Hasselblad released Phocus 4.2.2 for Mac on August 20th, five weeks after 4.2.1. The build is on their CDN and in the downloads API that feeds their website, which is where my release monitor picked it up just before midnight Eastern.

This time there is an actual changelog. Seven lines of it. That is a step up from the eleven words that accompanied 4.2.1, and two of the seven lines are about HEIF, which is the format Hasselblad's whole HDR story depends on. I installed it this morning and have had it open for less than an hour, so this is the read-me, a bundle diff, and first impressions.
Key finding: Phocus 4.2.2 for Mac (August 20, 2026) lists seven changes: in-app language switching, Ctrl + scroll smooth zoom, full editing of re-imported HEIF exports, batch import work, smoother thumbnail browsing, faster Exposure V1 adjustments, and a second-HEIF-export fix. The bundle diff adds an undisclosed in-app update downloader.
What Phocus 4.2.2 Changes, According to Hasselblad
The read-me that ships with 4.2.2 is the 4.2.1 read-me with the heading changed, the date changed from July 15th to August 20th, and one block added under the changelog. The document went from 1,488 words to 1,546. Here is the block, verbatim:
- Support in-app language switching
- Support smooth zoom with Ctrl + mouse scroll wheel
- Support full editing for re-imported exported HEIF files
- Optimized experience for batch import and batch modification
- Improved image switching smoothness when browsing thumbnails only
- Optimized image adjustment performance for Exposure V1 gears
- Fixed issue causing failure on second HEIF export
- Fixed other known issues
Everything above that block is unchanged. The "New features in 4.2" section still describes 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. If you skim the PDF it still reads like a feature release, and it still is not one.
I keep a running comparison of every 4.x read-me against what testing shows actually shipped on the release notes ledger. 4.2.2 gets its entry there once I have been through the build.
Researching and writing the blog and page posts I produce takes up a lot of my time and costs me money for software subscriptions, tooling, and other incidentals related to running a business.

The Two HEIF Lines Are the Ones That Matter
If you shoot an X2D II and export HDR, the HEIF lines are the two that touch your workflow.
"Support full editing for re-imported exported HEIF files." The wording implies that the tool set you got on a re-imported Phocus HEIF was restricted until now, and that 4.2.2 lifts the restriction. It does not say which tools were missing. That is the first thing I will check: export an HDR HEIF from a 3FR, re-import it, and compare the Adjust panel against what 4.2.1 offered on the same file.
"Fixed issue causing failure on second HEIF export." That one is a straight bug fix, and it is not a bug anyone has reported to me. The phrasing suggests the first HEIF export in a session worked and the second one failed. If you hit that in 4.2 or 4.2.1 and worked around it by relaunching, this is your fix. If you have more detail on when it triggered, I would like to hear it, because I want to confirm the fix rather than take the read-me's word for it.
HDR HEIF is the delivery format Hasselblad pushes hardest for the X2D II, and it has had the least stable export path through 4.x. Phocus 4.2 fixed the 4.1.2 export dimension cap that silently shrank every HEIF, and 4.2 itself claimed "improved highlights for exported HDR HEIF / UltraHDR images". Two more HEIF fixes in 4.2.2 says the format is still getting engineering attention, and still needs it.
In-App Language Switching and Ctrl + Scroll Zoom
Ctrl + mouse scroll wheel now zooms smoothly in the Viewer. Phocus already had stepped zoom and the one-click zoom controls from 4.0. Smooth scroll zoom is what anyone coming from Capture One or Lightroom reaches for first. Trackpad pinch zoom is also smooth in 4.2.2 and works without selecting the Zoom tool. I cannot say for certain that it did not before; the pinch handler exists in the 4.2.1 binary too, and the changelog says nothing about it, but it did not feel like this in 4.2.1.
Language switching moves the UI language into the app instead of leaving it to the macOS system language. It takes effect after a relaunch (the bundle diff below has the evidence).
Neither feature is documented anywhere except this changelog line. The Phocus manual still stops at 3.8.
Performance Lines: Batch, Thumbnails, and Exposure V1
Performance claims are the hardest part of a read-me to verify, because there are never numbers.
Batch import and batch modification. "Optimized experience" could mean anything from a progress bar to a rewritten import path. Given that 4.2's import is the release that started rewriting the EXIF Model tag on every imported 3FR, the import path is where I will be looking hardest.
Thumbnail-only browsing. 4.2.1 introduced a persistent thumbnail cache that did not exist in 4.2 (a 5 GiB disk tier plus an in-memory tier, described in six words in that release's read-me). "Improved image switching smoothness when browsing thumbnails only" reads like a follow-on to that work. The browser was already noticeably quicker in 4.2.1. This build moves it a long way further: scrolling and arrowing through a folder of 3FRs in thumbnail view is, anecdotally and after ten minutes, the fastest Phocus has ever felt on my Mac, to the point where browsing stops being the part of the app you put up with. I have no measurements yet, and that is the first thing I will put numbers on.
