# Release Notes

## March 27th, 2026 (v1.13.0)

**Architecture**

Fix

* Improved package installer to properly handle function drops and support port and SSL configuration options.

**Module lds**

Fix

* Updated [CREATE\_H3\_ISOLINES](https://docs.carto.com/data-and-analysis/sql-reference/lds#create_h3_isolines) procedure to fix edge cases that didn't allow preview in workflows.
* Migrated [CREATE\_H3\_ISOLINES](https://docs.carto.com/data-and-analysis/sql-reference/lds#create_h3_isolines) implementation to not use Python UDFs, in line with the ongoing deprecation.

The[ installation process](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-redshift/getting-access) has been updated accordingly to also install these lambda functions.

**Module lds**

New

* Add [H3\_ISOLINE](https://docs.carto.com/data-and-analysis/sql-reference/lds#h3_isoline) function and [CREATE\_H3\_ISOLINES](https://docs.carto.com/data-and-analysis/sql-reference/lds#create_h3_isolines) procedure in order to calculate H3 isochrones from a given point by using [Traveltime](https://docs.traveltime.com/api/reference/h3) services.

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

**Module lds**

Fix

* Improved handling of FQNs in [CREATE\_ISOLINES](https://docs.carto.com/data-and-analysis/sql-reference/lds#create_isolines) and [CREATE\_ROUTES](https://docs.carto.com/data-and-analysis/sql-reference/lds#create_routes) procedures..

## July 2nd, 2024 (v1.7.1)

**Module import**

New

* We have a new module named “import”. It allows importing tables for a given URL containing a file in any of the formats supported by the CARTO Import API. The procedure in charge of this import is [`IMPORT_URL`](https://docs.carto.com/data-and-analysis/sql-reference/import#import_url).

## April 18th, 2024 (v1.6.1)

**Module clustering**

Fix

* Update [`ST_CLUSTERKMEANS`](https://docs.carto.com/data-and-analysis/sql-reference/clustering#st_clusterkmeans) in order to avoid generating less clusters than requested. The maximum number of clusters now will be equal to the number of different points passed.

**Module lds**

Fix

## March 21st, 2024 (v1.6.0)

**Module lds**

New

* All external functions (including those used by the procedures in the lds module) now use a single, unified endpoint. This also simplifies the manual installation of the Analytics Toolbox.
* [GEOCODE\_TABLE](https://docs.carto.com/data-and-analysis/sql-reference/lds#geocode_table) now uses async batch geocoding with TomTom, boosting the geocoding speed considerably. Also matching by rows is applied ensuring that the address that reaches the TomTom endpoints is as similar as possible as the table value.

## February 16th, 2024 (v1.5.1)

**Module lds**

Fix

* [CREATE\_ISOLINES](https://docs.carto.com/data-and-analysis/sql-reference/lds#create_isolines) fixed a problem with using input credentials for all requests.

* Fixed a problem with the output of [ST\_MAKEENVELOPE](https://docs.carto.com/data-and-analysis/sql-reference/constructors#st_makeenvelope) function, it now returns a GEOMETRY with SRID 4326.

**Module transformations**

Fix

* Fixed a problem with the output of [ST\_CENTERMEAN](https://docs.carto.com/data-and-analysis/sql-reference/transformations#st_centermean), [ST\_CENTERMEDIAN](https://docs.carto.com/data-and-analysis/sql-reference/transformations#st_centermedian), [ST\_CENTROID](https://docs.carto.com/data-and-analysis/sql-reference/transformations#st_centroid), [ST\_DESTINATION](https://docs.carto.com/data-and-analysis/sql-reference/transformations#st_destination) and [ST\_GREATCIRCLE](https://docs.carto.com/data-and-analysis/sql-reference/transformations#st_greatcircle) functions, they now return a GEOMETRY with SRID 4326.

**Module tiler**

Fix

* Fixed a problem with [CREATE\_SIMPLE\_TILESET](https://docs.carto.com/data-and-analysis/sql-reference/tiler#create_simple_tileset) procedure, that was crashing when the value for the “max\_tile\_size\_strategy” property was "drop\_fraction\_as\_needed" in points tables.
* Improved tile precision when creating tilesets from geometries containing points with latitudes close to the poles (±90º) using [CREATE\_SIMPLE\_TILESET](https://docs.carto.com/data-and-analysis/sql-reference/tiler#create_simple_tileset) or [CREATE\_POINT\_AGGREGATION\_TILESET](https://docs.carto.com/data-and-analysis/sql-reference/tiler#create_point_aggregation_tileset).
* Improved bounds calculation to get an approximate value when using h3 cells in the [CREATE\_SPATIAL\_INDEX\_TILESET](https://docs.carto.com/data-and-analysis/sql-reference/tiler#create_spatial_index_tileset) procedure.

**Module data**

Fix

New

* We are now allowing users to send any of the parameter options supported by the isolines service provider in [CREATE\_ISOLINES](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-bigquery/sql-reference/lds#create_isolines).
* We have improved our logging of results in [GEOCODE\_TABLE](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-redshift/sql-reference/lds#geocode_table) so more information about processed and geocoded rows is provided to the user. Also the new option “carto\_force\_geocode” allows the re-geocoding of already geocoded rows.

Fix

* We have applied some fixes to the [CREATE\_ROUTES](https://docs.carto.com/data-and-analysis/analytics-toolbox-for-redshift/sql-reference/lds#create_routes) function so the metadata column can be successfully created and informed.
