs has the following goals:
+
+- Improved error handling.
+- Better backend parameter validation.
+- More aligned with our other modal dialogs

+
+
+### OAuth2 For Databases
+
+You now have the ability to enable
[OAuth2](https://github.com/apache/superset/pull/27631) for databases like
BigQuery, Snowflake, Dremio, Databricks, Google Sheets, etc. When enabled, it
will allow users to connect to Oauth2 enabled databases with their own
credentials.
+
+### Catalog Support For Databases
+
+Added support for the [catalog
heirachy](https://github.com/apache/superset/pull/28317) for databases that
support it, such as [BigQuery (projects), Databricks, Presto, Snowflake, and
Trino](https://github.com/apache/superset/pull/28416). Once enabled, users will
see catalogs when selecting tables in [SQL Lab,
datasets](https://github.com/apache/superset/pull/28376), and when setting up
Data Access Roles
+
+### Slack Upload Files V2 API Updates
+As part of [[SIP-138] Proposal for Slack file upload V2 integration for Alerts
and Reports](https://github.com/apache/superset/issues/29263) we now have
support for Slack file upload files v2 API call. This feature is behind the
feature flag `ALERT_REPORT_SLACK_V2` and also changes the Slack channel to a
selector. You may also need to add the following scopes (`channels:read`,
`group:read`) to your Slack bot to work.
+
+<div>
+ <image src="media/slack_modal.png" alt="Image" width="100%">
+</div>
+
+### Total and Percentages In Tooltips For ECharts
+
+Users can now see both the [total and percentage in
tooltips](https://github.com/apache/superset/pull/27950) for ECharts.
+
+<div>
+ <image src="media/tooltips.png" alt="Image" width="100%">
+</div>
+
+### Additional Metadata Bar To Dashboards
+
+There is now a [metadata bar](https://github.com/apache/superset/pull/27857)
added to the header of dashboards. This will now show viewers of the dashboard
both the owners and last modified time of the dashboard.
