Mongoose 6.3

This release concerns commercial users only. From this release on, there are no separation for lite/standard/premium version.

Technical changes (bugfixes, new features) are scheduled for the next 6.4 release in mid-April.

6.2

What's new in the Mongoose Library

• WebDAV support improvements. With a just a couple of lines of code your web server is ready to serve WebDAV and can be mounted as a network drive in very different clients, like Finder on MacOS, Explorer on Windows and Nemo, Nautilus (and others) on Linux. Just add dav_document_root to initialization parameters and your are ready to go. See simplest_web_server example.
• Timer support. Mongoose 6.2 introduces new event - MG_EV_TIMER. With event and new API function mg_set_timer things like connection timeout (and a lot of another timeout-related features) can be easily implemented. Call mg_set_timer(my_connection, time(NULL) + N) and my_connection will receive MG_EV_TIMER once N seconds is elapsed. Sub-second precision is also supported, and the mg_time function which returns current time as a fraction floating point value has been added.
  See API documentation for more details.

Other changes:

• MG_EV_CLOSE is now always delivered before connection is destroyed. This should simplify cleanup.
• New API function: mg_url_decode to decode URL-encoded string.
• g++ and Microsoft Visual Studio support was improved

Mongoose 6.1

What's new in the Mongoose Library

• Native support for PicoTCP embedded TCP/IP stack
• Native support for LWIP embedded TCP/IP stack
• Native support for ESP8266 SDK (see example)
• Native support for CC3200 FreeRTOS SDK
• Added ability to specify extra headers for mg_serve_http() - that implements e.g. CORS on server side
• Added ability for automatic port-based redirects, for HTTP->HTTPS redirects
• Multiple bigfixes

Mongoose editions

For commercial use, Mongoose is available in three editions:

• Mongoose Lite: Cross platform integration, SSL/TLS, HTTP support
• Mongoose: Mongoose Lite + HTTP CGI, HTTP SSI, HTTP Digest Auth, WebSocket support
• Mongoose Premium: Mongoose + Plain TCP, UDP, JSON-RPC, MQTT, DNS, CoAP support

Mongoose 6.0

Overview

This is a major release of Mongoose. It brings new capabilities, making Mongoose a multi-protocol network library rather then only HTTP/Websocket. That means more flexible and rich API. New Mongoose API is not backward-compatible with pre-6.0 versions.

What's New

• Support for plain TCP, plain UDP
• Support for Websocket client
• JSON-RPC client, JSON-RPC server
• MQTT client, MQTT broker
• CoAP client, CoAP server
• DNS client, DNS server, async DNS resolver
• SSL layer improvements, including modern cryptography support
• New API

Architecture notes

Pre-6.0 Mongoose was hiding the implementation from the user. Like, internal connection structures, sockets, etc. Mongoose 6.0 opens everything to the user. This has it's pro and cons. The decision to open the guts of the library is to provide power users to take full control over the IO engine. Basic use cases are well covered by the example that are provided in abundance.

Mongoose Editions

Mongoose 5.3

Changes in Libmongoose library:

• Moved to the evented API. Updated API documentation is at
  http://cesanta.com/docs/Embed.shtml
  http://cesanta.com/docs/API.shtml
• Added MG_LUA event for exporting custom variables to the Lua environment

Changes in pre-compiled binaries:

  Check them out at http://cesanta.com/products.shtml
• Added Lua Server Pages support to the free version, quick intro is at
  http://cesanta.com/docs/Lua.shtml
• Added quick "Set shared directory" menu item to set document_root
• Added SSI support to the Pro version
• Removed SSL support from the Pro version

Mongoose 5.2

• Windows binary made fully UNICODE aware. In previous versions,
  the presence of non-ASCII chars in document root, CGI script name,
  or directory name might have broken Mongoose as stand-alone
  or as Windows service. Now Mongoose works with non-ASCII paths properly.
  Internally, Mongoose uses UTF8 encoding. When making WinAPI calls,
  mongoose converts UTF8 strings to wide chars and calls UNICODE API.
• Enhanced authorization API by providing mg_set_auth_handler() and
  mg_authorize_digest()
• Removed mg_add_uri_handler(), added mg_set_request_handler().
  There is only oneURI handler that handles all requests, just like in 4.x.
  The reason for this change is to provide an ability to catch all URIs,
  and at the same time signal Mongoose to continue handling specific URIs.
• Added mg_parse_multipart() API for file uploads.
  Note that the restriction on uploading huge files still exists,
  and will be eliminated in the next release.
• Allowing mongoose to bind to port 0, in which case it'll bind to any
  random unused port.
• Moved idle_timeout_ms run-time option to compile-time flag
• Added asynchronous HTTP client, not documented yet. Documentation and
  examples are coming in the next couple of weeks. Async Websocket client
  is scheduled for the next release. See usage examples at unit_test.c
• Windows and MacOS pre-built binaries are now split to free and paid ones,
  paid binaries include CGI, SSL, Lua, Sqlite, support and updates.
  Linux pre-built binary includes all functionality and is free, and will
  continue to be free. Source code for Windows and MacOS GUI is closed.
  Disclaimer: source code for the command line stand-alone server,
  as well as Mongoose library itself, will never be closed.
• Multiple bug fixes and minor enhancements

Mongoose 5.1

• CGI-related bugs where fixed, primarily for Windows platform
• Bugs on Windows related to UNICODE support were fixed
• Added a feature to support "error pages" through redirect.
  Done using -url_redirects option, details are on
