    🔒 Security fix

    🚀 This release fixes a security issue, reported at https://www.cvedetails.com/cve/CVE-2018-10945/

    🖐 ( Fix body length calculation in mg_handle_cgi)

    🔄 Change List:

    Add mg_url_encode_opt() - a parametrized version of mg_url_encode()

    Add MG_HIDE_SERVER_INFO

    mg_file_upload_handler: Support multiple files

    ➕ Add host name verification for OpenSSL

    ➕ Add mg_strstrip: trims whitespace at both ends of a string

    🛠 Fix http pipelining

    🛠 Fix buffer size passed to inet_ntop()

    🛠 Fix an edge case in multipart HTTP upload parsing

    Fix mg_http_parse_header (treat ; as a delimiter)

    mg_lwip: Fix race during clean connection teardown

    Fix a bug in mg_mgr_init_opt with opts.num_ifaces

    Fix build with CS_ENABLE_STDIO=0

    🛠 Fix warnings on newer versions of GCC

    🖐 Fix body length calculation in mg_handle_cgi

    Don't touch send_mbuf when sending MQTT messages

  • v6.11 Changes

    February 08, 2018
    • 🛠 Fix socket leak when there are too many open file descriptors
    • 🛠 Fix publish-subscribe example
    • 📜 Fix mg_parse_multipart in case of malformed request
    • Websocket: Respond to Ping with Pong
    • Websocket: Properly close a connection with Close frame (in response to a client's close and when protocol failure is detected)
    • 👍 Websocket: Fix support of fragmented messages
    • 👍 Websocket: Add support for control frames interjected in the middle of a fragmented message
    • Digest authentication: Fix nonce validity check (expired nonce or nonce from the future did not cause the the check to fail)
    • Digest authentication: Fix nonce request value; it worked before because nonce validity check was broken as well
    • Digest authentication: Add nonce argument to mg_http_create_digest_auth_header(): clients should use the value received from the server's authentication request.
    • Fail if passed a NULL handler to mg_bind or mg_bind_opt.
    • ✅ Publish sources and tests
    • ✂ Remove tunneling functionality which was used by nobody
    • ➕ Add UDP client example
    • Don't use user_data in mqtt server
    • Deprecate mg_http_parse_header() and implement mg_http_parse_header2() instead, which allocates a new buffer if the client-provided one is not large enough (similarly to asprintf).
    • 🛠 Fix limitations of header value lengths, e.g. when parsing authentication headers such as nonce, etc.

  • v6.10 Changes

    October 31, 2017

    API changes

    • 👍 SOCKS5 client and server support
    • Timer value is no longer cleared after MG_EV_TIMER event if it was not changed. User's handler must set it to 0 explicitly to avoid repeated invocation.

    🛠 FIxes

    • SSL/TLS listener fix for TI SimpleLink networking interface
    • 🚧 Double-counting of recved bytes in LWIP interface caused issues
    • 📜 MQTT SUBSCRIBE command parsing in the broker code could cause crashes
    • 🛠 FIxed CGI script connection lifetime management

  • v6.9 Changes

    September 13, 2017
