Changelog

Notable user-facing changes to Genzimnify are documented here. Entries are organized by release and follow the Added, Changed, Fixed, and Removed categories where applicable.

2.0.3 — 2026-09-27

Added

• gzim convert <file> --to <py|gzim> with sibling output, custom -o paths, explicit --force replacement, and source-file protection.
• A limited Python-to-Genzimnify preview using Python's AST parser, lexical builtin mapping, escaped conflicting names, and source-located errors for unsupported syntax. Conversion parses input without executing it and validates generated Genzimnify before writing.
• Conversion integration tests covering native and Python execution, overwrite protection, failure recovery, and CLI validation; Windows CI also runs the conversion suite.

Changed

• The new conversion command reuses Python export and stages output before replacement. Existing emit-python and build commands retain their behavior.

Preview limitations

• Python-to-Genzimnify conversion requires Python 3.8+ and supports a limited syntax subset. Imports, classes, decorators, async, comprehensions, and chained comparisons are not yet supported.
• Conversion normalizes formatting and does not preserve comments. Generated programs follow native Genzimnify semantics; conversion is not a lossless round trip.

See conversion commands and supported syntax and builtin forms for details.

2.0.2 — 2026-09-27

Changed

• The REPL now preserves session state while executing only newly submitted code, preventing earlier output and side effects from being replayed.
• Package updates are staged before installation and replace an existing dependency only after the new copy has been resolved successfully.
• CLI commands now reject unexpected trailing arguments instead of silently ignoring them.
• The runtime, language server, and Python emitter now use a shared native version constant.

Fixed

• Failed dependency additions now restore the previous project manifest, lockfile, and installed package.
• The Nimble package manifest now uses a valid dependency declaration and correctly maps the gzimlsp source module to the gzim-lsp executable.
• The Windows installer now uses a unique temporary archive path to avoid conflicts between concurrent installations.

Removed

• Prebuilt Intel Mac (macOS x86_64) artifacts are no longer published. Version 2.0.1 is the final Intel Mac release; macOS support now targets Apple Silicon.

Quality assurance

• Language-server integration tests now run in continuous integration.
• Windows CI now compiles and starts gzim-lsp.
• Release builds verify that the binary version matches the Git tag before artifacts are published.

2.0.1 — 2026-09-27

Added

• Introduced explicit Python interoperability through the py.* namespace, including positional and keyword arguments and JSON-compatible value conversion.
• Added project manifests, reproducible lockfiles, Git dependencies, local-path dependencies, and the add, install, remove, and packages commands.
• Added package-aware module resolution under .gzim/packages.
• Introduced the Genzimnify language mark and expanded Python-to-Genzimnify syntax comparisons.

Changed

• Reorganized the documentation and README around installation, language usage, tooling, packages, and interoperability.
• Replaced the documentation search modal with an inline search-results interface.

Fixed

• Corrected release version metadata and refined release documentation.

2.0.0 — 2026-09-26

Added

• Introduced the standalone gzim runtime, implemented in Nim and distributed as a native executable.
• Added native values, collections, functions, generators, classes, exceptions, local modules, file operations, and standard-library modules.
• Added gzim doctor for runtime and platform diagnostics.
• Added optional Python export through gzim emit-python.
• Added automated release archives, checksum generation, shell and PowerShell installers, and a Homebrew formula.

Changed

• Normal program execution moved from Python source generation to direct evaluation by the native runtime.
• gzim replaced genzimc as the primary user-facing command; the compiler remained available for compatibility and export workflows.
• Python was no longer required for ordinary Genzimnify programs.

1.1.0 — 2026-09-25

Added

• Replaced the original browser playground with Genzimnify Studio, including examples, live diagnostics, syntax highlighting, code completion, formatting, import and export, share links, autosave, themes, and a resizable console.
• Introduced the first full documentation portal and reorganized generated API documentation.
• Added regression coverage for invalid assignments, malformed control-flow blocks, parameter validation, argument ordering, multiline strings, and nested scopes.

Fixed

• Improved multiline string emission and nested-function scope validation.
• Improved compile-time diagnostics for invalid assignment targets, malformed try and match blocks, invalid parameter lists, and duplicate or misordered call arguments.
• Made language-server tests portable across development environments.

1.0.0 — 2026-09-22

Added

• Published the initial Genzimnify language implementation in Nim, including the lexer, parser, abstract syntax tree, semantic analyzer, Python emitter, source maps, and command-line interface.
• Introduced the core language: bindings and constants, control flow, functions and generators, collections and comprehensions, classes and inheritance, exceptions, pattern matching, context managers, asynchronous syntax, type annotations, modules, and glow strings.
• Added run, build, check, repl, and init workflows through genzimc.
• Added a Tree-sitter grammar, syntax-highlighting queries, gzim-lsp, and a Zed development extension.
• Added the original static browser playground, powered by the JavaScript transpiler and Pyodide.
• Added language, compiler, and language-server test suites together with prebuilt development binaries.

Runtime model

• Version 1.0 transpiled .gzim source to Python and required Python 3.10 or newer to execute programs.
