- Bump version in package.json from 0.1.4 to 0.1.5.
- Update peer dependency for @tanstack/react-query to allow version 5.0.0.
- Add @tanstack/react-table and @tanstack/react-virtual as dependencies.
- Update various dependencies to their latest compatible versions.
- Simplify postcss.config.js by removing unnecessary options.
- Clean up rollup.config.js by removing ignored PostCSS warnings.
- Update CheckboxButton component to cast icon as React JSX element.
- Adjust Combobox component's class names for better styling.
- Change DropdownPopup component to use React's namespace import.
- Modify InputOTP component to use 'any' type for OTPInputContext.
- Ensure displayLabel and value in ModelParameters are converted to strings.
- Update MultiSearch component's placeholder to ensure it's a string.
- Cast selectIcon in MultiSelect as React JSX element for consistency.
- Update OGDialogTemplate to cast selectText as React JSX element.
- Initialize animationRef in PixelCard with undefined for clarity.
- Add TypeScript ignore comments in Select and SelectDropDown components for Radix UI type conflicts.
- Ensure title in SelectDropDown is a string and adjust rendering of options.
- Update useLocalize hook to cast options as any for compatibility.
