Changelog

1.0.0-Beta.9

  • [ADDED] Enabled Full Text Search on iOS platforms. An example implementation is not yet available, however our JavaScript implementations can be used as a guide in the mean time, or reach out to us on Discord. (PR #145)

  • [ADDED] For advanced use cases: The ability to update the schema for existing PowerSync clients using updateSchema(). (PR #154)

  • [IMPROVED] Unified concurrency model across platforms by introducing a pool of read connections and a single write connection, simplifying driver implementation and enabling concurrent reads. This also brings the architecture in line with other PowerSync SDKs. (PR #145)

  • [IMPROVED] Added queuing protection and warnings when connecting multiple PowerSync clients to the same database file, avoiding inconsistent state issues and improving the reliability of watched queries. (PR #146)

  • [IMPROVED] Switched to statically linking SQLite on native platforms since dynamic extension loading is disabled on Apple platforms. (PR #147)

  • [FIXED] A bug where local only, insert only and view name overrides were not applied for schema tables. (PR #154)

  • [FIXED] Updated powersync-sqlite-core to v0.3.12, which fixes powersync_last_synced_at() returning stale information. 

1.0.0-Beta.8

  • [ADDED] Support for sync bucket priorities to sync critical data first. Learn more.

  • [ADDED] The ability to throttle watched queries via the optional throttleMs parameter. This will prevent these queries from re-running within the specified duration and therefore reduce the load for frequently updating tables.

  • [IMPROVED] Internally improved the query logic for watch() queries, by optimizing table update handling, enhancing thread safety, and simplifying the implementation (see the PR).

  • [FIXED] The uploading and downloading Sync Status indicators not correctly emitting status events.

1.0.0-Beta.7

  • [FIXED] An issue where throwing exceptions in the query mapper could cause a runtime crash.

  • [IMPROVED] Internally improved type casting.

  • [IMPROVED] Internals of the watch() query.

1.0.0-Beta.6

  • [BREAKING CHANGE]: watch queries are now throwable and therefore will need to be accompanied by a try e.g.

try database.watch()

  • [BREAKING CHANGE]: transaction functions are now throwable and therefore will need to be accompanied by a try e.g.

try await database.writeTransaction { transaction in
  try transaction.execute(...)
}

  • [IMPROVED] Allow execute errors to be handled

  • [IMPROVED]userId is now set to nil by default and therefore it is no longer required to be set to nil when instantiating PowerSyncCredentials and can therefore be left out.

1.0.0-Beta.5

  • [IMPROVED] Error handling for errors originating in the Kotlin SDK.

  • [IMPROVED] __fetchCredentials to log the error but not cause an app crash on error.

1.0.0-Beta.4

  • [IMPROVED] Ability to use the column name to get the pertaining value when using the cursor instead of having to use the index number. The following functions now accept a column name parameter: getBoolean,getBooleanOptional,getString,getStringOptional, getLong,getLongOptional, getDouble,getDoubleOptional.

  • BREAKING CHANGE: This should not affect anyone, but we made KotlinPowerSyncCredentials, KotlinPowerSyncDatabase and KotlinPowerSyncBackendConnector private as these should never have been public.

1.0.0-Beta.3

  • BREAKING CHANGE: Updates the underlying powersync-kotlin package to BETA18.0 which requires transactions to become synchronous as opposed to asynchronous.

    • Previously:

      try await database.writeTransaction { transaction in
  try await transaction.execute(
    sql: "INSERT INTO users (id, name, email) VALUES (?, ?, ?)",
    parameters: ["1", "Test User", "test@example.com"]
  )
}

      Now:

      try await database.writeTransaction { transaction in
  transaction.execute( // <- This has become synchronous
    sql: "INSERT INTO users (id, name, email) VALUES (?, ?, ?)",
    parameters: ["1", "Test User", "test@example.com"]
  )
}

1.0.0-Beta.2

  • [FIXED] Updated powersync-sqlite-core to v0.3.8, which fixes a view migration issue (see details).

  • [IMPROVED] Increase maximum amount of columns from 63 to 1999.

1.0.0-Beta.1
