How can we tell when the next version of OpenCV (ex. 3.0.1 ??) will be released ?

Good afternoon everybody,

I'm planning on updating my OpenCV installation tutorial video and associated GitHub project, and I'm curious as to when the next version of OpenCV (which I'm supposing will be 3.0.1 but I don't know that for a fact) will be released.

I'm asking this question specifically for information on when the next version will be released, but also generally as I'm interested in the process of how this decision is made.

Before somebody responds with "It's done when it's done", yes, of course I'm aware there is not an official published release date and the next OpenCV version will not & should not be released until it's truly ready.

However, I would suppose there must be some form of general discussion on this or some way to obtain an estimate? I've read through OpenCV DevZone, the OpenCV GitHub site, this site (OpenCV Answers), various other locations on the internet I could find, and of course the main OpenCV page (opencv.org).

The only rough estimate I have been able to figure is from looking at the previous releases it seems a version is released approximately every two months, and 3.0.0 was released June 4th, 2015, so 3.0.1 would most likely be released very soon, but this is clearly not a good estimation method.

Is there a forum somewhere where this is discussed that I missed? How is the decision of when to make the next release made? Is there a mailing list or similar I could get on where released dates are proposed or discussed? Is there any better way to estimate a next release date than what I mentioned in the previous paragraph? If anybody can provide additional information please respond.

If anybody is wondering about the particulars of why I'm concerned with the next release, I'd prefer to wait until I can re-do my installation tutorials on Windows 10 + OpenCV 3 + Visual Studio 2015, and OpenCV 3.0.0 does not include the pre-compiled binaries for Visual Studio 2015. Yes, I understand I can compile from source with VS 2015 and then use OpenCV 3.0.0, but for a beginner tutorial it would be much more understandable and consistent for an OpenCV beginner if I can start with the pre-compiled binaries, which I can't do until OpenCV ships with pre-compiled binaries for VS 2015.

No answer to your question but may be if you have $250K you Can direct OpenCV development/Strategy/priorities (see note 2013-04-06) :D)

There was an idea not to distribute windows binaries, only python/java binding libraries. So I'd recommend you to add build-from-sources step to your tutorials.

Also feel free to update/extend existing OpenCV windows installation tutorials: http://docs.opencv.org/3.0.0/d3/d52/t... and http://docs.opencv.org/3.0.0/d6/d8a/t...

As @LBerger stated, you can check weekly OpenCV meeting reports: https://github.com/Itseez/opencv/wiki... (wiki is still migrating from code.opencv.org, so you can check it too: http://code.opencv.org/projects/openc...)

Issue milestones can be interpreted as some kind of roadmap: https://github.com/Itseez/opencv/mile... . Currently, due date is not set for active milestones, but we are going to update them during adaptation to new issue tracker.

Rough estimation for 3.1 is Q4 2015, we have some tasks planned for this release.

so everything is moving to github, nice. When you are talking about the book in the meeting reports, I guess you mean this one, right. Do we have an estimation about when it is expected in full form, because I do not believe the one that it is mentioned in the link above.

I'm not sure, but this one looks more appropriate: http://shop.oreilly.com/product/06369...

ok, nice to see an upcoming book for opencv 3.x. Perfect.
