ShorePowerCalc version history

Current release

Current release

Optional Branded Reports add-on

• Adds support for the separately licensed Branded Reports add-on, including company details, logo upload, ready-made palettes, custom report colors, and a live color-location guide.
• Accepts PNG and JPEG logos up to 5 MB, trims transparent padding, and fits wide, square, or tall artwork proportionally without cropping or stretching.
• Applies customer identity only to supported PDF presentation and metadata while keeping the application, installer, calculations, technical notes, warnings, and version information under ShorePowerCalc.
• Allows users to switch between customer-branded output and standard ShorePowerCalc reports.

Release integrity and documentation

• Improves license integrity, PDF export safeguards, and packaged-release verification.
• Expands the illustrated user guide to 37 pages with Branded Reports setup and activation instructions.
• Verifies the release through 207 calculation regression checks, 216 supplemental calculation cases with 875 assertions, a 2,514-scenario full-application audit, and independent PDF QA covering 267 generated pages and 140 tables.
• Includes packaged security review and separate live Gumroad activation testing for the base product and add-on licenses.

Previous release

Version 2.1.3

Calculation and equipment validation

• Adds a 2026 Design BE/CE five-second locked-rotor conductor screen for applicable three-phase boat-lift motors and carries required thermal upsizing through proportional EGC treatment.
• Corrects same-slip boat-lift feeder reconciliation and preserves exact whole-lift simultaneous-operation selection with independent worst-case phase-current checks.
• Corrects general THWN-2 calculations to start correction and adjustment from 90 C insulation ampacity and cap the final result at the assumed 75 C equipment termination.
• Restricts Type G and Type G-GC calculations to supported copper manufacturer constructions; unsupported saved materials remain visible and block calculation until corrected.
• Strengthens center-tapped transformer sizing, phase balancing, breaker-table limits, and shared 208V three-phase boat-lift voltage drop.

Reports and packaged-build integrity

• Embeds report fonts and bounds dense header, footer, and image placements to prevent renderer-dependent PDF clipping.
• Includes clearer conductor-upsize markers, breaker labels, and a dedicated Large Marina transformer-sizing schedule.
• Adds release gates for packaged-source parity, conductor scenarios, purchaser-file allowlists, checksum verification, and exact executable attestation.

Project reliability and activation

• Autosaves an established project when workflow tabs change and presents Save, Don't Save, and Cancel choices when closing changed work.
• Reliably delivers double-clicked or command-line .mlc projects after application startup.
• Uses the Windows Chromium network path for Gumroad activation so system proxy, authenticated proxy, and enterprise certificate settings are honored with strict HTTPS validation.

Release verification

• Verified 166 calculation and interface regressions before packaging.
• Completed 897 full application, responsive-layout, one-line, and PDF scenarios across Single Panel, Multi Panel, Large Marina, boat-lift, other-load, and edge-case projects.

V2.1 foundation

Version 2.1.0

Version 2.1.0 introduced the seven-step Project-to-One-Line workflow, Other Marina Loads, Prepared For and Prepared By metadata, serving-equipment selectors, reorganized Results, tagged vertical one-lines, and the rebuilt standard PDF report engine. It also expanded boat-lift voltage, conductor, raceway, and actual OCPD planning across all three project modes.

Previous release

Version 2.0.0

Version 2.0.0 introduced the Single Panel, Multi Panel, and Large MDP & Substation project modes, selectable 2023 and 2026 demand-calculation bases, expanded boat-lift motor workflows, feeder and phase-loading results, combined reports, Gumroad activation, EULA acceptance, and the current 365-day customer license model.

Previous public line

Version 1.2.8

Version 1.2.8 was the previous single-panel public release. It supported the original marina panel, pedestal circuit, schedule, one-line, project-save, and PDF workflow.
