12.1.0

12.1.0 (2024-05-01)

Enhancements

• Added an experimental API to update the base url for an application at runtime - App.UpdateBaseUriAsync(). This intended to be used for roaming between edge server and cloud. (Issue #3521)

Fixed

• The returned value from MongoClient.Collection.FindOneAsync is now a nullable document to more explicitly convey that null may be returned in case no object matched the filter. (PR #3586)
• Fixed crash when integrating removal of already removed dictionary key. (Core 14.5.2)
• App.AllUsers included logged out users only if they were logged out while the App instance existed. It now always includes all logged out users. (Core 14.6.0)
• Fixed several issues around encrypted file portability (copying a "bundled" encrypted Realm from one device to another): (Core 14.6.0)
  • Fixed Assertion failed: new_size % (1ULL << m_page_shift) == 0 when opening an encrypted Realm less than 64Mb that was generated on a platform with a different page size than the current platform.
  • Fixed a DecryptionFailed exception thrown when opening a small (<4k of data) Realm generated on a device with a page size of 4k if it was bundled and opened on a device with a larger page size.
  • Fixed an issue during a subsequent open of an encrypted Realm for some rare allocation patterns when the top ref was within ~50 bytes of the end of a page. This could manifest as a DecryptionFailed exception or as an assertion: encrypted_file_mapping.hpp:183: Assertion failed: local_ndx < m_page_state.size().
• Schema initialization could hit an assertion failure if the sync client applied a downloaded changeset while the Realm file was in the process of being opened. (Core 14.6.0)
• Improve perfomance of "chained OR equality" queries for UUID/ObjectId types and RQL parsed "IN" queries on string/int/uuid/objectid types. (Core 14.6.0)
• Fixed a bug when running a IN query (or a query of the pattern x == 1 OR x == 2 OR x == 3) when evaluating on a string property with an empty string in the search condition. Matches with an empty string would have been evaluated as if searching for a null string instead. (Core 14.6.1)

Compatibility

Internal
