Abstract
Cargo, the software packaging manager of Rust, provides a yank mechanism to support release-level deprecation, which can prevent packages from depending on yanked releases. Most prior studies focused on code-level (i.e., deprecated APIs) and package-level deprecation (i.e., deprecated packages). However, few studies have focused on release-level deprecation. In this study, we investigate how often and how the yank mechanism is used, the rationales behind its usage, and the adoption of yanked releases in the Cargo ecosystem. Our study shows that 9.6% of the packages in Cargo have at least one yanked release, and the proportion of yanked releases kept increasing from 2014 to 2020. Package owners yank releases for other reasons than withdrawing a defective release, such as fixing a release that does not follow semantic versioning or indicating a package is removed or replaced. In addition, we found that 46% of the packages directly adopted at least one yanked release and the yanked releases propagated through the dependency network, which leads to 1.4% of the releases in the ecosystem having unresolved dependencies.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
