v3.0.0-alpha.1

This release brings significant internal changes that improve overall performance and enable better code reuse. Due to the complex refactoring involved, several features are currently missing and will be reimplemented before the stable release of v3:

• Data relocation diffing
• Displaying data values from instruction tooltips
• Displaying data pool references
• JSON output for objdiff-cli diff
• PowerPC extab display/diffing

If you'd like these features, please continue using the latest stable v2 release until they return.

All object and architecture backends have been completely reworked. Please submit issues for any regressions. Going forward, integration tests are being added to prevent future regressions.

The WebAssembly API was rebuilt on top of the WebAssembly Component Model, and the new internal architecture significantly reduces the amount of data that needs to pass through the WASM/JS boundary. An updated version of the experimental VS Code extension will be released soon with significantly improved performance thanks to these changes.
