I've been seeding 3 at a time from a queue of torrents. I've found that v. 2.30b1 does not always stop seeding at the seeding limit ratio set in the advanced tab of Inspector. On at least 2 occasions I've had it run right past the limit and continue seeding.
This version of Trans will also sometimes load all the torrents in the "waiting" queue when the active seeding torrents fall below 3 - but this is nothing new. I *think* it's related to whether the torrents being loaded are higher in the queue than a currently seeding queue. (i.e. when I go back to older torrents to do additional seeding.)
I'm writing in this forum section to see whether anyone else can confirm the above.
