Added the 8-Bit ALU (Arithmetic Logic Unit) as a core component, supporting addition, subtraction, AND, and OR operations.

Significantly improved simulation performance for large circuits with over 100 components.

Resolved an issue where wire connections would sometimes misalign after dragging a component.

Introduced custom components (sub-circuits) for Pro users. You can now encapsulate a circuit and reuse it as a single block in other designs.

Launched our new documentation pages to better support our users.

Redesigned the main component toolbar for a cleaner look and more intuitive grouping of components.

Fixed a bug that caused the Clock component to occasionally skip a pulse at high frequencies.

Added the 8-bit Register and Tri-State Buffer components, essential for building computer memory systems.

Users can now add labels to any component to better document their circuits.

Corrected the output behavior of the XNOR gate which was inverted in some cases.

Introduced the 4-bit Adder component for arithmetic operations in digital circuits.

Enhanced the wire routing algorithm to prevent overlapping connections.

Fixed simulation freezing issues when using multiple clock sources.

Added support for multi-bit buses to handle complex data paths.

Improved the user interface with better component icons and tooltip descriptions.

Resolved memory leaks that occurred during long simulation sessions.
