v4.6.0
This release only includes changes for the ChirpStack Gateway OS Full (Raspberry Pi) and the RAK7391 (Raspberry Pi CM4) images.
Features
PostgreSQL > SQLite migration
This release replaces the ChirpStack PostgreSQL database with SQLite. By migrating to SQLite, PostgreSQL is no longer required and thus reducing the dependencies. It also makes it easier to create backups as the SQLite database is stored as a single file (/srv/chirpstack/chirpstack.sqlite).
Before you upgrade
Before you upgrade, you should migrate the data to SQLite first, as after upgrading the PostgreSQL binaries will no longer be available. To migrate ChirpStack data, you can use the migration utility (for ARMv7) that will automatically create the SQLite database and migrate the data.
You must download the .ipk package from [Releases · chirpstack/chirpstack-pg-to-sqlite · GitHub (Releases · chirpstack/chirpstack-pg-to-sqlite · GitHub). In the ChirpStack Gateway OS v4.5.x web-interface, navigate to System > Software click the Upload package… button and upload the .ipk package. After uploading it will immediately initialize the SQLite database and print the status of the migration.
