Since the previous beta release, I’ve implemented [RetroVault](https://github.com/dirkwhoffmann/retrovault-macos), which uses macFUSE to mount retro disk images (#943). The app relies heavily on existing vAmiga functionality. To avoid code duplication, I refactored and modularized substantial parts of vAmiga so they can be reused more easily in external applications. The latest beta includes these structural improvements. In addition, the following issues have been fixed: #946, #945, #944, #939, and #936.

Changes - Fixed a bug in the CIA sleep logic (#944) - Replaced a toolbar icon (#945) - Added GUI notifications for audio buffer exceptions (#946)

I’m proud to announce that vAmiga is now available as version 3.0! This update introduces run-ahead support (#836), a functionality that had recently been integrated into VirtualC64. When run-ahead is enabled, two emulator instances run side by side: the primary instance and the run-ahead instance. The primary instance emulates the Amiga as usual, while the run-ahead instance runs several frames ahead and generates the image texture. Both emulator instances stay in sync with a time delay, and any changes in the primary instance, e.g., triggered by a joystick event, forces the run-ahead instance to be recreated. Run-ahead mode is meant for gaming as it considerably decreases the lag between an external event, e.g., a gamepad or keyboard event, and its recognition inside the emulator. Accommodating this feature required significant changes to vAmiga’s architecture, resulting in a major update to the codebase. While these improvements have streamlined the internal workings of the emulator, they’ve also introduced some bugs - an expected outcome with such a substantial change. As vAmiga 3.0 is currently in beta, your feedback is crucial to help me refine and stabilize the software. Other enhancements: - Snapshot compression (#840) - Loading and saving memory contents (#823) - Improved Headless app (#839) - RetroShell as as serial port device (#820) - Beamtrap debug feature (#817) - RetroShell commands via the command line (`-""`) Bug fixed: - Fixed a crash when saving a machine state (#833) - Fixed a bug in the CIA sleep logic (#819)

Fixes - The emulator no longer crashes when loading snapshots via the `Open...` menu.

Same as v2.5b1, compiled in release mode.

Licensing: - The emulator core is now licensed under the Mozilla Public License v2 (#802). Enhancements: - A user-definable upper bound limits the size of the snapshot storage. - Denise’s DIW logic is more accurate (#805). Bug fixes: - Fixed a bug related to the allocation of sprite DMA slots (#799). - Fixed a race condition related to the SPRxCTL register (#715). - Fixed an issue with the serial port (9-bit packets) (#803). - Fixed a minor visual issue in the status bar that started showing up with the latest macOS release. Internal changes: - Large data structures are now created on the heap rather than the stack (#811). - In debug builds, debug variables can be switched on and off dynamically in RetroShell.

This version of vAmiga archived the current state of FPU emulation, a work in progress. FPU support will be removed in future releases as the emulator will focus on emulating the three classic Amiga models.

During the last weeks I worked a lot on the code base of vAmiga and VirtualC64. My goal was to align the code bases of both emulators as much as possible, which I managed to do to a large extent. This effort will ease the maintenance of both emulators in future. In the process of refactoring, many internal changes have been made that are not noticeable to the user. However, due to the far-reaching changes, it is likely that one or the other bug has found its way in. For this reason, the new version is released as a beta version first. The biggest change from a user's point of view is the newly added drop layer, which automatically blends in when a media file (ADF, DMS, etc.) is dragged into the emulator. Now changing disks is even simpler than it already was in the old version. Last but not least, the speed of the emulator has been optimized. In warp mode, vAmiga 1.1 runs up to 15% faster than the previous version.
