Release Notes
What's new, improved, and fixed in every release.
Latest
v1.8.5
- A library pointed at a folder with loose model files at its top level could end up filing every new top-level folder under one of those files' records. The app now repairs this on launch and tells you what it moved.
- Importing a library folder onto itself is refused before anything runs. With Replace and Overwrite Files turned on, this used to delete the folder's files.
- Dropping files on the Library crumb now says why nothing moved and how to move them instead.
v1.8.4
- Bulk Tag is now Bulk Organize: each rule can also set a category and add the matches to collections
- The library remembers your last sort, so it opens sorted the way you left it
- Windows fit the screen on scaled and small displays, and the title bar stays draggable while a dialog is open
v1.8.3
- New Bulk Tag tool adds tags to many files at once by matching their names
- Imports now open the folder you imported into, so everything you just added is on screen
v1.8.2
- 3MF files now render with their embedded colors, including Bambu Studio and OrcaSlicer painted models
- Rotate pieces directly on the build plate, with a collapsible controls guide on every 3D view
- New Open With menu launches files in any of your configured slicers
- Fixed creator packs containing nested zips importing as an empty folder
- Optional surveys and product-news emails, with preferences you control in the app and on the website
v1.8.1

v1.8.0
- Projects — track a print from build plate through finishing, with photos and notes along the way
- Completed Prints is now Print Photos, everywhere in the app
- Removed the free-tier minigames display - just started feeling to silly as the app keeps growing.
- Fixes for blank photo tiles and thumbnails stuck on "Generating…"
v1.7.7
- More convenient print tracking — mark files printed and adjust print counts right from the library, plus a new print-status filter

v1.7.2
- Board view with three columns: In Progress, Up Next, and Planned — so you can see at a glance what's being worked on, what's coming next, and what's confirmed
- Considering tab — ideas being weighed, sorted by votes. Search to find what you're looking for, and if it's not there, suggest your own feature right from the page
- Vote on the website — you can now sign in on 3dprintmanager.com/roadmap and vote directly, not just from the app
- Shipped & Not Planned views — see what's already been delivered, and what's been set aside (with voting still open, so a "no" can become a "yes" if enough people want it)
v1.7.1
- Tracked the crash to a race between the renderer and background cleanup of 3D preview surfaces deep inside two of the UI libraries the app is built on
- We patched two libraries directly and now ship the fixed builds with the app, and we've submitted the details upstream so every app using them can eventually benefit
