====== Version 4 ======
Synchronet version 4 was conceptual future version (after v3.x) that "fixed all the things" in one huge upgrade:

The changes originally planned for a version 4:
  * Replace most of the proprietary binary file formats (''*.cnf'', ''*.dab'') with text, likely [[:config:INI Files]] format [**done**]
  * Overhaul the file database to support modern files (long filenames, sizes > 4GB, etc.) [**done**] and other enhancements (discussions, torrents)
  * Replace proprietary fixed-length text data files (''*.dat''), likely with fixed-length record, variable-length field tab/NL-delimited text files [**done**]
  * Replace many of the native utilities (e.g. [[util:addfiles]]) with [[util:JSexec]] scripts [**done**]
  * Eliminate sub-board "ptridx" concept (cause of bugs when copy/pasting subs in [[util:SCFG]] and other issues [**done**]
  * Expand the maximum length of many of the limited-length fields (e.g. passwords, internal codes) [**done**]
  * Replace hard-coded msg area and file area functions (e.g. reading msgs, file listings, etc.) with [[:module:]]s
  * Filter file (e.g. ''*.can'', ''twitlist.cfg'') overhaul, adding expiration dates, focused areas of filtering, etc. [**done**]
  * FidoNet netmail stored in ''[[dir:data]]/mail'' database [**done**]

... and probably some other stuff from [[http://cvs.synchro.net/todolist.ssjs|this list]].


Rather than a massive version 4 that changed tons of things at once, we've been rolling in progressive enhancements into version 3.x, more or less one feature at a time per release. We will likely continue to do this until there is some massive change that makes virtually all existing Synchronet-related things incompatible with it. None of the todo items in the above bullet list meet that criteria. So, don't be expecting a version 4 any time soon.
