Release Notes

mitsuhiko/minijinja (minijinja)

v2.8.0

Compare Source

• Added SemiStrict undefined mode that is like strict but allows
  to be checked for truthiness. Additionally an if expression without
  an else block will always produce a silent undefined object that
  never errors for compatibility with Jinja2. #​687
• Make the trait bounds of ViaDeserialize stricter. Now the type
  can only be constructed if the type implements DeserializeOwned.
  This is not a new requirement for passing the function to
  add_function but bad code will now error earlier for better
  error reporting. #​689
• Raise MSRV to 1.70.
• The contrib crate now uses a basic xorrand implementation instead
  of depending on all of the rand module. #​696
• Added temps, a way to stash away temporary state during rendering. #​697
• Fixed a bug that caused the random functions in the contrib crate
  to not advance the RNG between calls. #​698
• Added Environment.undeclared_variables_in_template and
  Environnent.undeclared_variables_in_str to Python binding. #​699
• Enable loop_controls for Python in-line with the CLI. #​704
• Fixed a panic when comparing plain objects. #​705
• Added Object::custom_cmp to allow objects to influence how they
  compare against themselves. This also fixes Python objects in the
  Python binding not to compare correctly. #​707
• Fixed a bug where undeclared_variables would incorrectly handle
  variables referenced by macros. #​714
• Fixed a deadlock in the Python binding when multiple threads were
  rendering from the same environment at once. #​717
• The Python bindings handle __bool__ correctly now for custom
  objects in if-conditions and filters. #​719
• Fixed a bug where }} caused a syntax error in expressions with
  open parentheses, braces or brackets. #​723
• Added State::known_variables to return a list of known variables
  and Environment::globals. #​724
• Fixed an issue with undeclared variables not handling caller. #​725
• Removed unnecessary Filters and Tests traits. They remain as
  hidden aliases to Function. #​726
• Fixed a bug that caused implicit string concatenation to not correctly
  handle escapes. #​728
• Implemented constant folding in the code generator. #​731
• Improved error reporting for bad loop recursion calls. #​734
• The engine now uses smaller integers to represent columns, line numbers
  and addresses. This cuts down on the memory usage needed for debug
  information. #​735
• Added load_from_path to python. #​736
• Added JavaScript bindings. #​737
