[ome-devel] [ome-users] Release of OMERO 5.4.2

[Damir Sudar]

Hi Josh,

That's a bummer. I already upgraded since some features of 5.4.2 (e.g.
thumbnail display of large plates in OMERO.web) are critical to me.

So it sounds I should regularly restart OMERO.web to avoid this new issue?
On a moderately used system, how often is likely adequate? Is nightly
likely enough?

Thanks,
- Damir
