Release status

Windows public beta planned for December 2026

LAMBDA PDF S&E is a Windows desktop engineering PDF and CAD workspace currently in development and release qualification. The public beta is planned for December 2026. The intended first-release scope includes professional PDF editing, CAD-style drawing, calibrated measurement, OCR and technical search, PDF forms, and document-centred collaboration, subject to final qualification.

Context

A release date is only one part of release readiness

A technical desktop application must preserve supported documents and working state, render consistently, protect user information, remain responsive on qualified systems, and install, update, and recover predictably.

The planned date communicates the current target. It is not a claim that qualification is complete, an installer is available, or every described capability is final.

Workflow

How release qualification is progressing

01
Integrate the first-release PDF, drawing, measurement, OCR, forms, collaboration, and document-persistence paths.
02
Validate rendering, security, performance, accessibility, packaging, recovery, and supported Windows behaviour against release criteria.
03
After registration reopens, use controlled early-access feedback to examine representative workflows before public-beta participation is confirmed.

Scope

Intended first-release boundary

Platform

The stated release platform is Windows desktop; qualified x64 requirements will be published before beta access is issued.

Product scope

Professional PDF, CAD-style drawing, engineering measurement, OCR and search, forms, and document-centred collaboration.

Qualification

Integration, persistence, rendering, security, performance, accessibility, packaging, update, and recovery behaviour remain under review.

Who it is for

Engineering and technical teams assessing whether the planned scope matches their work
People tracking when controlled early-access registration will reopen
Reviewers who need a precise boundary between intended capabilities and released behaviour

What the current release message does not promise

The site does not distribute an installer, accept payment, sell a licence, issue an activation key, or guarantee selection for early access.
