v0.4.0-preview

Fixed

• Primary keys could be changed after an object was inserted (since 0.1.0)
• Using a property type of vector of enums would cause a compilation error (since 0.1.0).
• Fixed a bug preventing SSL handshake from completing successfully due to failed hostname verification when linking against BoringSSL. (PR #7034)

Enhancements

• The Sync metadata Realm is now encrypted by default on Apple platforms unless the REALM_DISABLE_METADATA_ENCRYPTION environment variable is set.
  To enable encryption on the metadata Realm on other platforms you must set an encryption key on realm::App::configuration.

std::array<char, 64> example_key = {...};
realm::App::configuration app_config;
app_config.app_id = ...
app_config.metadata_encryption_key = example_key;
auto encrypted_app = realm::App(app_config);

• Add ability to encrypt a Realm. Usage: realm::config::set_encryption_key(const std::array<char, 64>&).
• Add support for std::set in object models.

Breaking Changes

• realm::App(const std::string &app_id, const std::optional<std::string> &base_url, const std::optional<std::string> &path, const std::optional<std::map<std::string, std::string>> &custom_http_headers) has been deprecated.
  use realm::App(const realm::App::configuration&); instead.

Compatibility

• Fileformat: Generates files with format v23. Reads and automatically upgrade from fileformat v5.

Internals

• Upgraded to Core v13.23.1
