## Notes

---

### [mdeslaur](https://launchpad.net/~mdeslaur)

in Oneiric+, rails package is just for transition

---

### [seth-arnold](https://launchpad.net/~seth-arnold)

Only 3.x.x is affected; earlier and 4.0.x are safe
The patch standardizes some log handling across multiple packages,
but the security fix looks restricted to just one line in action mailer:
info("\nSent mail to #{recipients} ...
the other packages can be left alone.
