Redmine 3.0.3 and 2.6.5

Redmine 3.0.3 and 2.6.5 are maintenance releases that fix several issues for 3.0.x and 2.6.x users ([[Changelog]]).

Redmine 3.0.3 also fixes a regression introduced in 3.0.2 that prevents users who disabled the % done field from creating/updating issues (issue validation fails with ”% done is not valid” error message).
