+## Changelog
+
+### v0.11 (2024-11-20)
+
+This release was published to disable insecure requests.
+
+❌ Removed: curl default parameter `-k` (it disables ssl verification)
+⚠️ Deprecated: The new filename is `http.class.sh`. When using `rest-api-client.sh` you get a deprecated warning on STDERR
+🔷 Added: function `http.setInsecure` - set "1" to enable `-k` again; use no parameter to disable
+🔷 Added: function `http.setCA "<file>"` to define a custom ca file (results in `--cacert <file>`)
+🔷 Added: function `http.addCurlparam "<parameter>"` to add any missing curl parameter
