Adobe Photoshop Cc 2018 V19.1.1.42094 -x86-x64 -
The Edge Detection brush in Select and Mask received a massive algorithm update between 19.0 and 19.1.1. Build 42094 handles fine hair masking (e.g., a model standing against a forest background) significantly better than any subsequent 2018 update. It uses a proprietary "Decontaminate Colors" engine that doesn't turn stray hair pixels grey.
The release file name indicates "x86-x64."
Even a stable build has quirks. Here is the troubleshooting guide for this specific version: Adobe Photoshop CC 2018 V19.1.1.42094 -x86-x64

In the professional archiving community, v19.1.1.42094 is treated as a Gold Master. Why? Because Adobe later introduced telemetry that could not be disabled. Build 42094 allows you to block adobe-dns.com via your hosts file (127.0.0.1 loopback) without crashing. Issue: Brush lag on high DPI monitors (x64)
Furthermore, the x86 variant is required to run 16-bit Photoshop plugins via a compatibility wrapper (WOW64). No newer version of Photoshop supports this level of legacy hardware integration. If you have a $50,000 Heidelberg drum scanner running on Windows XP mode in VirtualBox, the only native host app that can talk to its TWAIN driver is this specific 32-bit photoshop.exe.
