This enhancement clarifies potential drop points and helps avoid inadvertent placements in invalid areas. The update also aligns the drag-over feedback with the dashboard's drag-and-drop modifications, ensuring a uniform and enhanced user experience. + + + +### Dropping support for 3.0.X versions + +In accordance with our [release process](https://github.com/apache/superset/wiki/Release-Process), we are dropping support for the 3.0.X versions. As a result, we will no longer be providing bug fixes for these versions. We strongly recommend that all users upgrade to the latest version to take advantage of the newest features and bug fixes. Moving forward, the supported versions will be 3.1.X and 4.0.X. Bug fixes will continue to be backported to 3.1.X until the next minor release. For more information, please refer to our [release schedule](https://github.com/apache/superset/wiki/Release-Process#schedule). + +### Feature flag changes + +Following our 4.0 proposals, the following feature flags were removed: + +- `VERSIONED_EXPORT` +- `DASHBOARD_FILTERS_EXPERIMENTAL` +- `ENABLE_EXPLORE_JSON_CSRF_PROTECTION` +- `ENABLE_TEMPLATE_REMOVE_FILTERS` +- `REMOVE_SLICE_LEVEL_LABEL_COLORS` +- `CLIENT_CACHE` +- `DASHBOARD_CACHE` +- `DASHBOARD_NATIVE_FILTERS_SET` +- `ENABLE_EXPLORE_DRAG_AND_DROP` +- `DISABLE_DATASET_SOURCE_EDIT` +- `DASHBOARD_NATIVE_FILTERS` +- `GENERIC_CHART_AXES` + +The following feature flags were deprecated: + +- `DASHBOARD_CROSS_FILTERS` +- `ENABLE_JAVASCRIPT_CONTROLS` +- `KV_STORE` + +The following feature flags were enabled by default: + +- `DASHBOARD_VIRTUALIZATION` +- `DRILL_BY` + +### Removed features + +As part of the 4.0 approved initiatives, the following features were removed from Superset: + +- Filter Box: [#26328](https://github.com/apache/superset/pull/26328) removed the Filter Box code and it's associated dependencies `react-select` and `array-move`. It also removed the `DeprecatedSelect` and `AsyncSelect` components that were exclusively used by filter boxes. Existing filter boxes will be automatically migrated to native dashboard filters. + +- Filter Sets: [#26369](https://github.com/apache/superset/pull/26369) removed the Filters Set feature including the deprecated `DASHBOARD_NATIVE_FILTERS_SET` feature flag and all related API endpoints. The feature is permanently removed as it was not being actively maintained, it was not widely used, and it was full of bugs. We also considered that if we were to provide a similar feature, it would be better to re-implement it from scratch given the amount of technical debt that the implementation had. + +- Profile: [#26462](https://github.com/apache/superset/pull/26462) removed the Profile feature given that it was not actively maintained nor widely used. + +- Redirect API: [#26377](https://github.com/apache/superset/pull/26377) removed the deprecated Redirect API that supported short URLs (`/r`) and the `url` metadata table used to store them that was used before the permalink feature. Users lost the ability to generate R links ~1.5 years ago which seems sufficient time to remove the API. + +### Business logic improvements + +As part of [[SIP-99] Proposal for correctly handling business logic](https://github.com/apache/superset/issues/25048) (specifically [SIP-99A](https://github.com/apache/superset/issues/25107) and [SIP-99B](https://github.com/apache/superset/issues/25108)), this release contains many improvements to the handling of business logic in Superset, specifically related to SQLAlchemy sessions and transactions. The goal of these efforts is to simplify the code, improve code quality, ensure a consistent "unit of work" approach, and provide clear guidance and examples of accepted code standards. These changes aim to improve developer experience by making the code simpler, improving testing, and ensuring a more streamlined and reliable system. We still have a long way to go to fully implement the SIP-99 proposal, but we are making progress and we are excited about the improvements that have been made so far. + +### All country maps are now managed via Jupyter Notebook + +In this release we made updates to the Jupyter Notebook to ensure reliable execution by removing deprecated methods, adding new countries, including missing maps and fixing filename inconsistencies. This will make it easier to add more countries, dynamically add them to the country map plugin, and update map regions periodically. You can check [#26300](https://github.com/apache/superset/pull/26300) for more details. + +### Sunburst chart migrated to ECharts + +The ECharts version of the Sunburst chart was introduced by [#22833](https://github.com/apache/superset/pull/22833) as part of our efforts to complete [SIP-50](https://github.com/apache/superset/issues/10418). In 4.0, legacy Sunburst charts are [automatically migrated](https://github.com/apache/superset/pull/26350) to ECharts and the legacy version was removed. + + + +### Some cool stats + +- ~15K lines of code were removed by PRs related to 4.0 proposals +- We reduced the number of NPM packages vulnerabilities by 72% + - 3.1: 90 vulnerabilities (42 moderate, 34 high, 14 critical) + - 4.0: 25 vulnerabilities (16 moderate, 8 high, 1 critical) +- 40+ dependency changes (upgrades, additions, and removals) + +### How to upgrade + +As with any Superset version upgrade, the process is simple in the broadest strokes, as outlined in the documentation. However, as with any upgrade, we expect to see numerous speed bumps along that path depending on your configuration, your infrastructure, your databases in use, and other customizations/configurations. To make a safe leap to this version, we'd suggest the following steps: + +- Back up your databases +- Carefully read `CHANGELOG.md` for all the incremental changes in this version (and prior versions, between your current installation and 4.0.0). +- Similarly, review `UPDATING.md` to keep an eye out for all changes that have been explicitly marked as breaking changes. +- Adjust your feature flags and configurations to meet your feature requirements and preferences. +- Execute the migrations +- If you have third-party apps interacting with Superset, check for relevant dependency updates or API endpoint changes that may affect compatibility. + +Your mileage may vary depending on: + +- How you install and deploy Superset (e.g. docker vs. pip vs. helm) +- How you’ve configured Superset +- What integrations, databases, etc. you’re using Review Comment: ```suggestion - What integrations, databases, etc. you're using ``` ########## RELEASING/release-notes-4-0/README.md: ########## @@ -0,0 +1,151 @@ +<!-- +Licensed to the Apache Software Foundation (ASF) under one +or more contributor license agreements.

