v1.1.4 - Auto-Update State Recovery & Live Search
LatestIntroducing a premium live search dropdown to instantly find wallpapers by name or tag. The background auto-update system has been completely rebuilt with robust state recovery, ensuring your downloads safely persist even if you leave the Settings page, and giving you manual control over when the app restarts.
v1.1.0 - Auto-Update Reliability
This critical update fixes our automatic update system for all future releases. We've also streamlined the interface by temporarily disabling work-in-progress AI features to focus on core stability.
v1.0.6 - Background Slideshows
Introducing the Slideshow feature! Select 3-5 of your favorite wallpapers and have them rotate at custom intervals. Includes a new System Tray integration to keep the slideshow running while the app is closed.
v1.0.5 - Ultimate Reliability
Added robust system-native fallbacks (PowerShell for Windows and AppleScript for macOS) to guarantee wallpaper application even when module binaries are restricted. Improved module bundling and cross-platform consistency.
v1.0.4 - Final Hotfix
Fixed the installation process to properly unpack native system binaries recursively while keeping JS source files compressed.
v1.0.1 - Engine Upgrade
Swapped legacy PowerShell wallpaper scripts for a seamless, cross-platform module. Poster now sets wallpapers significantly faster and lays the foundation for future Mac support.
v1.0.0 - Initial Release
The very first official launch of Poster! Complete with our fluid UI, high-fidelity local scaling via Sharp, and instant wallpaper applications.
