-Latest version of Echo supports last four Go major [releases](https://go.dev/doc/devel/release) and might work with older versions.
+Echo v4.16.1 requires Go 1.26 or later so it can use patched `golang.org/x/` dependencies. Use a supported, patched Go toolchain when building applications.
+
+### Security defaults in v4.16.1
+
+`BodyDump` captures at most 5 MiB of the request and 5 MiB of the response by default. The application and client still receive the complete bodies. Configure `BodyDumpConfig.MaxRequestBytes` and `MaxResponseBytes` to change the capture limits; `-1` disables a limit.
+
+`Decompress` limits decompressed request bodies to 100 MiB by default. Reading beyond the limit returns HTTP 413, including through JSON and XML binding. Configure `DecompressConfig.MaxDecompressedSize` to change the limit; `-1` disables it. Apply any smaller application body limit after decompression.
+
+The proxy now validates WebSocket upgrade responses, closes both WebSocket connections when either side disconnects, and removes incoming `Forwarded` headers. Backends should use the proxy's validated forwarding headers and enforce their own authorization.
