• Add trim_start, trim_end, trim_start_matches and trim_end_matches filters
• Allow blocks in filter sections

• Add Tera::render_str, like Tera::one_off but can use an existing Tera instance

• Length filter now errors for things other than array, objects and strings. The fact that it was returning 0 before for other types was something that should have been fixed before 1.0 but got forgotten and was considered a bug.

• Fix filter sections not keeping whitespaces
• The filesizeformat filter now takes a usize instead of a i64: no changes to behaviour

Breaking changes

• Now requires Rust 1.34
• Removed error-chain errors and added rich Error enum instead
• Filter, Tester and Function are now traits and now take borrowed values instead of owned
• Updated for 2018 edition
• Require macros import to be at the top of the files along with extends as it is fairly cheap and the code already only really look there.
• Enforce spacing in tags at the parser, before ifsomething was considered ok
• Pluralize filter now uses singular and plural arguments instead of suffix
• Add a test for checking whether a variable is an object
• Escaping now happens before inserting the final result of an expression: no need anymore to add | safe everywhere, only at the last position
• Remove safe argument of the urlencode filter, / is still escaped by default
• The compile_templates! macro has been removed
