• breaking: Require Sync for all handlers and services added to Router and MethodRouter (#2473)
• breaking: The tuple and tuple_struct Path extractor deserializers now check that the number of parameters matches the tuple length exactly (#2931)
• breaking: Upgrade matchit to 0.8, changing the path parameter syntax from /:single and /*many to /{single} and /{*many}; the old syntax produces a panic to avoid silent change in behavior (#2645)
• change: Update minimum rust version to 1.75 (#2943)
