# v77 — More intelligence ![](https://lh7-qw.googleusercontent.com/docsz/AD_4nXdfcNVj5MARnW9Mz-s_4hi8IAhJnbMLq5D6csBh7AxAPNi3OJqi6pDXYfpvUxph23RHPRDspFNjTLAvs9uGfQ7OZlJQZ47dXsRfO2ArOaRV_DiDau_siRKvPsiEuR_0NbTKtIbzmasxIFdrWYbvFKBsLxiO?key=chRXiLUrI54Os_fCIQ1Z3w) ## Features * Added “Artificial Intelligence” Agent, providing a conversational chat interface and an initial RAG AI implementation * Largely extended App Builders’s linkage highlighting. Highlighting in general works in all directions and across backend and frontend. Input items can now receive data from multiple (and even mixed) sources. * Data updates are now visible via animated item logos of the corresponding executors. * Low-Code functions can be commented * Better UX support for large input objects * Automatic full-app snapshotting (backup) for each new deployed version ## Fixes * Snaplines are largely fixed. They react only on visible widgets and appear during resizing as well. Widgets can be resized in a 10px grid only, making it easier to align them. * Mobile and tablet screen scalings on production apps are fixed and the performance got optimized * Several fixes in SensorThings API Connector * App Installation message shows only on platforms that support PWAs * Entirely removed buggy undo/redo functionality --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
