Xen_Project_Release_Features page update?

Xen_Project_Release_Features page update?

[Julien Grall]

Hi Lars,

As I understand from Xen 4.10 [1] , we are going to use SUPPORT.MD or 
the list of features existing.

I guess we should retire the features matrix [2]? But this also means 
that we have not anymore an easy way to know until when a release is 
supported/security supported. Do you have any plan for this?

Cheers,

Is there any human-friendly form of SUPPORT.MD?
Xen_Project_Release_Features is really convenient place to check about
support for various features. Especially when trying to answer "what Xen
version I need for feature X", or "is my Xen new enough for X"
questions.
Maybe Xen_Project_Release_Features could be automatically generated from
SUPPORT.MD? Even subset of informations from SUPPORT.MD would be
useful...

Q: Why is top-posting such a bad thing?

  Correct.

  Not yet. It was predicated on:
  a) Creation of an equivalent file based on SUPPORT.MD from different branches
  b) A tool to create a webpage

  Not yet: this was meant to happen shortly after the 4.10 release, but Spectre/Meltdown derailed this
  Ian Jackson was going to do the work to pull a script together.
  I think he may have started (or at least looked at this)
  
  @Ian, @Juergen: we should track this in the 4.11 Release Task list to make sure it doesn’t get dropped

  Agreed. Now SUPPORT.MD has been migrated and improved from Xen_Project_Release_Features

That was the original plan. In fact – once we have backported SUPPORT.md for several releases – 
and have the tools, it should be possible to create a table and/or individual pages presenting the 
information.

But, as I said, at the moment this is not as important as Spectre/Meltdown fixes

Lars
