[!NOTE] In order to maintain a wide PHP version support range, there are minor changes to a few interfaces, which you might need to handle if you extend Mustache (see c0453be).

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 Mustache dynamic 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, and dynamic_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.
