You might have already noticed, but I thought I'd write an entry on this blog on this topic: the wait is over I have released syslog-ng 2.0.0. It took a bit longer than I have anticipated, I needed to prepare 4 rc releases, as each had some bug here or there and I really wanted to release a stable 2.0.0
I hopefully succeeded, no breakage reported so far. 2.0.0 was released last saturday, but the announcement went out only on Friday.
Some rarely used functionality is still missing though (a prominent example is spoof_source), and I already committed the remove_if_older() option after the release of 2.0.0. I'm going to concentrate on filling the missing bits.
I'll try to avoid committing to 1.6.x, migrating to 2.0.x is strongly recommended.
