-Smoother app performance through concurrency enhancements

-Improved Share Menu functionality

-iPhone: Easily access printer settings from the fullscreen sidebar with improved transitions

-Generate Previews for STL/OBJ Files in Files App -Future Proof: Swift 6 compatible -UI Enhancements: Predefined Color Themes -Slice View: Round slices view selectable by configuration item -Tap a slice to view its G-code

- Document support for storing your arrangements with a new p3d-file format - Performance boost: Render code speedup for smoother display animations - UI Enhancements: More responsive single tap - Support imperial units as user choice as alternative to metric system - Reworked play control view for a more compact design - Overload Plus button with menu options for added convenience - Print object info view accessible via info-button

- Hotfix for startup error on older devices - Improved startup speed

- Easily find Moonraker/OctoPrint servers through Bonjour. - Edit the Title/Printer Address/API Key with a simple tap, no need for a long press. Customer Wishes Implemented: - Seamlessly export a combined STL file of your current build plate content. - Effortlessly export the current printer and process configurations.

- localization for several selected languages - add dedicated gcode editor view in printer view

- SW Update check is performed once a day coming out of background in addition to start up - Fix for slicing error using Prusa MK3S+ template (github issue #13)

- Fixed: Volume/Surface calculation has been wrong for objects with more than 1000 triangles

- gcode files can be opened and displayed - SW version check on App start to help you keep up to date - Fine tune sidebar layout - Size of printer file list symbols standardized - fix: field crash for too short STL files (6-79 Bytes) - fix: gcode moves in preamble could impact display of slice layers

- Rework the sidebar in order to remove the problematic SwiftUI List - Ask user permission before opening an external link - Left Dock has grown up into an elaborate toolbox placed at left bottom, which display/modifies object unit, position, euler angles, scale, rotation modes

- Fix slice flickering, which has happened as soon as any slice type has been disabled

- First version with two finger TouchPad support. For object modification need to press OPTION-Key, too. - Unlimited undo with redo - Optimized memory management to free up memory for older devices - While resizing the 3D view screen updates are suppressed to avoid memory usage spikes on some devices - change layout of PlayControlView - Deselecting an object is now faster - Allow multiple files to be imported at once - Auto resize of loaded files being too large or too small (within three powers of ten) - replace buggy iOS UIDocumentFilePicker with iOS UIDocumentBrowser

- further speed up of slice view, again mainly targetting devices with A9/A10 chip - disable snapshot button, while slicing is ongoing - for slice print simulation and play position at e.g. 10h with a slow speed factor like x0.01, the play position has not advanced anymore

- Print Object dimension output as floating point and not as integer - As per twitter feedback: fix load of files with 1 Mio+ triangles - Improve reliability of print object selection per tap on older devices - Increase timeout for slicer engine in order to support larger files

- print object: out of print bed red shading is now along the boundary and not triangle based - reduced startup time due to parallel shader compilation - speed up of print object loading with nearly one million triangles

- faster compute GPU algorithm - mainly for older devices - so that part loading for large parts is noticeable faster - add missing update of the view on slice filter selection - reduce memory usage - avoid slice view flickering on older devices by better management of visible slices

- toggle print object info view on tap of selected object - obstrusive alert is replaced by a friendlier info box to report about mesh errors - calculate and show triangle count, size, surface area, volume for print object - support locking rotation for print object - Left dock's duplicate/delete functionality are taken up by toolbar's plus/trash - Fix startup bug specific to iOS version 15.x

- fix double tap behavior of timeslider - fix timeslider: layer boundary detection has worked only after slice step forward/backward has been used - fix transparent black printbed on printer change, if camera is below printbed - increase printbed negative z as depth resolution of 32 bit float is at its limit - adjust camera clip planes dynamically. This avoid slice flickering due to depth resolution limitation.

- Process Configuration: Sections can be collapsed - disable print object selection while slicing - Process Configuration: Extend tests and fix identified issues - possible fix for app crash in the field during onboarding - improved 3D view touch interaction on older devices - fine tuned slice presentation - prevent visible glitch on change of printer - memory leak fixed - internal: faster hit testing on print object

- fix snapshot feature

- Fix: red extruded slice cool down works again - Fix: reduce touchable timeslider area to visible width for high resolution devices - Complete rework of slice presentation in order to show sliced model in full at once

- Fix startup error for older iPads/iPhones (Apple3/4/5 GPU family, perhaps Apple6 GPU family - means A9-A12, perhaps A13): "Encountered unlowered function call to air.simd_min.u.i32".

This is our Xmas iceberg release. Only 10% of the changes are user visible... Here is our (most likely not) complete list of user visible changes: - Pan mode: in lower part of 3D view, panning will perform rotation around z-axes - Object movement is now done with two finger pan - Display rotation axes for selected object - Select fixed/automatic rotation axes mode via left dock button submenu - View rotation is not limited for eye point to stay above the print bed. Printbed is transparent, if viewed from the bottom - Night sky rotation has been corrected. - Stars of night sky are based on the Bright Star Catalogue (9096 stars). Correctness not tested due to lack of astronomer in the team. - Allow timeslider to be selectable, which works in iPhone safe area and iPad with keyboard/touchpad - iPhone: extend into safe area of screen - Printer upload provides error feedback, if print server could not be reached - Initial view by double tap is better adjusted to actual print bed/print object size - Faster placement of new print objects - disable import, as soon as any print object is outside the allowed print bed area - finally welcome/onboarding screen, which may be used to announce changes in subsequent releases - limit movement of print object within allowed print bed area - Toggle between two different camera positions on double tap - pixelated forbidden area for round print bed resolved - iPhone: solved too small gcode view in portrait mode
