* Existing Hyper files will continue to work, however, SQL queries will need to be adjusted
* For example, instead of `geo_make_point` you must now use `tableau.geo_make_point` in SQL queries
* The plain `geography` type and all geospatial functions outside the `tableau` namespace are deprecated and will be removed in the near future
* See [Geographic Functions](/docs/sql/scalar_func/geography) and [Add Spatial Data to a Hyper File](/docs/guides/hyper_file/geodata) for more information

* IANA released version 2024a of the Time Zone Database. Hyper’s time zone information is updated accordingly. Noteworthy changes:
* Paraguay adopts permanent -03 starting spring 2024
* Improve historical data for Mexico, Mongolia, Philippines, and Portugal

* Hyper now adjusts the resulting interval from a timestamp subtraction so that 24-hour time periods are represented as days.
* Hyper now supports +/-13 and +/-14 as timezone offsets.
* Python: The most commonly used Hyper API types now have `__repr__()` methods and will return a string representation of the object when printed, making interactive exploring of the Hyper API more fun.
* Improved handling of spatial types:
* Parsing GEOGRAPHY values from well-known text (WKT) format automatically adjusts the order of vertices in polygons.
* Improved handling of geospatial types:
* Parsing GEOGRAPHY values from Well-known text (WKT) format automatically adjusts the order of vertices in polygons.
* During WKT parsing, additional vertices may be added to more closely resemble the original shape specified in the WKT.

* Adds several SQL functions for managing spatial data:
* Adds several SQL functions for managing geospatial data:
* For creating geography objects (`geo_make_point` and `geo_make_line`).
* For performing calculations on geography objects (`geo_distance` and `geo_buffer`).
* For manipulating the vertex order of polygons in geography objects (`geo_auto_vertex_order` and `geo_invert_vertex_order`). These functions can be used to address problems (for example, with spatial joins or to automatically zoom) where data comes from a source that uses a different winding order for polygons than the one used by Tableau. In Tableau, the interior of the polygon is considered to be on the left of the path drawn by points of the polygon ring.

* Prepared queries gained support for parallelized execution. See [PREPARE](/docs/sql/command/prepare) and [EXECUTE](/docs/sql/command/execute) for more information on prepared queries in Hyper.
* Java: Fixed crashes that could occur when inserting more than 16 MB of data into a table.

* The Hyper API `Inserter` class now allows SQL expressions to compute or transform data on the fly during insertion.

* The Hyper API `Inserter` class now allows inserting Well-known text (WKT) into `Geography` columns. You can use the `CAST` expression to transform WKT data to the `Geography` type and provide WKT data as a string to the `Inserter` class.
