# Changelog ## 0.2.0 - Makes canonical `.0` text the native source surface, with a parser, formatter, Program import path, diagnostics, docs, examples, stdlib sources, benchmarks, conformance fixtures, and command snapshots aligned around that format. - Promotes ProgramGraph from inspection output into an editable artifact workflow with deterministic dump, validate, view, check, roundtrip, import, patch, build, run, test, size, and package entrypoint support. - Adds source-backed graph edits so checked graph patches can rewrite canonical `.0` files while preserving package/import context, std helper context, metadata, and stable graph identities. - Expands direct backend coverage with darwin-x64 Mach-O executable support, shared AArch64 ELF/COFF emission, target-readiness reporting, byte-view ABI fixes, and stronger cross-target buildability checks. - Adds source-backed `std.path`, `std.str`, and `std.math` modules with docs, examples, Rosetta coverage, and direct target validation. - Exposes resolved call-resolution and stdlib helper facts in graph JSON, tightening generic return typing, member call facts, std helper validation, and package cache metadata. - Grows Rosetta and compiler smoke coverage, graph command contracts, metrics budgets, CLI docs, skills, and docs tests around the current agent edit loop. ### Contributors - @ctate ## 0.1.4 - Adopts canonical `.0` text as the current Zero source surface across parsing, import resolution, package manifests, command workflows, docs, fixtures, formatting, and artifact contracts. - Rebuilds checker internals around TypeCore, binder-aware unification, generic inference, static interface validation, provenance substitution, and shared call-resolution facts. - Hardens direct emitters and native artifacts through MIR verifier contracts, direct specialization metadata, target buildability checks, and shared x64, AArch64, ELF, Mach-O, and COFF emission helpers. - Adds clearer direct backend selection, target readiness, and buildability reporting so command JSON and failed native builds expose deterministic blocker facts. - Removes stale wasm, compiler-zero, and superseded parser surfaces while refreshing public docs, README guidance, and zerolang branding around the current system. - Strengthens compiler structure guardrails, metrics budgets, TypeScript-based repo scripts, docs build infrastructure, CI workspace commands, and eval harness isolation. - Renames bundled version-matched skills to the current flat skill names while keeping `zero skills` discovery focused on the native compiler. ### Contributors - @ctate ## 0.1.3 - Adds hosted HTTP client runtime support, including runtime packaging fixes, JSON byte helpers for wasm, HTTP final-header parsing fixes, and direct array span lowering repairs. - Parses `use` declarations into syntax graph facts and reports import diagnostics, fix plans, and graph edges against the specific import source ranges. - Adds structured backend blocker and target-readiness facts to command JSON so checks, build previews, and direct backend failures explain unsupported targets more deterministically. - Expands agent-facing diagnostics with BOR001 borrow trace facts, target-neutral CGEN004 wording, and NAM004 generic type-name shadowing rejection. - Hardens native compiler allocation paths across shared buffers, parser, checker, IR lowering, emitters, source handling, targets, and driver state for deterministic allocation failures. - Updates the public site and docs with current guidance, docs chat rate limiting, and pnpm-based repository workflows. - Restores native versioned skill guidance, keeps the repo wrapper on the native compiler, and removes the legacy `zero skills path` command. ### Contributors - @ctate - @PeterXMR - @h4ckf0r0day ## 0.1.2 - Rebuilds borrow provenance tracking across references, fields, subpaths, assignments, control-flow joins, receiver side effects, generic methods, return summaries, and unreachable paths. - Tightens borrow conflict checking by deriving conflicts from provenance and comparing concrete places, with additional conformance coverage for provenance joins and edge cases. - Fixes checker regressions around borrow origins, reassignment, aggregate values, explicit reference fields, unknown identifiers, and fallibility propagation through wrappers. - Fixes dynamic CLI strings and Darwin executable UUID emission. - Adds Apache-2.0 licensing and lockfile license metadata. - Updates the public site with an install toggle, GitHub star count, and a mobile header Docs link. ### Contributors - @ctate - @badlogic - @chenrui333 - @heylakatos - @onevcat ## 0.1.1 - Adds the public installer at `https://zerolang.ai/install.sh`, with platform selection, GitHub release downloads, checksum verification, and `$HOME/.zero/bin/zero` installation. - Adds `zero run` for the everyday edit loop: build a host executable, run it, pass program arguments after `--`, forward stdout/stderr, and return the program exit status. - Updates README, homepage, getting started, install, and CLI docs around the curl install path, copyable commands, and `zero run`. - Reworks public docs to be more scannable and current, including stronger language, diagnostics, testing, target, package, optimization, and standard library references. - Removes placeholder module docs that described surfaces not ready for users and adds current module docs for `std.crypto`, `std.http`, and `std.net`. - Adds version-matched agent guidance through `zero skills`, including focused workflows for Zero syntax, diagnostics, builds, packages, standard library use, testing, and agent edit loops. - Keeps the installable Zero skill as a thin bootstrap so external skill managers discover one Zero skill while the compiler serves the richer guidance for the installed version. - Updates the `zero skills` CLI contract to serve bundled flat skill data while preserving list, get, path, and JSON workflows. ### Contributors - @ctate - @mvanhorn ## 0.1.0 - Initial public release of Zero as the programming language for agents. - Includes the native compiler, examples, documentation site, and validation fixtures. - Supported workflows use direct Zero emitters for the documented examples and targets.
