## v4.1

**Q4 2022**

### Data coverage improvements

This minor release includes an update to the U.S. legislative datasets and U.S. territories based on the decennial [redistricting data program](https://www.census.gov/programs-surveys/decennial-census/about/rdo.html) from the 2020 Census.

## v4.0

**Q3 2022**

This major release includes several breaking API and data changes. See [Migrate from v3 to v4](https://docs.mapbox.com/data/boundaries/guides/boundaries-v4-migration-guide/) for details on migrating your application.

### Breaking changes

-   The primary key field in the vector tilesets and lookup tables is now a globally unique [`mapbox_id`](https://docs.mapbox.com/data/boundaries/reference/mapbox-boundaries-v4#mapbox_id-text). The primary key values of `feature_id` and `id` are now deprecated and will no longer work for joins with v4 tilesets. References to all v3 IDs need to be recomputed and all Boundaries tilesets must be added to a Mapbox map using a `promoteId: "mapbox_id"` argument.
-   Boundaries lookup tables are only delivered in flat CSV format. Nested JSON lookup tables have been deprecated.
-   Several fields in the [Boundaries lookup tables](https://docs.mapbox.com/data/boundaries/reference/mapbox-boundaries-v4#csv-fields) have been renamed for consistency.
-   Data reorganization and fixes to many layers have resulted in breaking changes in data coverage:
-   US-legislative layers have been temporarily removed to make way for final 2022 redistricting boundaries in v4.1.
-   US-locality layers have been completely reorganized for parity with [Mapbox Search API](https://docs.mapbox.com/api/search/).
-   See the [migration guide](https://docs.mapbox.com/data/boundaries/guides/boundaries-v4-migration-guide#breaking-api-changes) for a full list of breaking data layers.

## v3.0

**Q1 2020**

[Release blog post](https://medium.com/mapbox/using-boundaries-for-election-analysis-5b0d15001e03)

### Data types and tilesets

-   Two new data types, `locality` and `legislative`, will be included as part of the product to complement the existing data types of `administrative`, `postal`, and `statistical`.
-   The `locality` data type will have 4 levels that aim to capture local expectations of settlements that have non-official or fuzzy areas: Level 1 = Metro */} Level 2 = City */} Level 3 = District */} Level 4 = Neighborhood.
-   The `legislative` data type will have 5 levels that capture electoral boundaries: Level 1 = National Upper (aka US Senate) */} Level 2 = National Lower (aka US House of Representatives) */} Level 3 = Regional Upper (State Senate) */} Level 4 = Regional Lower (State House) */} Level 5 = Local (Community or Town specific boundaries).
-   Separated lines and points tilesets that enable the inclusion of names on a map from the points tilesets.

### Worldviews / Disputes

-   New [Japanese worldview](https://demos.mapbox.com/boundaries-explorer/?country=JP&layer=adm1&worldview=JP#5/34.78/134.38).

### Data coverage improvements

-   US scope expanded to include `cities` and municipalities. The definition of a city is fluid in how it's used and perceived by people. To avoid misrepresenting a boundary, we used several data types and levels to properly capture US city and municipality boundary polygons.
-   `Admin`, [level 3](https://demos.mapbox.com/boundaries-explorer/?country=US&layer=adm3&worldview=US#6.19/41.002/-74.904) = US county sub-divisions that are active governments or entities with designated officials that provide primary general-purpose functions to their residents.
-   `Admin`, [level 4](https://demos.mapbox.com/boundaries-explorer/?country=US&layer=adm4&worldview=US#6.19/41.002/-74.904) = US census incorporated places (excludes Census Designated Places, or CDPs, which are only statistical).
-   `Stats`, [level 3](https://demos.mapbox.com/boundaries-explorer/?country=US&layer=sta3&worldview=US#6.19/41.002/-74.904) = all US county sub-divisions (all serve a statistical purpose, while only some serve an administrative purpose).
-   `Locality`, [level 2](https://demos.mapbox.com/boundaries-explorer/?country=US&layer=loc2&worldview=US#6.19/41.002/-74.904) = this level was created to provide a one-stop location to provide what people colloquially refer to as a city in the US. It is constructed by using all US county sub-divisions as a basis, then adding all US census places (both incorporated and CDPs).
-   Completed a full review of all global Administrative boundaries, which resulted in recategorizing several boundaries to a statistical or legislative level as the purpose, function, or both purpose and function of those boundaries was changed by the government.
