+## 0.20.0 (unreleased)
+
+ - Add an `id` attribute to form fields in the [form](https://sql.ophir.dev/documentation.sql?component=form#component) component. This allows you to easily reference form fields in custom javascript code.

 ## 0.19.1 (2024-02-28)
   - **SECURITY**: fixes users being able to re-run migrations by visiting `/sqlpage/migrations/NNNN_name.sql` pages. If you are using sqlpage migrations, your migrations are not idempotent, and you use the default SQLPAGE_WEB_ROOT (`./`) and `SQLPAGE_CONFIGURATION_DIRECTORY` (`./sqlpage/`), you should upgrade to this version as soon as possible. If you are using a custom `SQLPAGE_WEB_ROOT` or `SQLPAGE_CONFIGURATION_DIRECTORY` or your migrations are idempotent, you can upgrade at your convenience.
  - Better error messages on invalid database connection strings. SQLPage now displays a more precise and useful message when an error occurs instead of a "panic" message.
