Komodo Wallet v0.9.0 Release

We are excited to announce Komodo Wallet v0.9.0. This release introduces HD wallet functionality, cross-platform fiat on-ramp improvements, a new feedback provider, and numerous bug fixes and dependency upgrades.

Under the hood, the app has undergone a major rewrite to migrate to our new KDF Flutter SDK. This allows developers to quickly and easily build their own DeFi applications in hours instead of months. See the SDK package for more information.

The codebase is now unified across all web, desktop, and mobile platforms. This change allows for more consistent development and easier maintenance.

TODO

KDF SDK

This app migrates most of our codebase to the new KDF Flutter SDK, which showcases how even hobbyist developers can build their own GUI apps using our simple tools and avoiding the months of headache and time invested in starting from scratch.

Due to this dual benefit, we appreciate your patience with any teething issues or regressions of existing features.

QA

cc @KomodoPlatform/qa

While HD support is the most notable user-facing change, this is an entire rewrite "under the hood", so all features are affected. Please test widely. The follow-up release will focus on any major issues identified after release as well as general performance optimisations (especially those which have regressed since pre-SDK migration).

Please also note that any issues already reported which are not patched will be addressed in a future update.

Auto-reviews:

NB: The CodeRabbit summary below is incomplete and only considers the incremental changes between the commit when the branch was updated and the current commit because it exceeded the max length when opening the PR. In the future, we will always keep a PR open for dev->main to avoid this limit.
