shiny 1.6.4

Bug fixes

• Fixed a path-traversal vulnerability in bookmark restore (CWE-22). Introduced in 1.4.0. Reported by @0xRenSec.
• When bookmarked state cannot be restored, the notification shown in the client is now a generic message. The reason is logged server-side as a warning on the shiny.bookmark._restore_state logger, so app authors can still see it. (1d8ecb4)