Exposure V1. The read-me says "Optimized image adjustment performance for Exposure V1 gears". "Gears" is almost certainly a translation artifact. Exposure V1 is the oldest of the four algorithm versions the Exposure tool can run, kept for compatibility so that images edited in early Phocus versions render the same way when reopened. V4 is the default for anything imported into Phocus 4.x and the only version that supports the HDR pipeline. So this line matters if you have a large archive with old sidecars, and not otherwise. The version selector and what each one changes are covered in the Phocus guide.
Have you seen the guide? I've published Essential Phocus 4.x for Mac - 85 topics across 8 sections and 250 pages covering everything from HNCS color science to HDR workflows. It's the reference manual Hasselblad hasn't updated since 3.8. It's $49, and updates are included.
Which Known Issues Does Phocus 4.2.2 Fix?
The read-me does not say. "Fixed other known issues" is back, and as with 4.2.1 it names none of them. These are the open problems I track that 4.2.2 does not name:
- Import rewrites the EXIF Model tag. Since 4.2, every 3FR that passes through Phocus import has its camera model string rewritten, which breaks DxO PureRaw on those files. Hasselblad has a support case on it. "Optimized experience for batch import" is the line that might touch this, or might not. That retest is next.
- Import adjustment presets are not applied. The correction I published on 4.2 stands: the preset you pick at import is not what ends up on the file. Hasselblad has a case open on that too.
- HNNR output filenames get a spurious numeric suffix. Hasselblad said it was investigating in April. Still present in 4.2.
- Import over SMB blocks the main thread. Engineering confirmed this one and queued it for a future release. Nothing in the read-me suggests this is that release.
All four are in the Known Issues tracker with reproduction steps and case history, and each will get a 4.2.2 status line once retested.
What the Read-Me Does Not Say: The Bundle Diff
I compared the 4.2.2 application bundle against 4.2.1 file by file before installing. Of 1,309 files, 103 changed and 1,116 are identical. The framework list is the same. The signing identity, entitlements, and notarization are the same. Most of the changes are small. These are not.
Phocus can now download its own updates. The 4.2 update notification was a dialog with a button that sent you to the website. The 4.2.2 string table for that dialog grew from 7 entries to 19, and the new ones are "Downloading Phocus Update", a percentage progress string, "Download complete", "Download failed", "Retry", and "Download verification failed". That is an in-app download-and-verify flow, and it is not in the changelog. I will confirm how it behaves the next time Hasselblad ships something.
The language switch is real and needs a relaunch. The main binary gains a SelectedApplicationLanguage preference and a "restart now / later" prompt that did not exist in 4.2.1. No new language bundles were added; the same eleven localizations ship as before, so this is a switch between the existing translations, not new ones.
The lens correction maps and colour tables have lost their names. Phocus ships 59 per-lens geometric correction maps and 26 sensor colour tables inside two of its frameworks. Through 4.1.1 those were readable XML files with readable names (GMapXCD38.xml, LUTTable100MP.xml). 4.1.2 made the contents opaque, same names, same sizes plus 20 bytes, and nobody mentioned that either. In 4.2.2 the names are gone too: every one of the 85 files is now a random twenty-character .dat, and the two frameworks that read them gained the strings "white-box decrypted" and "plaintext fallback". I read that as Hasselblad tightening the encryption on its calibration data and removing the last clue about which file belongs to which lens. I have not decompiled the loader, so treat the mechanism as an inference; the rename and the new strings are facts you can check yourself with find and strings.
None of that affects how your files render. It does affect anyone trying to study how Hasselblad's lens corrections and colour science work from the outside, which is a subject I write about, and it tells you something about where Hasselblad's engineering attention went in a five-week point release.
There is also a third neural denoise bundle, PBNeuralNetworkDeNoise_MLDenoise.bundle, sitting next to the two that shipped before, built against the macOS 26.1 SDK. The existing two are unchanged. I do not know what model it carries or whether HNNR output differs, and I will test whether it does.
Ctrl + scroll zoom, the HEIF re-import change, and the batch import work left no new strings I could find. That does not mean they are absent; it means they are implemented inside code paths that already existed, and the only way to check them is to use the app.
Should You Update to Phocus 4.2.2?
That, as usual, depends on your appetite for risk, but this time I lean yes, and not for the HEIF lines. The browsing speed alone makes 4.2.2 worth installing; it changes how the app feels to work in, and that is before anyone has measured it. The HEIF fixes are a bonus if they hold up. Point releases in the 4.x line have been low risk with one exception, 4.1.2, which shipped two regressions that took a full release to undo, so I still want a day or two of use before calling it clean.
The one group that should wait is anyone whose workflow depends on the EXIF Model tag surviving import (DxO PureRaw, or anything else that reads the camera model to pick a profile). Nothing in this read-me says that behaviour changed, and the retest is next.
Going back is easier than it sounds. Phocus has no downgrade button, but downloading the previous installer and installing it over the new version works. Every 4.x build is still on Hasselblad's CDN; the version history has the links.
4.2.2 is installed. The retest results go into the Known Issues tracker and the ledger as they land, and if anything in this build turns out to be bigger than seven lines, it gets its own post.
