I've done a little bit of consultation with previous release managers, and reviewed various list archives and calendars. These consultations seemed to suggest some folklore that wasn't captured in our process doc - hence the proposed patch, below. I would like to tentatively propose the following schedule and policies for Xen 4.15. If you have opinions, please comment as soon as you can so that we can have an open dialogue. Comments must be submitted at the very latest by 1700 UTC on Wednesday the 2nd of December. Having never done this before, I am particularly interested in comments from previous release managers. ** DRAFT ** Friday 8th January Last posting date Patches adding new features should be posted to the mailing list by this cate, although perhaps not in their final version. Friday 22nd January Feature freeze Patches adding new features should be committed by this date. Straightforward bugfixes may continue to be accepted by maintainers. Friday 12th February **tentatve** Code freeze Bugfixes only, all changes to be approved by the Release Manager. Week of 12th March **tentative** Release (probably Tuesday or Wednesday) Any patches containing substantial refactoring are to treated as new features, even if they intent is to fix bugs. Freeze exceptions will not be routine, but may be granted in exceptional cases for small changes on the basis of risk assessment. Large series will not get exceptions. Contributors *must not* rely on getting, or expect, a freeze exception. Chinese New Year falls around the 11th-19th of February this year. In my plan above, that falls within the hard code freeze period. If we don't manage to get the tree to an acceptable quality level by the tentative codefreeze and release dates above, these dates will slip. I have not yet started tracking "big ticket" items, and bugs. I expect to start doing that starting after Christmas. NB the primary responsibility for driving a feature's progress to meet the release schedule, lies with the feature's proponents. If as a feature proponent you feel your feature is at risk and there is something the Xen Project could do to help, please consult me or the Community Manager. In such situations please reach out earlier rather than later. ** END OF DRAFT ** Thanks, Ian. >From b34f4ddace0b8d76d8c340a46288a2db79c99460 Mon Sep 17 00:00:00 2001 From: Ian Jackson To: xen-devel@lists.xenproject.org Cc: Andrew Cooper Cc: George Dunlap Cc: Ian Jackson Cc: Jan Beulich Cc: Julien Grall Cc: Stefano Stabellini Date: Wed, 25 Nov 2020 13:22:08 +0000 Subject: [PATCH] xen-release-management doc: More info on schedule MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This documents our practice, established in 2018 https://lists.xen.org/archives/html/xen-devel/2018-07/msg02240.html et seq CC: Jürgen Groß CC: Paul Durrant CC: Wei Liu Signed-off-by: Ian Jackson --- docs/process/xen-release-management.pandoc | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/docs/process/xen-release-management.pandoc b/docs/process/xen-release-management.pandoc index e1aa1eda8f..a5d70fed67 100644 --- a/docs/process/xen-release-management.pandoc +++ b/docs/process/xen-release-management.pandoc @@ -15,8 +15,10 @@ that they can have an idea what to expect from the Release Manager. # Xen release cycle -The Xen hypervisor project now releases every 8 months.
