   summary: A synchronous HTTP client for Mojo.
   description: |
-    Send HTTP/1.1 requests with JSON, forms, authentication, cookies,
-    connection reuse, streaming, timeouts, and TLS verification.
+    Send HTTP/1.1 and opt-in HTTP/2 requests with JSON, multipart and file
+    uploads, HTTP/HTTPS proxies, connection pool limits, hooks, injectable
+    transports, response iterators, and verified TLS.
     Includes the native shared library and the CPU source modules from
     ehsanmok/json 0.4.1. The native transport loads automatically from
     the active environment; consumers need no extra linker flags.
