# Release Notes

## August 25th, 2025 (v1.4.1)

**Module tiler**

New

* Added option `max_categories_limit` that controls the maximum number of categories from string columns included in metadata for every tiler procedure.

## September 24th, 2024 (v1.4.0)

**Module tiler**

New

* Add `tile_resolution` to all [tileset](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/tiler.md) creation options. This new setting allows controlling the size of the tiles when rendered in a map. Higher values produce larger tiles.

Fix

* Support empty properties in [CREATE\_POINT\_AGGREGATION\_TILESET](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/tiler.md#create_point_aggregation_tileset) procedures.
* Fix [CREATE\_SIMPLE\_TILESET](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/tiler.md#create_simple_tileset) procedure in order to support any geom column name.

## January 18th, 2024 (v1.3.0)

**Module quadbin**

New

* New [QUADBIN\_DISTANCE](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/quadbin.md#quadbin_distance) function that returns the distance (number of cells) between two quadbin cells.

Fix

* Improved precision when calculating cell indexes from latitudes close to the poles (±90º).

**Module tiler**

Fix

* Fixed a problem when parsing quotes inside the input query in [CREATE\_SIMPLE\_TILESET](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/tiler.md#create_simple_tileset) and [CREATE\_POINT\_AGGREGATION\_TILESET](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/tiler.md#create_point_aggregation_tileset) procedures.
* Improved bounds calculation to get the exact value when using h3 cells in the [CREATE\_SPATIAL\_INDEX\_TILESET](/data-and-analysis/analytics-toolbox-for-postgresql/sql-reference/tiler.md#create_spatial_index_tileset) procedure. This applies when the Analytics Toolbox is installed with the h3 module ([depends on having `plv8` extenstion installed](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-postgresql/getting-access#installing-extensions)).

## December 23, 2023 (v1.2.2)
