In order to get the next curl release done, we’re entering feature freeze on Sunday August 10 (at 00:00 UTC to make it specific).
Starting then, we add no new features for the upcoming two weeks but we only fix bugs. At the end of the two week period, or possibly before that if all looks well, we release 7.19.0.
The work on CURLOPT_POSTREDIR and the “Limiting IP addresses” work can of course continue but if we don’t have working patches for them very quickly, they’ll have to wait for next release.
