+## 1.0.0
+
+- Start using stable version range.
+
+## 0.4.2
+
+- Improve HTTP error messages.
+- Enable SQLite recursive triggers.
+- Support overriding view names.
+- Validate schema definitions for duplicates.
+
+## 0.4.1
+
+- Use Apache 2.0 license.
+- Update uuid dependency.
+
+## 0.4.0
+
+Improvements:
+
+- Some parameters to `PowerSyncCredentials` are now optional.
+- Upgrade dependencies.
+
+## 0.4.0-preview.6
+
+New functionality:
+
+- Include transaction ids on crud entries, allowing transactions to be grouped together.
+- Simplify implementation of `PowerSyncBackendConnector` by automatically handling token caching.
+
+Fixes:
+
+- Only check token expiration on the server, avoiding issues when the local time is out of sync.
+- Fix some edge case errors that would kill the sync Isolate.
+- Fix errors when disconnecting shortly after connecting.
+
+Breaking changes:
+
+- `PowerSyncDatabase.disconnect()` now returns `Future<void>` instead of `void`.
+- Subclasses of `PowerSyncBackendConnector` must now implement `fetchCredentials()` instead of `refreshCredentials()` + `getCredentials()`.
+
+Other changes:
+
+- Update sqlite_async dependency to 0.4.0: <https://pub.dev/packages/sqlite_async/changelog>
+
+## 0.3.0-preview.5
+
+- Link github repository.
+
+## 0.3.0-preview.4
+
+The low-level SQLite-related code is extracted into a separate [sqlite_async](https://pub.dev/packages/sqlite_async) package.
+`sqlite_async` handles the the database connection, connection pooling, Isolate management, queries,
+transactions, default options, watching, and migrations.
+
+The `powersync` package now just adds automatic sync and dynamic schema management on top. This makes it easy to switch between
+using PowerSync, or just using a local database directly.
+
+Breaking changes:
+
+- `TableUpdate` renamed to `UpdateNotification`.
+- `PowerSyncDatabase.connectionFactory()` renamed to `PowerSyncDatabase.isolateConnectionFactory()`,
+   and should only be used to pass the connection to a different isolate.
+- All tables apart from `ps_crud` are dropped and re-created when upgrading to this version.
+   This will not result in any data loss, but a full re-sync is required.
+
+Fixes:
+
+- Fix queries not watching the correct tables in some cases.
+- Fix performance issues on bulk insert/update/delete.
+
+Other changes:
+
+- Views and triggers are now persisted in the database, instead of using temporary views.
+  - This allows reading the views using other tools.
+  - It is still not possible to update the views using other tools, since triggers use the custom `powersync_diff` function to compute changes.
+
+## 0.2.0-preview.3
+
+- Use new write checkpoint API for reduced latency on data upload.
+- Improve consistency when custom primary keys are used.
+- Fix error on `getOptional()`.
+- Use `gen_random_uuid()` as an alias for `uuid()` (custom function for SQLite).
+
+## 0.2.0-preview.2
+
+- Performance improvements in downloading changes.
+
+## 0.2.0-preview.1
+
+Breaking change:
+
+- Rename internal tables to all start with `ps_`. All existing local data is deleted and re-synced.
+
+Other changes:
+
+- Add support for local indexes.
+- Add support for local-only tables - no changes recorded, and not synced with the remote service.
+- Add support for insert-only tables - records changes, but does not persist data or download from the remote service.
+- Add `executeBatch()` API: execute the same statement with multiple parameter sets.
+- Add `computeWithDatabase()` API: execute a function in the database isolate, with low-level synchronous database access.
+- Add `onChange()` call to receive notifications of changes to a set of tables.
+- Improve `watch()` to only listen for updates to relevant tables.
+- Faster `uuid()` implementation.
+
+## 0.1.1-preview.2
+
+- Require Flutter SDK.
+
+## 0.1.1-preview.1
+
+- First public version.

+# PowerSync SDK for Dart/Flutter
+
+[PowerSync](https://powersync.co) is a service and set of SDKs that keeps PostgreSQL databases in sync with on-device SQLite databases.
+
+## SDK Features
+
+* Real-time streaming of changes.
+* Direct access to the SQLite database - use SQL on the client and server.
+* Operations are asynchronous by default - does not block the UI.
+* Supports one write and many reads concurrently.
+* No need for client-side database migrations - these are handled automatically.
+* Subscribe to queries for live updates.
+
+## Getting started
+
+```dart
+import 'package:powersync/powersync.dart';
+import 'package:path_provider/path_provider.dart';
+import 'package:path/path.dart';
+
+const schema = Schema([
+  Table('customers', [Column.text('name'), Column.text('email')])
+]);
+
+late PowerSyncDatabase db;
+
+openDatabase() async {
+  final dir = await getApplicationSupportDirectory();
+  final path = join(dir.path, 'powersync-dart.db');
+  // Setup the database.
+  db = PowerSyncDatabase(schema: schema, path: path);
+  await db.initialize();
+
+  // Run local statements.
+  await db.execute(
+      'INSERT INTO customers(id, name, email) VALUES(uuid(), ?, ?)',
+      ['Fred', '[email protected]']);
+}
+
+connectPowerSync() async {
+  // DevConnector stores credentials in-memory by default.
+  // Extend the class to persist credentials.
+  final connector = DevConnector();
+
+  // Login in dev mode.
+  await connector.devLogin(
+      endpoint: 'https://myinstance.powersync.co',
+      user: 'demo',
+      password: 'demo');
+
+  // Connect to PowerSync service and start sync.
+  db.connect(connector: connector);
+}
+```
