1.0.5

bugfix:

• more work on handling errors, including fixing #133 and adding more comprehensive tests for #129 and #132

1.0.4

bugfix:

• fix error handling that might result in null exception

1.0.3

bug fixes, a few feature enhancements:

• functions ("Procedures") defined within asteval have a _signature() method, now use in repr
• add support for deleting subscript
• nested symbol tables now have a Group() function
• update coverage config
• cleanups of exception handling : errors must now have an exception
• several related fixes to suppress repeated exceptions: see GH #132 and #129
• make non-boolean return values from comparison operators behave like Python - not immediately testing as bool

1.0.2

bug fixes:

• fix NameError handling in expression code
• make exception messages more Python-like

1.0.1

security fixes, based on audit by Andrew Effenhauser, Ayman Hammad, and Daniel Crowley, IBM X-Force Security Research division

• remove numpy modules polynomial, fft, linalg by default for security concerns
• disallow string.format(), improve security of f-string evaluation

1.0.0

Asteval 1.0.0

Asteval has been fairly mature for a while, with major improvements since version 0.9.29 over the past year or so making it feel like it has reached a point where the features and API are stable enough to call version 1.0.0.

Changes compared to 0.9.33:

• fix (again) nested list comprehension (Issues #127 and #126).
• add more testing of multiple list comprehensions.
• more complete support for Numpy 2, and removal of many Numpy symbols that have been long deprecated.
• remove AST nodes deprecated in Python 3.8.
• clean up build files and outdated tests.
• fixes to codecov configuration.
• update docs.

0.9.33

Fixes:

• fixes for multiple list comprehensions (addressing #126)
• add testing with optionally installed numpy_financial to CI
• test existence of all numpy imports to better safeguard against missing functions (for safer numpy 2 transition)
• update rendered doc to include PDF and zipped HTML

0.9.32

• add deprecations message for numpy functions to be removed in numpy 2.0 (#122)
• comparison operations use try/except for short-circuiting instead of checking for numpy arrays (addressing #123)
• add Python 3.12 to testing
• move repository from "newville" to "lmfit" organization
• update doc theme, GitHub locations pointed to by docs, other doc tweaks.

0.9.31

• cleanup numpy imports to avoid deprecated functions, add financial functions from numpy_financial module, if installed.
• prefer 'user_symbols' when initializing Interpreter, but still support 'usersyms' argument. Will deprecate and remove eventually.
• add support of optional (off-by default) "nested symbol table", based on a Group object that can be accessed from Python either with dict syntax (ie aeval.symtable['x']) or with object attribute access (aeval.symtable.x). In addition, symbols can be found by looking first in the top-level symbol table and then in sub-Groups named in symtable._searchgroups, allowing for a more hierarchical, nested symbol table. This should be considered experimental and is off by default. The make_symbol_table() function gains a nested=False argument to control whether to use this option.
• update tests to run most tests with symbol tables of dict and nested group type.
• general code and testing cleanup.

0.9.30

• add config argument to Interpreter to more fully control which nodes are supported
• add support for import and importfrom -- off by default
• add support for with blocks
• add support for f-strings
• add support of set and dict comprehension
• fix bug with 'int**int' not returning a float.
