If I try to update my Opera to version 10.00 (release) I see that: [ebuild UD] www-client/opera-10.00 [10.10_pre4566] Portage thinks that the version 10.00 earlier than 10.00_pre4566. Reproducible: Always Steps to Reproduce: 1. emerge -p =opera-10.00
10.10_pre4566 that version was selected badly, and from a versioning p.o.v. it is correct. Won't break anything, so just tolerate this little issue :)
