Release Date: 2019-12-18 // over 4 years ago

  • 🚀 Released December 18, 2019 • diff

    🆕 New

    • #656: Type inference of selected columns
    • #659: Database interruption
    • 🔒 #660: Database Lock Prevention
    • ⬆️ #662: Upgrade custom SQLite builds to version 3.30.1 (thanks to @swiftlyfalling)
    • #668: Database Suspension

    💥 Breaking Changes

    📚 [Custom SQLite builds](Documentation/CustomSQLiteBuilds.md) now disable by default the support for the Double-quoted String Literals misfeature. This is a technically a breaking change, but it fixes an SQLite bug. You can restore the previous behavior if your application relies on it:

    // Enable support for the Double-quoted String Literals misfeature
var configuration = Configuration()
configuration.acceptsDoubleQuotedStringLiterals = true
let dbQueue = try DatabaseQueue(path: ..., configuration: configuration)

    📚 Documentation Diff

    The new [Interrupt a Database](README.md#interrupt-a-database) chapter documents the new interrupt() method.

    📚 The new [Sharing a Datatase in an App Group Container](Documentation/AppGroupContainers.md) guide explains how to setup GRDB when you share a database in an iOS App Group container.
