Unlike major annual releases (v10, v11), point releases like 9.4 focus on bug fixes, camera support, and performance. Here is the changelog for version 9.4.0.10:
1. Performance Optimizations (The Big One) Users on Windows x64 systems reported significant speed improvements in the Develop module. Adobe finally patched the "sliders lag" that plagued earlier 9.x versions. Scrubby zoom and brush adjustments feel noticeably snappier in this build.
2. New Camera & Lens Support This update added raw support for several cameras released in mid-2020, including:
3. Tethered Capture Updates Added tethering support for the Nikon Z5 and Fujifilm GFX 100.
4. Bug Fixes
It is important to understand where version 9.4 sits in Adobe's lineup: Adobe Photoshop Lightroom Classic 9.4.0.10 -x64...
Lightroom 9 stores edits in a catalog (.lrcat) – not in the original photo.

Adobe Photoshop Lightroom Classic 9.4.0.10 is a stable, mature release favored by professional photographers who require robust tethering support and localized file management. While newer versions have since been released (introducing AI-powered masking and Denoise features), version 9.4 remains a highly capable tool for raw processing and library management.
Adobe Photoshop Lightroom Classic 9.4.0.10 (x64) was an update released in August 2020. This version focused primarily on adding support for new cameras and lenses, as well as fixing several performance bugs reported in previous iterations of the 9.x cycle. Key Details of Version 9.4 Release Date: August 2020. Architecture: 64-bit (x64) for Windows and macOS. Primary Focus: Stability and hardware compatibility. Notable Features & Improvements
New Camera Support: Added raw file support for then-new models like the Nikon Z 5, Olympus OM-D E-M10 Mark IV, and various Panasonic Lumix models. Unlike major annual releases (v10, v11), point releases

If you have a valid license & installer file (.exe for Windows x64): Adobe Photoshop Lightroom Classic 9
⚠️ This version has no native Apple M1 support – it runs via Rosetta 2 on Mac. But you asked for x64, so I assume Windows.
Lightroom Classic 9.4.0.10 fully utilized OpenCL acceleration on compatible GPUs. Users with mid-range NVIDIA GTX 1060 or higher and AMD Radeon RX 500 series saw a noticeable speed boost in the Develop module’s brush adjustments and gradient filters.
Adobe’s naming convention for Lightroom can be confusing. Lightroom Classic (version 9.x) represents the traditional, desktop-focused, file-based workflow, as opposed to the cloud-centric “Lightroom” (formerly Lightroom CC). Version 9.4.0.10 (64-bit) was released in August 2020 as a minor but impactful update to the 9.x series.
This version arrived at a unique time—mid-pandemic—when photographers were relying heavily on remote workflows, tethering, and efficient local editing. While newer versions (v10, v11, v12, and v13) have since introduced masking upgrades, AI-powered denoise, and content-aware remove, 9.4.0.10 holds a special place for users who prefer a mature, bug-fixed release without subscription nagging or hardware acceleration issues.
