Summary

  • Fix dll_name setting (was reading nonexistent pinned_version)
  • Update DLL naming from numeric (0, 2, 5) to codenames (rs2, ni, ge)
  • Correct build ranges per EP wiki:
    • ni: 22621-22635 and 23403-23620 (not 25197)
    • .3 request-only: 25115-25915 (not 25201)
  • Fix memory leak: move install_path allocation after PickTaskbarDll() check
  • Update settings description and README for codename filenames
  • Add comment noting UBR limitation for 22621 < .1343
  • Fail closed for request-only builds (1, 3, 4) with log message

Rationale

The ep_taskbar_releases repo switched from numeric naming to codename naming as of April 2026. The latest release (1d8133a) ships:

  • ep_taskbar.rs2 (Windows 10)
  • ep_taskbar.ni (Windows 11 22H2/23H2)
  • ep_taskbar.ge (Windows 11 24H2+)

Builds requiring ep_taskbar.1, .3, or .4 are listed as "available upon request" in the EP wiki. These versions exist due to ABI differences in ITrayComponentHost across Windows builds. Neither the old numeric releases nor the new codename releases ship these publicly. Users on those builds can obtain the DLL separately and pin it via the dll_name setting.

Build ranges corrected per the EP taskbar wiki: Dev builds 25115+ require .3, not .2/ni.
