This is an important issue and it deserves careful consideration. This may just be semantics, but if by 90-day release cycle, you mean creating new tarballs for packagers to build from - fine. A new minor version bump should only occur WHEN: (1) A substantial new feature or capability is added/updated (e.g. Hal requirement dropped, etc...) (2) The user interface substantially changes (then all users will walk away anyway) (3) A collection of packages has undergone namechange (KDE -> TDE (or k->t) - avoid k->tde changes) (4) The build system has been significantly altered/updated. There are a plethora of examples where a "rapid fire", "rabbit pellet" release cycle has completely ruined packages, desktops and distributions. That being said, there is nothing wrong with maintenance releases of the form R14.0.0-[X+1] So long as there are no build differences to the packagers required within maintenance release. For example, upon R14.0.0-1 release the build requirements for each of the packages are frozen. Through the next 50 (or whatever number) maintenance releases (R14.0.0-1 -> R14.0.0-50) all packages will continue to build in the same manner as they built with R14.0.0-1. > The idea is to issue a maintenance release R14.0.x every 3 months, containing > bug fixes and minor improvements, and issue a minor release R14.y.0 every > year containing bigger improvements.

If a new major feature/capability is ready at 9 months or won't be ready for 18 months - making minor version number bumps "mean something" is important - otherwise it is just another "rabbit pellet" drop. Regardless of whether it is with a maintenance release or minor version bump, if a significant fix occurs, backport as soon as testing/signoff occurs.

NO "rapid fire", "rabbit pellet" releases. This is a disaster waiting to happen.

To tag releases to time is meaningless it is just a coincidental moment in time without reference to feature/capabilities, compatibilities or API. You cannot do naming conventions like that without breaking packaging. While many build system can "support (cludge)" non standard names, this can really create havoc. Package/Release naming should always subscribe to: package-major.minor.micro-rel.arch.(compression http://www.tldp.org/HOWTO/html_single/Software-Release-Practice-HOWTO/#naming package-major.minor[.micro]-qualifier.arch.(compression) Good example: https://community.jboss.org/wiki/JBossProjectVersioning Any reference to time is meaningless. See http://programmers.stackexchange.com/questions/77637/yyyy-mm-dd-hhmm-vs-major-minor-revision, comment 12: [YYYY].[MM].[DD].[hh][mm] has no meaning. It's just a coincidental binding between a moment in time and a release > Also, a side-effect benefit would be that TDE would look more active to the > general public with Ryy.x release numbers than R14.0.x release numbers, since > the last would probably be thought of as "nothing major, just minor fixes". > > Looking forward for your opinions. Cheers Michele > From a technically competent desktop standpoint, no one should care if TDE "has the appearance" of an active project, blah, blah, blah. The only thing that matters is that it is technically current, well tested, stable and a desktop that meets user expectations of providing all of that in a package that maintains the traditional KDE3 look, feel, behavior and performance. Do that and all the recognition a desktop of that caliber deserves will follow. There is no faster way to destroy all of that hard work than to subscribe to some meaningless rabbit pellet release cycle. I think the suggestion of a 90 day maintenance release schedule is more than sufficient for bug fixes, etc. I further think that before we began to talk about minor version/version bumps we identify what the goals are for the next minor version/version bump and then look at what a realistic time-frame is given the manpower/skill available to get it done. Looking at timetables before that is done is somewhat putting the proverbial "cart" before the proverbial "horse"... Don't mistake any of this as shooting the messenger, it's not, I commend all the hard work and thought that is put in this direction. But, when asked for opinion, this is the cumulative total you get on this issue from nearly two-decades of Linux/OSS project involvement. TDE is a fantastic project and desktop and should be managed going forward free from artificial timelines and cycles that have been the death-nail of so many other good projects that have come before it. -- David C.
