upthread
upstream adj.
[common] Towards the original author(s) or
maintainer(s) of a project. Used in connection with software that
is distributed both in its original source form and in derived,
adapted versions through a distribution (like the Debian version of
Linux or one of the BSD ports) that has component maintainers for
each of their parts. When a component maintainer receives a bug
report or patch, he may choose to retain the patch as a porting
tweak to the distribution's derivative of the project, or to pass
it upstream to the project's maintainer. The antonym
`downstream' is rare.
