itemis SECURE 26.1!

We are excited to announce itemis SECURE Classic 26.1, a release that continues our focus
on improving collaboration, strengthening core platform foundations, and enhancing
day-to-day usability and workflow reliability. This version introduces important advances in
cross-product collaboration with SECURE Cloud, delivers a major platform upgrade to ensure
long-term security and runtime alignment, and includes targeted improvements that make
modeling workflows more robust, transparent, and predictable.

In this release, we enhance cross-product collaboration in SECURE Classic by improving the
stability and consistency of shared workflows with SECURE Cloud. A key addition is support
for centrally managed threat catalogs for TARAs, enabling reusable security content and
consistent access to catalog updates across models. Alongside this, synchronization and
update processes have been improved for greater reliability and control in collaborative
scenarios.

With this release, we have further strengthened the SECURE Classic platform through a major
platform upgrade, aligning the system with current runtime expectations, addressing key
security requirements, resolving underlying vulnerabilities, and introducing selected usability
improvements as part of ongoing modernization efforts.
Finally, we improve the handling of broken references in models by providing clearer control
over unresolved links in cases where referenced elements are no longer available. In addition
to existing automatic recovery behavior, users can now explicitly remove dangling references
when they are no longer needed, improving transparency and control in model maintenance
scenarios.

Looking forward, we remain committed to continuously advancing itemis SECURE Classic
along three key directions: foundational work towards IEC 62443 support, further expanding
cross-product collaboration between desktop and web environments, and continuing the
systematic migration of the platform to modern technologies. These efforts reflect our
ongoing focus on strengthening interoperability, improving usability, and ensuring the
long-term evolution of the platform.
