-# Mongoose Web Server
+# <img src="http://cesanta.com/images/mongoose_logo.png" width="64" height="64"> Mongoose Web Server
+
+Mongoose is the most easy to use web server on the planet. A web server of choice for Web developers (PHP, Ruby, Python, etc) and Web designers.
+
+Mongoose is built on top of Libmongoose embedded library, which can turn
+anything into a web server in 5 minutes worth of effort and few lines of code.
+Libmongoose is used to serve Web GUI on embedded devices, implement RESTful
+services, RPC frameworks (e.g. JSON-RPC), handle telemetry data exchange, and
+perform many other tasks in various different industries including aerospace,
+manufacturing, finance, research, automotive, gaming, IT.
+
 
-Mongoose is easy to use, powerful, embeddable web server.

+
+## Release 5.3, March 10 2014
+
+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
+   *  Added virtual hosts capability, see `url_rewrites` option description at
+       http://cesanta.com/docs/Options.shtml
+   *  Added mjpg serving example
+   *  Cleaned up and documented HTTP client API, with unit tests
+   *  Added `mg_wakeup_server()` to awaken `mg_poll_server()`
+      from another thread
+   *  Moved Mongoose IO core to [https://github.com/cesanta/net_skeleton](Net Skeleton)
+   *  Added connection hexdump functionality for developers
+   *  Bug fixes
+
+Changes in pre-compiled binaries:
+
+   *  New awesome Mongoose logos by our designer Katrin - thanks Katrin!
+        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
+
+## Release 5.2, Feb 1 2014
+
+   *  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
+
+## Release 5.1, Jan 10 2014
+
+   *  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
+      http://cesanta.com/docs/Options.shtml
+
+## Release 5.0, Jan 6 2014
+
+   *  Internal core has been changed from blocking, thread-per-connection to
+      non-blocking, asynchronous, one thread for all.
+   *  API modification for server creation and response creation. That allowed
+     keep-alive support for dynamic requests, boosting the embedded performance
+     to 100+ thousands requests per second on a single core
+     (as measured on my development MacBook laptop)
+   * Unified handling of POST requests and Websocket requests by putting a
+    payload into `conn->content`, `conn->content_len` attributes.
+    That simplified user code and eliminated the need of `mg_read()`,
+    since mongoose buffers all data prior to calling the callback
+   * keep-alive support is the default
+   * Dropped SSI support and throttling support
+   *  Several configuraition parameters are gone:
+    *  `cgi_environment` (replaced with MONGOOSE_CGI),
+    *  `protect_uri` (not useful)
+    *  `ssi_pattern` (SSI support is gone)
+    *  `throttle` (throttling support is gone)
+    *  `error_log_file` (not used)
+    *   `enable_keep_alive` (enabled by default)
+    *   `listening_ports` (renamed to listening_port)
+    *   `num_threads` (core has changed to single thread)
+    *   `put_delete_auth_file` (renamed to dav_auth_file)
+    *   `authentication_domain` (renamed to auth_domain)
+   * Due to the async, non-blocking nature of the core, few restrictions
+      are now in place:
+    * user callbacks must not block
+    * POST and Websocket data are now buffered, and cannot be huge
+   * mongoose is now capable on listening on only one port
+
+## Release 4.1, Oct 2013
+## Release 4.0, Oct 2013
+## Release 3.8, Sep 2013
+
+## Release 3.7, Feb 2 2013
+
+  *  Added "redirect to SSL port" functionality, e.g. if you specify
+      `-listening_ports 8080r,8043s`
+      then all requests to HTTP port 8080 will be redirected to HTTPS port 8043
+  *  Added `mg_download()` API, an HTTP client interface!
+  *  Lua server pages now must output HTTP headers -- full control for Lua
+  *  Added pre-built binary for MacOS, with initial GUI support
+  *  API change: got rid of events, moved to struct `mg_callbacks`
+  *  Bugfixes, thanks to contributors
+
+
+## Release 3.7, Jan 18 2013
+  *  Fixed source code archive (main.c was missing)
+  *  Extended Windows GUI functionality:
+   * Added "Start browser" systray popup menu item
+   *  Enhanced configuration editor
+  *  Renamed config options:
+   * `put_delete_passwords_file` -> `put_delete_auth_file`
+   * `global_passwords_file` -> `global_auth_file`
+  *  `select()` changed to `poll()`, to avoid big file descriptor
+  `FD_SET` problem on UNIX
+  *  Couple of bugfixes, thanks to contributors
