Releases: brython-dev/brython
Brython-3.14.0
This release implements most of the changes in Python 3.14, notably Template Strings (PEP 750) and Deferred evaluation of annotations (PEP 649 and 749).
Brython-3.13.2
This is mostly a bugfix release, with a few changes in the generated Javascript code.
Brython-3.13.1
Many important changes in this version:
- major change in functions implementation, resulting in a significant performance improvement and better compliance with Python attribute resolution
- major performance improvement also in class creation
- indentation of generated Javascript code
- rewriting of error reporting, compliant with PEP 657
- rewriting of the zlib module, now much faster
Brython-3.13.0
This is the first release of Brython 3.13, including the new features of Python 3.13.
Brython-3.12.5
There is no new feature in this version, only bug fixes and internal implementation changes.
Brython-3.12.4
This is mostly a bugfix release with no significant new feature.
Brython-3.12.3
The main feature in this release is the replacement of the Python parser by a program generated from the standard Python grammar with the CPython toolchain, adapted to generate Javascript code instead of C.
Austin Schick greatly contributed to this change by providing a first proof of concept in issue #2354 and advice on the next steps of the implementation.
(This is the same as 3.12.2, with a fix for the blocking bug #2381)

Brython-3.12.1
Special thanks to Denis Migdal, who inspired and/or wrote the main changes in this release:
- speed up startup time by removing generation of Unicode-related tables
- significant improvement in performance of function argument parsing
- rewrite frames management
Apart from many bug fixes, other changes include:
- an improved implementation of PEP 695 – Type Parameter Syntax
- a partial rewriting of the alterative Brython implementation using a PEG parser with the standard Python grammar
Brython-3.12.0
The main new features in this release are:
- the implementation of Python 3.12, notably:
- PEP 701, f-strings in the grammar
- PEP 695, type parameter syntax and the type statement
- Improved ‘Did you mean …’ suggestions for NameError and SyntaxError exceptions
-
the optional removal of the attribute
onload = brython(options)of the<body>tag, replaced by setting page-level options with tag<brython-options>or per-script options as attributes of the<script>tag -
a more consistent interface between Brython and Javascript
