v1.1.0

Release Notes

Welcome to PhotoMapAI, an AI-based image manager. See Features for a quick introduction, Installation to get PhotoMapAI installed on your home computer, and User Guide for usage and configuration.

PhotoMapAI Version 1.1.0

This is a big feature release — the highlight is a much smoother install experience on Macintoshes, Windows machines and Linux boxes. In addition, since the previous 1.0.5 release there are 22 new features and dozens of fixes large and small.

⭐ New install experience

• Signed, double-clickable desktop installer for macOS, Windows, and Linux (#300). No need to install Python, CUDA, or anything else first — on first launch it downloads a private Python plus the AI libraries, starts the server, and opens your browser automatically. Later launches start in seconds.
• Reliable first-run setup, everywhere. The launcher installs its private Python and required libraries, avoiding interfering with other software installed on the machine.
• GPU "just works": an NVIDIA GPU is detected and used automatically. You no longer need to install the CUDA Toolkit — only a recent NVIDIA driver. Apple Silicon acceleration is automatic too.
• Python 3.14 support (#258).

🗺️ Semantic map (UMAP)

• Automatic cluster labeling — clusters are now named by content (#234).
• Per-image tags in the hover popup (#262).
• Album switcher built into the semantic-map titlebar (#287).
• Smooth zoom everywhere: custom scroll-wheel and pinch-to-zoom that work across all browsers, including Safari and iOS touch (#312).

🔎 Search & discovery

• In-app Back button + browser back/forward for navigating your slide history (#241).
• Encoder model download progress is now displayed in the album UI during indexing (#308).
• Platform-aware default encoder for new albums (#307).
• Broader auto-tagging vocabulary, with an opt-out toggle (#251).
• Search and other server errors now appear as toast notifications instead of failing silently (#278, #288).

🖼️ Slideshow

• Smarter end-of-show behavior: sequential mode stops cleanly on the last slide (with the play button grayed out), while shuffle mode reshuffles endlessly (#293, #296).
• Shuffle autoplay stays alive through long runs and buffer rebuilds (#297, #313).

🎯 Curation

• Grid view plus an automatic UMAP on completion, and a ~200× speedup in BLOCKS curation (#281).

🏷️ Metadata

• EXIF drawer now shows DateTimeOriginal, Orientation, and image dimensions (#279).
• Clickable reference-image thumbnails in the metadata drawer (#238).
• Better handling of InvokeAI v5 metadata and assorted format edge cases (#267, #268).

⚙️ Preferences & quality of life

• Per-device, server-side UI preferences — your layout choices persist per device (#284).
• Move to Trash / Recycle Bin option for image deletion, instead of permanent removal (#273).
• An update badge on the About button when a newer version is available (#280).
• Cached reverse-geocoding for faster GPS location lookups (#272).

🔒 Notable fixes

• Closed XSS, path-traversal, and partial-write security risks (#242).
• Resolved indexing/concurrency race conditions and VRAM-release issues (#243, #271).
• Numerous UI leak and stability fixes across the slideshow, curation, and grid views.
• In-app "Update" now works for launcher installs (#327). Installs created by the desktop launcher run in a pip-less environment, so the About → Update button previously failed; it now upgrades via uv instead.

Plus internal refactors, CI repairs, and frontend cleanups under the hood.

Upgrading from the 1.0.6rc1 pre-release? If you installed an rc build with
the desktop launcher, the in-app Update button may fail with
No module named pip (that older build predates the fix in #327). To get onto
1.1.0, just re-run the PhotoMapAI launcher with --reinstall — it reinstalls
the latest release cleanly. After that, the in-app Update button works normally.
Stable installs (1.0.5 and earlier) are unaffected and can update in place.

Full Changelog: v1.0.2...v1.0.3

v1.0.2

This release adds a couple small features and corrects several bugs.

Feature: Album Locking

This version introduces a new command line option, --album-locked which accepts one or more album keys separated by spaces. If this option is present, PhotoMapAI will only allow the user to select one of the listed albums. All functions that modify the filesystem, including changing albums, deleting images, and moving images around, are disabled. Use this to give your friends and family access to some, but not all, of your configured albums.

Feature: Display InvokeAI Workflow Metadata

This version now displays metadata added to images by InvokeAI workflows.

Bug Fixes

• Deleted bookmarked images no longer persist in the grid view.

Installation

See Installation for full instructions. Prebuilt binaries with accelerated GPU support can be downloaded from here.

What's Changed

• (chore) fix artifact upload step (again) by @lstein in #183
• (enhancement) detect and handle metadata generated by Invoke workflows by @lstein in #186

Full Changelog: v1.0.1...v1.0.2

v1.0.1

This is a bugfix release to address a number of small issues in 1.0.0. The 1.0.0 release notes are reproduced here:

What's New

This release of PhotoMapAI adds many new features, bug fixes, and performance enhancers.

Image Dataset Curation

A completely new image curation panel was contributed by @NMWave. This feature is designed to assist in curating images for use in AI generation and classification models. This mode automates the selection and maintenance of a balanced and diverse set of training images. See Dataset Curation for more information.

Bookmarks

You can now "star" an image and add it to your favorites. You can then filter on favorites, download a zip file archive, move the favorites to a new folder, or delete them en masse.

Slideshow modes

You can now easily select whether the slideshow shows images chronologically or in shuffled order. Simply right click on the slideshow button (on desktops) or long press (on tablets) to choose which mode is active.

More Semantic Map options

You can now control whether the semantic map minimizes itself when selecting a cluster, and conveniently show, hide and clear highlighted images. In addition, the map navigation icon menu has been reorganized to make it more easily accessed on tablets.

Grid View bugs fixed

Multiple strange behaviors in the grid view, including unexpected backwards navigation, loading slowness, and misordered images have now been fixed. Performance is improved as well.

Enhanced cluster display and navigation options

The currently-selected image's cluster is now shown in the metadata panel. Clicking on the cluster name will select other images in the same cluster. In addition, the cluster name and size are shown in the thumbnails that appear when you hover over a point in the semantic map.

Better metadata support for InvokeAI

The metadata display panel has been updated to support images generated by legacy versions of the fantastic InvokeAI generative AI image creation package.

Improved album management

The Album Manager now appears instantly when you click its button in the Settings panel. It also adds a "Back" button to return to Settings when desired. In addition, the user interface for the directory browser has been cleaned up to be more intuitive and responsive.

Installation

There are several ways of installing this application. Please see Installation Instructions as a guide.

If you choose to install an executable bundle, you'll find CPU-only executables under Assets below. The GPU-accelerated versions can be found here: PhotoMapAI v.1.0.1 Executables
