I've already adapted FFI APIs but not released anything yet. There are still a some things to rework before the next release. I think if you fork the repo, you should be able to run the workflow for building them by yourself: Fork the repo -> Go to "Actions" -> Select the "Publish" workflow -> Click on "Run workflow" -> Select the commit to use, deselect everything except "Build KMP" (the "Swift package version" can be empty) and DON'T select "Publish" -> Run it and you'll find the AAR in the artifacts (called nostr-sdk-ffi-kmp-aar). Compilation can be done also locally, but unfortunately requires macos as it needs binaries also for iOS, and I didn't found a way to cross-compile them from Linux. https://github.com/rust-nostr/nostr-sdk-ffi/commit/72c07c61b460c701dcfc93d51bc83e4a1c5eb689
