Release 26.1 (Q2 2026)

• Feature: Qt-Plugin supports Qt6.8 (Delivered versions for QT and build environment)
• Feature: new AI Coding plugin (chat-assistant integration for the activity editor and class browser):
  • supports both Anthropic Claude and OpenAI ChatGPT as backends, switchable from the settings dialog (Plugins → AI Coding); API keys are stored per provider so you can flip between them without re-entering
  • Toolbar / class-browser menu adapts to the active provider — reads "Ask Claude" or "Ask ChatGPT", updates live when the provider is switched
  • menu actions: Explain code/method, Suggest improvement, Generate test, Generate doc-comment (fills the Documentation tab and pin comments), Find bugs, Custom prompt; "[Apply]" can install proposed code directly into the activity body or compile a proposed helper method into a class
  • chat window streams responses live (Server-Sent Events) and shows running token count + estimated cost in the title; supports image attachments (screenshots / PNG-JPG files)
  • model, API key, endpoint and max-tokens are configurable via the Claude settings dialog

• Feature: improved search text box behavior in text editors (type RETURN, CMD-f or CMD-b while box is open) and back to original position button added.
• Feature: Improved/Fixed Number stack:
  • Enhanced multiprecision numbers (eg. <float>q, <float>Q constants in freeze values)
  • Float32 numbers (<float>f)
  • Integer freezeValues in exponential notation (eg. 1e5)
  • Recognize type specific infinities eg. "inf.0", "inf.0f", "inf.0q" etc. (useful when parsing/receiving values from the outside world)
  • Recognize type specific NaNs eg. "nan.0", "nan.0f", "nan.0q" etc. (useful when parsing/receiving values from the outside world)
  • fixed/added missing trigonometric functions for multiprecision floats and complex numbers (eg. arcTan)
  • inspector (and activitylog as a consequence) show the type of a float (suffix 'f', 'q', 'Q' etc.)

• Feature: Workflow editor — improved orthogonal routing of connections:
  • connections now detour around blocks, freeze values and annotation boxes instead of cutting through them
  • connections from a compound block's input-pin descriptions are bundled into a bus column next to the source pin
  • end-stub avoidance no longer fires on near-misses (strict overlap check, no clearance margin)
  • routing prefers the source-side bend when the source step has multiple sibling pins
• Feature: Workflow editor — improved naïve autolayout: added horizontal and vertical expansion passes that spread adjacent blocks apart for clearer connection routing
• Feature: function to upload/download files from/to remote CBridges (for testData and binaries)
• Performance: execution of elementary Smalltalk and JavaScript actions tuned for speed (Jitter improvements)
• Feature: OLE for 64 bit architectures
• Feature: optional HTTPS for the AIDYMO and license server — drop a PEM cert+key into --workDir (combined server.pem, or splitfullchain.pem+privkey.pem / cert.pem+key.pem) and the service binds TLS automatically; informational hostname is derived from the certificate (SAN-aware, wildcard- and multi-SAN-safe)

• Fix: many fixes related to DPI scaling. I.e. when multiple monitors are configured with different scaling (especially different from 100%). Includes scaling of fonts, bitmap and UI components (widgets).
• Fix: display of very long lines in a text editor/inspector (workaround Windows 16bit line limit)
• Fix: due to a bug in enumeration datatypes, the size of ".ets" files grew over time to huge sizes. This had no effect on the execution, but made load/save times almost unacceptably long by storing/reloading unneeded data.
