v21.2.1

Bug Fixes
component-loader: Fixed a visual flash where popover content briefly appeared at the trigger element's location before being positioned correctly. This affected popovers using popoverContext in zoneless mode. (#6817)
typeahead: Fixed several accessibility issues (#6791):
Changed the container role from listbox to combobox for correct ARIA semantics
Switched from aria-owns to aria-controls per ARIA spec
Fixed activeChangeEvent not firing when the active item changed via keyboard navigation; it now consistently emits (emitting an empty string instead of undefined when cleared)
Refactoring / Internals
component-loader: Replaced the deprecated ComponentFactoryResolver API (removed in Angular 17+) with the modern createComponent() + EnvironmentInjector API. Affects dynamic overlay rendering for Modal, Tooltip, Popover, Typeahead, Dropdown, and Datepicker. (#6813)
animations: Removed the @angular/animations peer dependency. Collapse, Dropdown, Datepicker, and Typeahead now use pure CSS transitions with a shared animateExpand / onTransitionFinished utility (exported from ngx-bootstrap/utils). This reduces bundle size and removes the requirement to import BrowserAnimationsModule. Existing consumers do not need any code changes. (#6812)

v21.2.0

BREAKING CHANGES

• zoneless: Completed migration to Angular's zoneless change detection. zone.js is no longer required and has been removed from dependencies.
• zoneless: All components now use ChangeDetectionStrategy.OnPush. Applications must use provideZonelessChangeDetection() in their bootstrap configuration.
• inputs: All @Input() decorators have been replaced with the input() signal function API. Programmatic access to component inputs now requires signal read syntax (e.g., component.myInput() instead of component.myInput).
• outputs: All @Output() decorators have been replaced with the output() function API. Output emissions continue to use .emit().
• services: Removed NgZone dependency from carousel, component-loader, positioning service, and focus-trap. Replaced NgZone.onStable with afterRenderEffect().
• modules: Removed deprecated forRoot() static method from all 17 module classes (AccordionModule, AlertModule, ButtonsModule, CarouselModule, CollapseModule, BsDatepickerModule, BsDropdownModule, FocusTrapModule, PaginationModule, PopoverModule, ProgressbarModule, RatingModule, SortableModule, TabsModule, TimepickerModule, TooltipModule, TypeaheadModule). These methods were no-ops returning empty providers and were deprecated since v18. Simply use the module directly in imports (e.g., TooltipModule instead of TooltipModule.forRoot()).
• schematics: ng add schematics now generate module imports without .forRoot().
