Since it seems it is a subject of concern for some people lately, I thought I'd post a few useful links here to help people monitor development.
But first, an introduction: WDLXTV development is done by a group of people (usually identified by an orange name on these forums). When we fix/add something, we post it on a server that contains what is called a code repository. That server (referred to as SVN server, as it runs the SubVersioN software) contains the current snapshot of work-in-progress.
One requirement for us devs when we commit code to it is to provide a description of what the changes are for. Those comments can easily be viewed, giving you a direct view into active (i.e. finished and working) development.
The complete list of SVN repositories:
http://svn.wdlxtv.com/?
To view the changes related to WDLXTV Live specifically:
http://svn.wdlxtv.com/log.php?repname=wdlxtv-live&path=%2Ftrunk%2F&isdir=1&
To view the changes related to UMSP:
http://svn.wdlxtv.com/log.php?repname=UMSP&path=%2F&isdir=1&
To view the changes related to WDTVExt plugins:
http://svn.wdlxtv.com/listing.php?repname=wdtvext-plugins
WDTVExt development itself doesn't appear on the SVN as it's done by a programmer not directly part of the WDLXTV development - his work gets added by b-rad/recliq when it's done.
To look further back in time, change the number of entries shown on the left side (it defaults to the 40 most recent entries max).
In general, we post only finished stuff there (or at least stuff in a usable state, or in need for wider testing). That's why you don't see there anything related to my recent work (last week) on Samba 3.5.1, for example. We occasionally experiment with code and features, and end up scrapping them because they don't work as expected, or cause other issues that aren't worth it. But it shows you how work is progressing in a concrete sense.
WDLXTV Live is now at revision 522 on the SVN (at the time of this post). 0.4.3.1 was released based on revision 395. That means no less than 127 changes were committed to the SVN since then specific to WDLXTV.
More technically-inclined users can run a snapshot of WDLXTV taken from the SVN. Details are here:
