Rhinoceros  filed an orphan request for jalview :
10 months out of date. Package has been flagged for 2.5 months. No response to further comments two weeks ago (and other comments in the past). Maintainer has historically lagged behind upstream releases. Previous two versions (2.10.3, 2.10.4) lagged two months behind update, the one before (2.10.2) was totally skipped (was current for three months). The previous version was six months behind (2.10.1). Previous (2.10.0) was totally skipped (current for 7 weeks)… etc., etc.
