Mustache.php v3.x drops support for PHP 5.2–5.5, but is otherwise backwards compatible with v2.x.

To ease the transition, previous behavior can be preserved via configuration:

• Thestrict_callables config option now defaults totrue. Lambda sections should use closures or callable objects. To continue supporting array-style callables for lambda sections (e.g.[$this, 'foo']), setstrict_callables tofalse.
• A context shadowing bug from v2.x has been fixed, but if you depend on the previous buggy behavior you can preserve it via thebuggy_property_shadowing config option.
• By default the return value of higher-order sections that are rendered via the lambda helper will no longer be double-rendered. To preserve the previous behavior, setdouble_render_lambdas totrue.This is not recommended.

New

• \Mustache_Engine and other prefixed classnames are all available as\Mustache\Engine, etc. You can keep using the old style for now, if you feel nostalgic for 2008, but you'll want to update eventually.
• Adds support for the Mustachedynamic tag names spec for partials and interpolation.

Improved

• The{{% BLOCKS }} pragma is now part of the Mustache spec, and is enabled by default.
• Optional Mustache specs (lambdas,inheritance, anddynamic_names) can now be disabled via config options.
• No more warnings or errors in PHP 8.x (thanks@reedy,@swissspidy, and everyone else who helped with this!).
• Improved resolution of complicated combinations of filters, dotted name lookups, and lambdas.
• Remove autoloader implementation. Just use Composer.
