### [`v2.19.0`](https://github.com/binwiederhier/ntfy/releases/tag/v2.19.0)

[Compare Source](https://github.com/binwiederhier/ntfy/compare/v2.18.0...v2.19.0)

This is a fast-follow release that enables Postgres read replica support.

To offload read-heavy queries from the primary database, you can optionally configure one or more read replicas using the `database-replica-urls` option. When configured, non-critical read-only queries (e.g. fetching messages, checking access permissions, etc) are distributed across the replicas using round-robin, while all writes and correctness-critical reads continue to go to the primary. If a replica becomes unhealthy, ntfy automatically falls back to the primary until the replica recovers.

**Features:**

- Support [PostgreSQL read replicas](https://docs.ntfy.sh/config/#postgresql-experimental) for offloading non-critical read queries via `database-replica-urls` config option ([#&#8203;1648](https://github.com/binwiederhier/ntfy/pull/1648))
- Add interactive [config generator](https://docs.ntfy.sh/config/#config-generator) to the documentation to help create server configuration files ([#&#8203;1654](https://github.com/binwiederhier/ntfy/pull/1654))

**Bug fixes + maintenance:**

- Web: Throttle notification sound in web app to play at most once every 2 seconds (similar to [#&#8203;1550](https://github.com/binwiederhier/ntfy/issues/1550), thanks to [@&#8203;jlaffaye](https://github.com/jlaffaye) for reporting)
- Web: Add hover tooltips to icon buttons in web app account and preferences pages ([#&#8203;1565](https://github.com/binwiederhier/ntfy/issues/1565), thanks to [@&#8203;jermanuts](https://github.com/jermanuts) for reporting)