This might clarify that. Perhaps we should even remove "filters" from the modal. ########## RELEASING/release-notes-4-0/README.md: ########## @@ -0,0 +1,151 @@ +<!-- +Licensed to the Apache Software Foundation (ASF) under one +or more contributor license agreements.

It also removed the `DeprecatedSelect` and `AsyncSelect` components that were exclusively used by filter boxes. Existing filter boxes will be automatically migrated to native dashboard filters. + +- Filter Sets: [#26369](https://github.com/apache/superset/pull/26369) removed the Filters Set feature including the deprecated `DASHBOARD_NATIVE_FILTERS_SET` feature flag and all related API endpoints. The feature is permanently removed as it was not being actively maintained, it was not widely used, and it was full of bugs. We also considered that if we were to provide a similar feature, it would be better to re-implement it from scratch given the amount of technical debt that the implementation had. + +- Profile: [#26462](https://github.com/apache/superset/pull/26462) removed the Profile feature given that it was not actively maintained nor widely used. + +- Redirect API: [#26377](https://github.com/apache/superset/pull/26377) removed the deprecated Redirect API that supported short URLs (`/r`) and the `url` metadata table used to store them that was used before the permalink feature. Users lost the ability to generate R links ~1.5 years ago which seems sufficient time to remove the API. + +### Business logic improvements + +As part of [[SIP-99] Proposal for correctly handling business logic](https://github.com/apache/superset/issues/25048) (specifically [SIP-99A](https://github.com/apache/superset/issues/25107) and [SIP-99B](https://github.com/apache/superset/issues/25108)), this release contains many improvements to the handling of business logic in Superset, specifically related to SQLAlchemy sessions and transactions. The goal of these efforts is to simplify the code, improve code quality, ensure a consistent "unit of work" approach, and provide clear guidance and examples of accepted code standards. These changes aim to improve developer experience by making the code simpler, improving testing, and ensuring a more streamlined and reliable system. We still have a long way to go to fully implement the SIP-99 proposal, but we are making progress and we are excited about the improvements that have been made so far. + +### All country maps are now managed via Jupyter Notebook + +In this release we made updates to the Jupyter Notebook to ensure reliable execution by removing deprecated methods, adding new countries, including missing maps and fixing filename inconsistencies. This will make it easier to add more countries, dynamically add them to the country map plugin, and update map regions periodically. You can check [#26300](https://github.com/apache/superset/pull/26300) for more details. + +### Sunburst chart migrated to ECharts + +The ECharts version of the Sunburst chart was introduced by [#22833](https://github.com/apache/superset/pull/22833) as part of our efforts to complete [SIP-50](https://github.com/apache/superset/issues/10418). In 4.0, legacy Sunburst charts are [automatically migrated](https://github.com/apache/superset/pull/26350) to ECharts and the legacy version was removed. + + + +### Some cool stats + +- ~15K lines of code were removed by PRs related to 4.0 proposals +- We reduced the number of NPM packages vulnerabilities by 72% + - 3.1: 90 vulnerabilities (42 moderate, 34 high, 14 critical) + - 4.0: 25 vulnerabilities (16 moderate, 8 high, 1 critical) +- 40+ dependency changes (upgrades, additions, and removals) + +### How to upgrade + +As with any Superset version upgrade, the process is simple in the broadest strokes, as outlined in the documentation. However, as with any upgrade, we expect to see numerous speed bumps along that path depending on your configuration, your infrastructure, your databases in use, and other customizations/configurations. To make a safe leap to this version, we'd suggest the following steps: + +- Back up your databases +- Carefully read `CHANGELOG.md` for all the incremental changes in this version (and prior versions, between your current installation and 4.0.0). Review Comment: ```suggestion - Carefully read `CHANGELOG.md` for all the incremental changes in this version (and any prior versions between your current installation and 4.0.0). ``` ########## RELEASING/release-notes-4-0/README.md: ########## @@ -0,0 +1,151 @@ +<!-- +Licensed to the Apache Software Foundation (ASF) under one +or more contributor license agreements.
