Incompatibility list

We assume that the name of your executable file is w3mmee.

Incompatibilities against p23-1 or prior

1. Backend mode is abolished.

Incompatibilities against p22 or prior

1. Width of each character on terminal is assumed 0, 1, or 2.
2. When HTTP response code is 301 or 302, w3mmee keeps HTTP method.

Incompatibilities against p21 or prior

1. Inline images are preloaded only when configuration option ``preload_image'' is set to true value.
2. Meaning of onfiguration option ``concurrent'' has changed. I really suggest not to specify this option in your configuration file.

Incompatibilities against p20 or prior

1. Configuration options ``tty_accept_character'' and ``tty_reject_character'' are integrated into ``tty_character_conversion''. Configuration options ``tty_accept_character'', ``tty_reject_character'', and ``tty_ucs_ready'' are abolished.
2. Configuration option ``mailcap'' now requires comma-separated alternating list of the form

   <boolean value to specify posibility that w3mmee is specified in the file>, <file name>, and so on,

   instead of simple list of file names.

Incompatibilities against p19 or prior

1. Default value of configuration option concurrent is now 1.
2. If you are using wheel mouse on XTerm or RXVT, you need to add the lines

   MOUSE-CLICK-4 DOWN 5
   MOUSE-DCLICK-4 DOWN 5
   MOUSE-CLICK-5 UP 5
   MOUSE-DCLICK-5 UP 5
   

   to $HOME/.w3mmee/keymap.
3. Values of User-Agent:, Accept-Charset:, and Accept-Language: are set with configuration option request_header, e.g.

   request_header User-Agent: ...
   request_header Accept-Charset: ...
   request_header Accept-Language: ...
   

   Individual options are all abolished.
