app-cardano VS cardano-multiplatform-lib

If this isn't the right forum to raise this issue, please guide me where I may. I believe main code for this app lives [here](https://github.com/LedgerHQ/app-cardano), but I seemingly can't raise an issue there.

I think you are correct, it looks like it's a public repo that can be contributed to here: https://github.com/LedgerHQ/app-cardano

Check the tags for your device here: https://github.com/LedgerHQ/app-cardano/tags

No, unless the changelog is outdated

Also here is the ledger GitHub of the Cardano App: https://github.com/LedgerHQ/app-cardano/blob/master/src/keyDerivation.c

EDIT: Would https://github.com/LedgerHQ/app-cardano be the right place?

You can see this in the repositories also: https://github.com/LedgerHQ/app-cardano/releases

The Ledger's Cardano App is open source and available on GitHub: https://github.com/LedgerHQ/app-cardano

One more thing that I can add. The outputs in my transaction are all in post alonzo format (https://github.com/input-output-hk/cardano-ledger/blob/e31573a166f2b183b69653138863a0bd23c97fd6/eras/babbage/test-suite/cddl-files/babbage.cddl#L87-L92) if I deserialize my transaction using Cardano Multiplatform Library (https://github.com/dcSpark/cardano-multiplatform-lib) and serialize it back, I end up with slightly different CBOR (see https://pastebin.com/JJ5xLpz9 ) where outputs which could be simplified to alonzo format, got simplified into it. This transaction has id: "19316b763e9f1093b58dd8c33f6a5929137ffc40d9a64da3a7da96276215bb5a" and I am successfully able to sign it. But shouldn't I be able to sign the original transaction too? This is adding complication of using CML which is something we aren't willing to do and also it results in different transaction hash than what we would expect.

This is part of a larger initiative we've called Cardano Multiplatform Lib - a project to create cross-platform SDKs for various parts of the Cardano stack You can find the CIP25 CML codebase here
