## [Unreleased]

## [1.3.1] - 2026-04-19

## [1.3.0] - 2025-10-29

- Drops support for Python 3.9; adds support for Python 3.14.
- This project is now built using uv.

## [1.2.1] - 2025-09-12

- Fixes a bug where Harlequin would crash if you execute a query against a closed/lost database connection ([#42](https://github.com/tconbeer/harlequin-postgres/issues/42)).

## [1.2.0] - 2025-02-27

- Adds interactions to list relations, indexes, constraints, and to describe relations (similar to psql's `\d+`) ([tconbeer/harlequin#586](https://github.com/tconbeer/harlequin/discussions/586) - thank you [@JPFrancoia](https://github.com/JPFrancoia)!).

## [1.1.1] - 2025-02-05

## [1.1.0] - 2025-01-27
