ACA 2026 Releases

LotSpec for ACA version 2026.1.0

Released: 10/6/2025

Fixes

  • The “Last Solve Time” now correctly reflects when an option set was solved. Previously, it showed a default timestamp of 01/01/01 12:00, even after a successful solve. This fix ensures users can reliably track solve history.
  • Fixed an issue where users encountered publishing errors (Ex: DWF files) when solving lot jobs in ACA 2023 or 2024.
  • Security: Addressed several minor security vulnerabilities for LotSpec for ACA.
