Windows will warn you about this installer

It will, and it is worth knowing before it happens rather than after. When you run the installer, Windows is likely to stop it with a blue window headed "Windows protected your PC", tell you that Microsoft Defender SmartScreen has prevented an unrecognised app from starting, and offer you a single button that says don't run it. Your browser may say something similar while the file is still arriving.

That warning is not about what is in the file. It is about the file having no code-signing certificate on it: Portman2's installer is not signed, so Windows has no publisher name to show you and no history of this file to go on — and an application it has never seen before, with no signature on it at all, is exactly the case that panel exists for. It says the same thing about every unsigned installer, including the harmless ones.

To go ahead anyway: choose "More info" in that window — which is where it shows the publisher as unknown — and then "Run anyway". If you would rather not take the software's word for any of this, check the checksum below first; that is what it is published for.

Checking the file you got is the file we published

The SHA-256 above is this exact installer's. Run the line below in PowerShell against the file you downloaded and compare the two: if they match, the bytes on your disk are the bytes on this server, and nothing altered them on the way. If they do not match, do not run it.

The server publishes the same number on the download itself, in an X-Portman-Sha256 header, and both come from the one row in the release table this page is reading — so this is a check with something behind it rather than a number printed beside a file.

What changed in this build

Find any photo by typing, let Portman2 recognise what is in your photos, and put them on every screen in the house.

Press Ctrl+F to search by album, tag, date, keyword or file name, with suggestions as you type.
Describe what you are looking for, "children on a beach" or "snow at night", and the best matches come first.
Automatic keywords: Portman2 recognises what is in each photo, on your own computer, with nothing uploaded. Choose the words it looks for and make it more accurate by judging a few samples.
Turn any keyword into a tag from its chip in the viewer, and Find similar can now look for the same kind of scene.
New photos are analysed by themselves once the library is idle.
Multi screen: choose what each screen shows, pin a photo to the TV with F2, show a photo's details full screen, or split a display into two or four.
Use tablets and phones as screens, and borrow another computer's screens when someone there allows it.
Style how every screen shows your photos: edge to edge or framed, a crossfade, and a blurred or gradient background.
The Conflicts tab can file a photo under the file's own date, and its buttons are simpler.
Settings reopens on the pane you last had open.

And fixes you may notice:

On a computer where the background host is serving, the Live page shows the picture again.
The download progress counts megabytes correctly.
Prompts and the colour picker open inside Portman2, instead of as separate windows.
A screen window no longer comes up full screen with its picture laid out for a smaller window.
