Sorry - I tried look for history/svn changes on the website and none was available.
A website is not relevant for this development process. You can checkout and test the latest changes from the Subversion server.
If downloading a SVN client helps - that is great! Thank you. (I don't use SVN for my own projects since I am just myself and use fpcupdeluxe for installing Lazarus)
Well, fpcupdeluxe uses SVN client! However you don't need fpcupdeluxe for Lazarus trunk. Just do "svn co ..." and "make". Later update with "svn up". Easy.
fpcupdeluxe is for more complex things like cross-compilers and maybe FPC trunk.
Don't turn simple tasks into complex please.
