    Compatibility notes:

    • 👀 Depthed paths are now conditionally pushed on to the stack. If the helper uses the same context, then a new stack is not created. This leads to behavior that better matches expectations for helpers like if that do not seem to alter the context. Any instances of ../ in templates will need to be checked for the correct behavior under 4.0.0. In general templates will either reduce the number of ../ instances or leave them as is. See #1028.
    • The = character is now HTML escaped. This closes a potential exploit case when using unquoted attributes, i.e. <div foo={{bar}}>. In general it's recommended that attributes always be quoted when their values are generated from a mustache to avoid any potential exploit surfaces.
    • AST constructors have been dropped in favor of plain old javascript objects
    • The runtime version has been increased. Precompiled templates will need to use runtime of at least 4.0.0.
