Version 19.2

September 18, 2019

New General Features

  • Supported AVX-512 and SHA instruction sets found in recent CPUs (64-bit only).

  • Improved the speed by dividing the core program into 3 executable files -- ee512.exe for AVX-512, ee256.exe for AVX-2, and ee128.exe for SSE2 instruction sets (64-bit only). EmEditor automatically selects the most optimized executable file by default, or a user can select any executable file as long as the current CPU supports the corresponding instruction set.

  • The new version displays more error information during Find in Files and Replace in Files if any files are skipped from search due to errors.

  • The new version displays the number of matches or strings replaced in the status bar after Find in Files and Replace in Files.

  • Greatly improved the speed of opening very large files, Delete Duplicate Lines, Find in Files, Replace in Files, and various Sort commands.
