[db-wg] Improvements to RIPE Database Software Release Management

Dear Tim,

Thanks for the input, we will for sure have a look at the possibility of using an RSS feed for the release announcements, great idea. We also thought we could use Twitter as well.

When it comes to the test environment, our plan is to utilise this for public testing of major releases. We understand that there is a need for users to test their implementations when we introduce or change functionality; therefore we'll leave any major release in the TEST Database environment for a fixed time before deployment in the production RIPE Database.

With bug fixes, on the other hand, we would like to apply these to the production RIPE Database as soon as they are ready. For this type of fix we would use minor releases that only contain the actual fixes and does not introduce or change expected functionality. And as always, we produce accompanying release notes detailing what is contained in all releases, whether major or minor.

Kind regards,

Johan Åhlén
Assistant Manager Database

Also, will the releases be applied to the test environment ahead of the production environment as they currently are?

For instance, with a modern API like RDAP we might have bi-weekly major releases and weekly minor releases to quickly respond to changes in the specification. With the NRTM feed, there might be just one major release per year or even less.

We would also have "major releases" where functionality is added, changed or removed. With major releases we would keep the minimum two-week user test period leading up to the production release as stated in the previously proposed release procedure. With any minor release, we would put it in production as soon as it's available. Most bugs affect some users. Rather than trying to determine urgency based on numbers of users, size of users, number of networks affected, importance of functionality affected, etc., we would treat all bugs the same. In short, if someone reports an issue to us, we fix it right away. This process has generally worked well over recent years.
>> 
>> - Improve the test environment. We know that users would like to have their real data to do proper testing. To solve this issue, we propose to use snapshots of the current database for this purpose.
>> 
>> - Improve communication surrounding new releases. This covers all documentation and how we inform users about changes.
