I and several testers are still at work on the new version. I won't pretend to predict its release this time, but it is mostly complete and solid. I'm sorry I haven't had as much time to finalize it as I'd like.
I'm still working on the new release. I have several people helping me to test it. We are covering a number of configurations and usage patterns, so hopefully the result will be good for all. I eat my own dog food; I use the development version every day, so you can imagine it is pretty stable.
There is one major refactoring effort before me. I'm still surveying the code for that functionality to ensure that the refactored design is appropriate. Once done, we'll have to test the changes, of course.
I am working on a major new release of p4.el. It is significantly improved in myriad ways, but I'm still working out niggling problems. If you're interested in helping to test the new version, contact me.
This project has languished for a while. There is now a new admin.
