V2.0.0-alpha.0

Removed

• [Sidebar] Removed the ProSidebarProvider component (deprecated since 1.1)
• Removed the useProSidebar hook (deprecated since 1.1) — use Sidebar props instead
• [Sidebar] Removed the defaultCollapsed prop — use the controlled collapsed prop
• [Sidebar] Removed the breakPoint="always" value — use breakPoint="all"
• [Sidebar] Removed the customBreakPoint prop — pass a custom value to breakPoint instead (e.g. breakPoint="450px")

Changed

• Breaking: React peer dependency is now >=18 (dropped React 16 / 17 support); React 19 is supported
• Runtime dependencies (@emotion, @popperjs, classnames) are now externalized instead of bundled, reducing install size and avoiding duplicate copies
• The package now ships a proper exports map with ESM (dist/index.mjs), CJS (dist/index.js) and a types entry

Added

• [Menu] New popover prop — top-level SubMenus open as floating poppers even when the sidebar is expanded (instead of sliding open inline)
• [Menu] New accordion prop — when set, only one top-level SubMenu can be open at a time. Opening another closes the previously open one
• [SubMenu] New accordion prop — coordinates only the submenu's direct children (per-level scope, independent of any ancestor accordion)
• [SubMenu] Active state now cascades automatically — a SubMenu is marked active whenever any of its descendants is active
• [Sidebar] Pressing Escape now closes the sidebar when open as an overlay (broken + toggled)
• [Sidebar] Focus moves into the sidebar when it opens as an overlay
• [MenuItem] aria-current="page" on active items and aria-disabled on disabled items
• [SubMenu] aria-expanded on the trigger, aria-haspopup="menu" when a collapsed top-level submenu opens as a popup, and aria-disabled on disabled triggers

Fixed

• [Sidebar] Backdrop now uses onKeyDown and activates only on Enter / Space (replacing the deprecated onKeyPress, which fired on any key)
• [SubMenu] Items in a closed submenu are no longer reachable via Tab or exposed to screen readers — the closed submenu content is now marked inert
• [SubMenu] Trigger now has role="button", so its aria-expanded / aria-haspopup state is valid (it previously sat on a roleless <a>)
