Upgrading from v5 to v6

v6 is a new engine: native tagged templates (minifier-proof), fine-grained signals, contracts, and complete destroy semantics. The shape stays recognizably lemonade (a function, states, one template), and every v5 pattern has a precise new home. Previous versions remain documented under /docs/v5.

The map

v5	v6
`return render => render`…“	`return html`…“ (tag renamed, no wrapper)
`lemonade.render(Comp, root)`	`mount(Comp, root)`
`this.prop` / `{{self.prop}}`	`const prop = state(…)` + `${prop}`
`onload(fn)` / `:ready`	`onMount(fn)` (return a cleanup) / `ref="${fn}"`
`self.onchange(prop, o, n)`	`state(v, (val, old) => …)` per state
`:loop="self.rows"`	`${() => rows.value.map(r => html`…`)}`
`:render="${cond}"`	`${() => cond.value && html`…`}`
`:bind="self.name"`	`bind="${name}"` (elements) / `bind()` tool (components)
`lemonade.set/get/dispatch` (Sugar)	`store()` + actions, or `expose`/`use()`
`lemonade.set(k, fn, true)` persistence	`store(initial, 'storage-key')`
`setComponents({ Card })` + `<Card/>`	same, or embed by value: `<${Card} />`
`lm-path` / `setPath` forms	`form()` with `$get`/`$set`
HTML strings in slots	escaped by default; `unsafe(html)` for trusted markup
`self.refresh('prop')` / `refresh()`	`state.touch()` after in-place mutation
`createWebComponent(name, fn)`	same, or contract-driven: `createWebComponent(Comp)`
per-plugin `react.js` wrappers	one generic `adaptReact(Comp)`

What was removed on purpose

The mutable this/self bag, {{…}} token expressions, inline-string event handlers and the Function() evaluator (CSP), attribute auto-casting, and the view.toString() template recovery. Each removal closes a class of silent failures; the contracts layer restores typed coercion and interface introspection on declared terms.

What is new with no v5 equivalent

Contracts (component, contract, verify), touch()/batch() for big-data mutation, subscribe()/peek() interop, the test harness, stable error codes, and dev/production builds with build-time dead-code elimination.
