FYI Spring4D 2.0 release candidate 2 is available.
https://bitbucket.org/sglienke/spring4d/src/master/
I’m using it in 2 large projects that use the collections and the DI container and it’s been very reliable (I’ve been using the alpha/beta/rc’s for a while now). Stefan’s employer is also using in production so expect it to be very stable.
To get it, checkout the develop branch.
