Upstream Contribution
Noun · Open Source
Definitions
A patch, fix, feature, or other work submitted back to the original project rather than kept only in a private fork or downstream package. Upstream contributions reduce divergence and spread maintenance cost more fairly.
In plain English: A change sent back to the original project instead of being kept only in a local copy.
Example: "They turned the local workaround into an upstream contribution so every downstream user could benefit from the fix."
