Changelog

Sourced from twig/twig's changelog.

3.27.1 (2026-05-30)

• Fix array access with a Stringable key to coerce the key to string consistently instead of throwing in the optimized path

3.27.0 (2026-05-27)

• Add a strict mode to Twig\Sandbox\SecurityPolicy to opt-in to the 4.0 behavior for the extends/use tags and the parent/block/attribute functions, which are otherwise still implicitly allowed in a sandbox
• Deprecate the fact that the parent, block, and attribute functions are always allowed in a sandboxed template
• Fix sandbox filter/tag/function allow-list bypass when the sandbox state changed between renders of a cached Template instance
• Fix PHP 8.1+ implicit float-to-int deprecation triggered by sandboxed ArrayAccess attribute access with a float key
• Restrict allowed classes in Twig\Profiler\Profile::unserialize() to prevent arbitrary class instantiation
• Escape root profile name in HtmlDumper
• Fix sandbox bypass in deprecated internal wrappers twig_array_some(), twig_array_every(), and twig_check_arrow_in_sandbox() (src/Resources/core.php)
• Deprecate the Twig\Sandbox\SourcePolicyInterface interface with no replacement
• Fix sandbox bypass in the "column" filter when sandboxing is enabled via SourcePolicyInterface
• Fix sandbox __toString bypass via Traversable arguments to the join and replace filters (also covers containers that implement both Stringable and Traversable)
