This is an early preview of some of the breaking changes in the upcoming 0.3.0 release.

New Features

- New API: instead of taking in single characters, the `_feed` function now takes in blocks of characters at once, to improve efficiency
- `end` support is now optional. This is part of the API changes, because now end handling is through a separate `_end` function.
- Fallthrough semantics: the `else` path of a `case` node, as well as jumps into `catch` blocks no longer consume a character, and instead
properly forward it to the first match in the target block.

Infrastructure Changes

- NMFU now also builds AppImages

This is a minor bugfix release with a few new features

New Features

- New option `-fuse-cplusplus-guard` which makes the generated headers C++ compatible

Bugs Fixed

- Previously, a try-except block with an empty handler would cause an error; now it correctly does nothing and exit on an error.

This is a feature release which adds hooks and a few miscellaneous features.

New Features

- Hooks:
- Parsers can now call arbitrary callbacks at arbitrary points like macros
- These hooks get a pointer to the current state and input character
- In the future, these may be used for things like buffering large outputs
- Append-character expressions
- Append expressions can now add individual character codes from a math expression
- e.g: `out_var += [$last - 3];`

Bugs Fixed

- Case labels with inverted character classes (or non-erroring Else transitions) would accept too few inputs
- Macros with more than one statement would be truncated
- Custom Else transitions were not properly dealt with by the ambiguous detection logic and so a variety of things involving wildcards would fail in strange ways.

Infrastructure Changes

- NMFU now has a test suite, install the necessary dependencies with the `tests` extra and run with `pytest`
- NMFU now has CI, see the badge in the README
- NMFU can now build as a snap

This is a release candidate for the upcoming 0.2.0 release. A full changelog will be written when it is released proper.

General Summary

- Added hooks
- Added tests

This is a minor bugfix release to v0.1.

Bugs Fixed

- The grammar was incorrectly matching positive floating point or integer numbers when it should have been matching signed integers. Actual floating point support is yet to come.
