+- `arangodb` versions 3.3, 3.4, and 3.5 have been removed because they are at EOL upstream. The default is now 3.10.0. Support for aarch64-linux has been removed since the target cannot be built reproducibly. By default `arangodb` is now built for the `haswell` architecture. If you wish to build for a different architecture, you may override the `targetArchitecture` argument with a value from [this list supported upstream](https://github.com/arangodb/arangodb/blob/207ec6937e41a46e10aea34953879341f0606841/cmake/OptimizeForArchitecture.cmake#L594). Some architecture specific optimizations are also conditionally enabled. You may alter this behavior by overriding the `asmOptimizations` parameter. You may also add additional architecture support by adding more `-DHAS_XYZ` flags to `cmakeFlags` via `overrideAttrs`.
 
 - The `meta.mainProgram` attribute of packages in `wineWowPackages` now defaults to `"wine64"`.
