2.10 Migration Guide¶

Using undefined CLI options will now result in an error. This behavior has been backported from 3.x

The CONFIG constant was added. This constant defaults to app/Config, and is intended to increase forwards compatibility with 3.x

New internal data types were added for smallinteger and tinyinteger. Existing SMALLINT and TINYINT columns will now be reflected as these new internal data types. TINYINT(1) columns will continue to be treated as boolean columns in MySQL.

Model::find() now supports having and lock options that enable you to add HAVING and FOR UPDATE locking clauses to your find operations.

TranslateBehavior now supports loading translations with LEFT JOIN. Use the joinType option to use this feature.

SecurityComponent now emits more verbose error messages when form tampering or CSRF protection fails in debug mode. This feature was backported from 3.x

SecurityComponent will blackhole post requests that have no request data now. This change helps protect actions that create records using database defaults alone.

FlashComponent now stacks messages of the same type. This is a feature backport from 3.x. To disable this behavior, add 'clear' => true to the configuration for FlashComponent.

PaginatorComponent now supports multiple paginators through the queryScope option. Using this option when paginating data will force PaginatorComponent to read from scoped query parameters instead of the root query string data.

HtmlHelper::image() now supports the base64 option. This option will read local image files and create base64 data URIs.

HtmlHelper::addCrumb() had the prepend option added. This lets you prepend a breadcrumb instead of appending to the list.

FormHelper creates ‘numeric’ inputs for smallinteger and tinyinteger types.

Router::reverseToArray() was added.
