After 112 commits coming from 6 different contributors, we are excited to announce the release of BasicSwap version 0.14.2, along with an update to its user interface, now at version 3.1.

This substantial update represents weeks of dedicated effort, incorporating numerous improvements, bug fixes, and new features. The changes stem from extensive testing by both contributors and community members, resulting in a significant step forward for user experience and platform stability.

This update welcomes Bitcoin Cash and implements several key improvements across all aspects of the platform, including changes to the codebase, the user interface, and to individual coin integrations such as Monero.

Notably, a key technical change is the complete replacement of SQLAlchemy with manbearpigSQL, our custom-built hybrid database system. This transition simplifies BasicSwap's data management processes while solidifying security by eliminating potential vulnerabilities

We extend special thanks to Ofrnxmr, Mbacoinin, and mainnet_pat for their code contributions this month, as well as to our dedicated community members who have helped identify bugs and areas for improvement through thorough testing and feedback. This update would not have been possible without their valuable efforts and support!

For a comprehensive list of all changes, please refer to the final section of this blog post.
