Because that's the last time somebody paid developers to do the
work involved in a public "release".

If you don't want to hear answers, then don't ask questions.

Nonsense.

Utter bullshit.  They do have bugs, but so do releases. Neither
is "supposed to have bugs".

Bah. Nobody intentionally checks in bugs.

There are no "stable releases" of Linux any more.  Active
development is being done in the "stable" tree.  There are no
more stable and development versions of Linux like there used
to be.

On the contrary, we are all from the world of commercial
products development.  That's what eCos is used for: developing
commercial products.  I've been using eCos to develop
commercial products for 7+ years, and the lack of "releases"
hasn't been even the least bit of a problem.

If you feel you're not capable of working from a CVS repository
and really want a "released" version, then that's what eCosPro
is:

No, not really.

Perhaps one of those RTOSes will meet your privilege management
requirement better than eCos.
