After the removal of the first Oracle Database 12.2.0.1 Bundle Patch in May, the June 2017 Proactive Bundle Patch on Linux got released now:
What’s inside?
The Proactive Bundle Patch 12.2.0.1.170620 contains the June Database Bundle Patch and the June Grid Infrastructure Patch Set Update.

Proactive Bundle Patch – June 2017 – Linux – Oracle Database 12.2.0.1
More information about previous and future BPs?
First of all, the well known schedule for BPs (and of course PSUs) will be kept – so please expect the next Proactive Bundle Patch at the regular date in July. My reading of the June (and the removed May) BPs is simply that we wanted to release a regression tested accumulation of important patches and don’t let customers already live or testing with Oracle Database 12.2.0.1 not wait until mid of July.
This Proactive Bundle Patch is available on Linux only. The main July BP (and PSU) will be available on all platforms of course.

Do you know the reason this non-regular schedule (quarterly) was released in may, pulled, and then re-released in june? Could the changes just not make it for April 2017?
Bradd,
as we released 12.2.0.1 in March the changes couldn’t have made it into an April BP as the code freeze for the April BP was shortly after the release of 12.2.0.1 – and we have to regression test the BPs. But we don’t want to let early adopters wait until July. Therefore those non-reg schedule BPs got released on Linux only. And I can’t say anything about the reason but you shouldn’t worry – two of my customers have the May BP and run without issues (which is expected).
Cheers
Mike
