1.25.0

New Features

• Dart — discover .dart files and analyze functions, methods, getters, setters, and constructors with bodies, including expression bodies and async/generator modifiers; handle raw and triple-quoted strings, null-safety operators, exception clauses, and switch-expression arms
• COBOL — discover .cbl, .cob, and .cobol files in fixed format, report Procedure Division paragraphs as functions, and count core conditional, loop, and selection decisions

Bug Fixes

• JavaScript, TypeScript, JSX, and TSX: preserve callback boundaries and CCN when call arguments or object values contain subscripts, including e(r[0]) and return {w: [m[n - 1]]} (issue #524, PR #525)
• JavaScript, TypeScript, JSX, and TSX: end expression-bodied arrows at their enclosing argument, array, or object comma so following object members retain their own functions and metrics (issue #524, PR #525)
• JavaScript, TypeScript, JSX, and TSX: preserve runtime functions across object bodies, ternary branches, multiline expressions, and immediately invoked functions (PRs #531, #533, #534)
• JavaScript and TypeScript: distinguish runtime labeled blocks from type annotations; keep nested type brackets, function-type fields, assertions, and enclosing runtime delimiters from swallowing or inventing functions (issue #524, PR #548)
• JavaScript and TypeScript: preserve arrow and callback parameters, including names containing _ or $, type-keyword names, and empty destructuring slots; exclude TypeScript's this receiver from the parameter count and use the same count in text, CSV, HTML, and Checkstyle output (PRs #532, #535, #536, #537)
• JavaScript, TypeScript, JSX, and TSX: count conditions inside nested template interpolations and unspaced ternaries, while keeping optional parameter/member markers and keyword-named properties from adding false decisions (PRs #545, #546, #547)
• JavaScript and TypeScript: distinguish regex literals from division after keywords and arrows, and end line comments at the newline even after a trailing backslash (PRs #528, #544)
• Vue: preserve original source line numbers when filtering script blocks, and recognize TypeScript annotations in typed script blocks
• Python -ENS: count nested control structures by indentation, including async statements and match, without treating comprehensions or conditional expressions as nested statements (PR #527)

Improvements

• Verify Python 3.8 through 3.14 on Linux and Windows in CI and update the supported-version documentation and package classifiers
