OpenJS Foundation (先前的 jQuery Foundation) 宣佈 jQuery UI 與 jQuery Mobile 進入維護模式：「jQuery maintainers update and transition jQuery UI as part of overall modernization efforts」、「jQuery maintainers continue modernization initiative with deprecation of jQuery Mobile」。
jQuery UI is in maintenance-only mode. Users should not expect any new releases, though patches may be issued to resolve critical security, interoperability, or regression bugs.
The team announced that the cross-platform jQuery Mobile project under its umbrella is fully deprecated as of October 7, 2021.
應該就是沒有足夠的動能繼續開發了，維持個窗口在有 security issue 時處理...
