Phocus 4.2.1 for Mac Has Eleven Words of Release Notes

Hasselblad released Phocus 4.2.1 for Mac on July 15th. As I write this, their own Phocus product page still lists 4.2 as the current version. The build is on their CDN and in the API that feeds the downloads page. The page just hasn't caught up, and going on past form it may not for a day or three.

The only reason I know it shipped is that Phocus told me itself. The update notification system arrived in 4.2, six weeks ago, and it works: launch the app and it says there's a new version. Credit where it is due. Hasselblad built the channel that actually fires, and right now it is outperforming their own website.

There are no release notes for 4.2.1. I want to be precise about that, because it sounds like a complaint and it's a measurement.

Key finding: Phocus 4.2.1's release notes are the 4.2 release notes with a new date and eleven words added. The document grew from 1,479 words to 1,489. The only stated changes are faster thumbnail loading and "fix other known issues," which does not say which ones.

What's Actually In Phocus 4.2.1?

Hasselblad ships a read-me PDF with each Phocus release. I pulled both the 4.2 and the 4.2.1 versions and compared the text.

They are the same document. The 4.2.1 read-me is the 4.2 read-me with the heading changed, the date changed from June 2nd to July 15th, and one changelog entry added:

• Optimize thumbnail loading speed and rendering quality
• Fix other known issues

Eleven words. The document went from 1,479 words to 1,489. Nothing else changed. The rest of the diff is Hasselblad re-typesetting the PDF, so the line breaks fall differently and the bullet characters became plain indents, but not one sentence of content moved.

This matters when you open the file, because the read-me still carries a section headed "New features in 4.2" describing the redesigned Output Presets dialog, the brush mask eraser, negative Highlight Recovery and Shadow Fill values, and the update notification system. Those shipped in June. Skim the document and it reads like a feature release. It isn't.

For comparison, 4.1.2 came with eleven itemized changelog entries, 4.1.1 with five, 4.0.1 with seven. This one has two, and four of its eleven words are "fix other known issues."

Which Known Issues Did It Fix?

The read-me does not say.

That matters more than usual right now, because there are open issues against 4.2 worth knowing the status of. The one I've written about most recently is Phocus 4.2 rewriting the EXIF Model tag on import, which breaks DxO PureRaw on files that pass through Phocus. Whether 4.2.1 touches that is not something the read-me will tell you.

The one concrete claim is thumbnail loading speed and rendering quality. That's a real area with a real history: thumbnail rendering is where the 4.1.2 color preview regression lived, and it's the kind of code path where a change made to improve speed can alter what you see before you open a file.

I'm retesting the open issues against this build and will follow up with what actually changed. That's the only way to find out, since the changelog has decided not to say.

Should You Update?

Probably, with one caveat. Point releases are low risk and the thumbnail work is likely a straight improvement. But 4.2 is the release that started rewriting EXIF on import, and nothing here says that stopped. If you run Phocus alongside DxO PureRaw, or anything else that depends on the camera model tag surviving intact, hold your workflow steady until I've confirmed the behaviour either way.

Phocus has no downgrade path. If you update and something breaks for you, going back means finding the old installer yourself.
