Elixir Luv V 0.3.0

Changelog

0.3.0 - 2026-05-01

• Added elv repl --backend daemon for authoritative source-level execution through a long-running V daemon, with replay degradation diagnostics.
• Added front fast-path freezing diagnostics so :doctor shows front_fast, frozen reason, pending sync count, and native fallback count.
• Kept the Engine-internal fast evaluator synchronized with authoritative session state while freezing only the speculative CLI front path after native fallback.
• Added semicolon sequence handling for forms like mut counter := 1; counter += 2; counter across replay, hot-load rendering, and daemon execution.
• Added replay fallback synchronization after daemon eval failure so successful daemon history is replayed before fallback continues.
• Added replay-vs-daemon fallback benchmarking with median/p95 output and V compile-bound labeling.

0.2.0 - 2026-04-30

• Started the v0.2 runtime foundation: ELV now boots as an OTP application with a dynamic session supervisor.
• Moved the replay evaluator behind an execution backend behaviour so future live/plugin/worker backends can share the same session surface.
• Added a SessionServer for runtime metadata, history ownership, restart handling, evaluation timing, timeout counts, and crash accounting.
• Expanded session diagnostics with backend, temp root, snapshot status, generation, form counts, and compile/run timing details.
• Added source-level checkpoint files with deterministic/side-effecting form tracking.
• Added :recover for latest-checkpoint replay and :crashes for visible crash/timeout counters.
• Added a supervised disposable worker backend, exposed with elv repl --backend worker.
• Added worker crash replacement tests so the session process survives a crashed execution worker.
• Started the v0.3 editor layer with an EditorServer for multiline input buffering, submitted-form history, and :search.
• Added a shared form classifier and BuildServer foundation for generated-source caching and future live/plugin backends.
• Added optional LSP client plumbing with JSON-RPC framing plus :diagnostics and :complete hooks for elv repl --lsp.
• Added explicit checkpoint replay plans so recovery reports replayed and skipped side-effecting forms.
• Added automatic crash recovery from checkpoints and worker recycle policy support with replay restore.
• Added real VDaemon-backed live and plugin backend entry points with generation-specific artifacts, load/unload tracking, recycle policy, capability diagnostics, and replay fallback.
• Added :capabilities and :snapshots commands for inspecting backend support and recovery state.

0.1.0 - 2026-04-30

Initial public release.

• Julia-style REPL shell for V: ?, ;, ], @time, :load, :reset, :history.

• Persistent V path setup with elv config set v.path PATH and elv v use PATH.
• Managed V bootstrap with elv v install, backed by the official vlang/v source repository.
• Diagnostic commands: elv doctor, elv locate, elv v path, and :doctor.
• Universal release layout with POSIX and Windows launchers.
