 ## Unreleased
 
-- Add workflow file runner for `.lobster`/YAML/JSON workflows with args, env, conditions, and approval gates.
-- Add compact workflow resume tokens backed by Lobster state storage.
-- Add `exec --stdin raw|json|jsonl` to pipe workflow output into subprocess stdin.
-- Add `approve --preview-from-stdin --limit N` for approval previews without extra glue.
-- Add `openclaw.invoke --each` to map pipeline input items into tool calls. (`clawd.invoke` remains supported as an alias.)
-- Extend CLI to run workflow files with `lobster run <file>` or `--file` + `--args-json`.
+## 2026.4.6
+
+- Add workflow file support for `.lobster`/YAML/JSON files, including args, env, native pipeline steps, and shell-safe `LOBSTER_ARG_*` workflow args.
+- Export the embeddable core runtime via `@clawdbot/lobster/core` so Lobster can be loaded in-process by OpenClaw and other hosts.
+- Add compact state-backed workflow and pipeline resume tokens, plus hardened approval ID handling and safer resume validation.
+- Add structured input pauses with `ask`, workflow `input`, `needs_input`, and `lobster resume --response-json '{...}'`.
+- Add richer workflow condition expressions with `!`, `==`, `!=`, `&&`, `||`, and parentheses.
+- Add generic `llm.invoke` adapters, `openclaw.invoke --each`, and keep `clawd.invoke` as a supported alias.
+- Add `exec --stdin raw|json|jsonl`, `approve --preview-from-stdin --limit N`, and extensive dry-run hardening for workflow templates and shell-variable preservation.
+- Improve Windows compatibility for CLI startup/build scripts and fix quoted-argument parser edge cases.
