I totally agree kracker. Is there anywhere that I can see previous release dates of old versions?
I have looked at the ezpublish roadmap and found it useful to a certain degree, but it does not provide the detail that I feel would be necessary to answer the questions I had. I also know that adding expected release dates to ezpublish releases may give false expectations to developers, however if it was clearly indicated that it is only an estimation and the estimations were reviewed regularly. I dont think there would be a problem.
I guess i am still not sure how many releases to expect in a year and i understand it is a hard question to answer. Does anyone know of any records of previous release dates for the ezpublish releases? If anyone knows if this information doesn't exist i'd be happy just to know.
Normal behaviour is one or two major releases a year with several maintence releases in between. Of late its been one'ish... There has been no word on other 3.X releases but i would be surprised if 3.9 doesnt appear.
However, with eZ 4 on the horizon sometime next year its not clear if this pattern will change. And you have to realise that eZ 4 will not be backwards compatible but there will be lots of upgrade solutions to counter this.
I would budget for 3.8 and wait another year before going to 4.
You can check the dates of when the release branches were added to SVN here. http://pubsvn.ez.no/websvn/listing.php?repname=nextgen&path=%2Frelease%2F&rev=0&sc=1
This will at least give you a historical picture of the frequency of releases.
On a practicable point you could allow for 4,6,8 updates and let the client know that additional ones would cost $X per update.
