    👌 Improvements

    • 👍 [jss] Add support for Typed CSSOM values (#882)

    • 📦 [all] Add TypeScript definitions to all packages (#889)

    💥 Breaking changes

    • 📦 [jss] Observables, function values and rules are now standalone packages, not part of the core. They are still part of the default preset though.
    • ⚡️ [jss] Function values, rules and observables apply plugins by default now, which means they can support all plugin defined syntaxes, but they are also slower by default. To speed them up use sheet.update(data, {process: false}) for fn values/rules and jss.use(pluginObservable({process: false})) when setting up observables plugin. (#682)
    • 0️⃣ [jss] Rule @keyframes has now scoped name by default, which means that you can access it using $ref from the same sheet and generate global one as before using @global rule (#346).
    • 👍 [jss] Add scoped keyframes support (#346)
    • [jss|react-jss] Options createGenerateClassName and generateClassName are renamed to createGenerateId and generateId because the same function is now used to scope @keyframes rules.
    • 👍 [react-jss] Drop support for older React versions, require v16.3 or higher (#868, #851)
