[BRLTTY] stupid svn question

[mrkiko]

I'm not very experienced with svn, but I like to use the svn last version of 
brltty to find out possible bug for notice them and so help all the people 
develping this project that save my life, seriously! (THANK YOU!!!) I'm also 
(i'm attempting to be) a responsible user and, i'm interested in developing 
techniques also so I read all my changelogs. How can i see changes made in the 
last revision? I know that svn can display changed files but ... are commented 
changes existing? Or must I search them with a compare utility ? Thank.
