Release notes

This is a release candidate for the next feature release of Drupal 8. Release candidates are not supported for production sites, but they are intended for widespread testing in preparation for the upcoming stable release. More information on release candidates.

Minor releases provide new improvements and functionality without breaking backward compatibility (BC) for public APIs. Note that there may be changes in internal APIs and experimental modules that require updates to contributed and custom modules and themes per Drupal core's backwards compatibility and experimental module policies.

For a full list of the API and feature additions included in the 8.3.0 release candidate, see the 8.3.0-alpha1, and 8.3.0-beta1 release notes.

Translators should take note of the string changes since the last minor release. Developers can review the change records for this release.

Backwards compatibility break to correct Serialization module output

#2751325: All serialized values are strings, should be integers/booleans when appropriate corrects a bug that would output all scalar values as strings rather than the correct data type in serialized output, including REST responses. This fix may require some client application updates if the application relies on these values being strings.

An opt-in backwards compatibility mode is configurable at the site level, but not enabled by default. Read the change record for more information on this change and on configuring the backwards compatibility mode.

Other important issues resolved since 8.3.0-beta1
