1. Added spaceless filter that removes whitespace between HTML tags
2. Implemented {% apply filter %} ... {% endapply %} tag
3. Updated spaceless tag to use the spaceless filter internally
4. Fixed endverbatim tag handling
5. Added tests for all new functionality
The apply tag allows applying filters to blocks of content, which is the
modern recommended approach in Twig, replacing the deprecated spaceless tag.
