Yes, you're experiencing the bug I described. Until the bug is fixed
and the fix is released there is a workaround which will replicate the
old behavior:

- Administration -> Global System Preferences -> Local use -> New preference
- Create a system preference called "OpacLoginInstructions"
- Enter text or HTML in the "value" field and it should appear in the OPAC.
