2026-10-26 00:07:20 +00:00 | 0 commits to main since this releaseFlowState 1.5.2: the 1.5 release with the maintenance fixes from 1.5.1 and 1.5.2.
FlowState 1.5 follows 1.0.0 directly (there was no 1.1). Highlights:
- SuperPro Designer v15 parity: the new v15 unit procedures, operation options, resources and costing, and an
.spfimporter for v10–v15 files (all 194 SuperPro v15 examples import). - Plain-language names for every unit procedure and operation; search still finds the old names.
- A COMSOL-inspired interface: Model tree, Settings pane with the model equations, contextual toolbar ("ribbon-lite"), bottom dock, line-art PFD drawing style and an illustrated icon family.
- AI and automation: an MCP server for AI agents, reviewable changesets for every AI or API edit, and an in-app assistant with the provider of your choice (offline by default).
- Analysis: study engine v2, TEA presets (NREL DCFROR, MACRS, IRR / minimum selling price), a scenario workspace, quick GWP and LCA additions, parameter estimation with D-optimal design, stiff dynamics with rigorous batch distillation, site fit and recipe scaling, and an ISA-88 recipe text view.
Existing
.flowfiles open unchanged and give the same results; new data is left out of files while unused. Test, benchmark and import results are indocs/release/1.5-validation.md.Fixes since 1.5.0
- File dialogs no longer freeze the window, and there is a fallback when the system file dialog does not respond.
- Symbols display correctly on Linux and macOS.
- Slow exports run in the background, and typing in large models is smoother.
- Scenario waterfall, comparison table and section frames have been improved.
