 ## Highlights
 
-### WinGet (Windows)
+### Validate claims (opt-in)
 
-jwtd is now installable with the built-in Windows Package Manager:
+jwtd can now enforce claim validity, not just display it. Pass `--verify-claims` to check the temporal claims and exit nonzero when a token is expired or not yet valid:
 
 ```
-winget install WebCodr.jwtd
+jwtd --verify-claims <token>
 ```
 
-The manifest installs the same signed release binary as every other channel, packaged as a portable zip whose hashes are taken from the release's signed `checksums.txt`. Windows releases now ship an additional `.zip` archive alongside the existing `.tar.gz`; its `jwtd.exe` is byte-for-byte the same binary. Scoop, Homebrew, AUR, Fedora COPR, and Nix are unchanged.
+Add `--aud` and/or `--iss` to additionally require a specific audience or issuer (either flag implies validation):
+
+```
+jwtd --aud my-api --iss https://issuer.example <token>
+```
+
+The verdict prints as a `Claims: VALID` / `Claims: INVALID` section and is reported as `claimsValid` under `--json`. Claim validation is independent of signature verification: it runs with or without `--key`, and when both are used the command exits nonzero if either check fails. A token with no `exp` is not treated as expired, and the default behavior is unchanged — a bare decode still never fails on expiry.
+
+### Relative timestamps
+
+Decoded `exp`, `nbf`, and `iat` claims now show how long until — or since — they matter: `expires in 14m`, `expired 2h ago`, `not yet valid, in 5m`. This is display-only and never affects verification or the exit code, and the `--json` output keeps the raw numeric claim values.
+
+### Fixes
+
+- Reading a token from a closed or detached stdin no longer panics; jwtd falls back to the interactive prompt.
