Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of nunjucks.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Release Notes

v3.0.1

• Fix handling methods and attributes of static arrays, objects and primitives. Solves the issue #937
• Add support for python-style array slices with Jinja compat enabled. Fixes #188; merge of #976.
• Fix call blocks having access to their parent scope. Fixes #906; merge of #994.
• Fix a bug that caused capturing block tags (e.g. set/endset, filter/endfilter) to write to the global buffer rather than capturing their contents. Fixes #914 and #972; merge of #990. Thanks Noah Lange.
