+** IMPORTANT CHANGE **
+
+- change: `insecure_basic_auth` now defaults to `true` instead of `false`
+
+  This restores backward compatibility with pre-1.24.0 behavior where basic auth 
+  was allowed over HTTP connections. If you need strict HTTPS-only basic auth:
+  - Set globally: `application:set_env(hackney, insecure_basic_auth, false)`
+  - Or per-request: `{insecure_basic_auth, false}` in options

-** Breaking Change **
-
-The new `insecure_basic_auth` application variable defaults to `false` for security.
-If your application relies on insecure basic auth over HTTP, you must explicitly set 
-`application:set_env(hackney, insecure_basic_auth, true)` to maintain previous behavior.
