At MDB, we are dedicated to providing our users with cutting-edge tools for web development. As the industry continues to evolve, so must the frameworks and technologies we employ. In line with this progress, we are transitioning MDB4, our previous version based on Bootstrap 4, into a legacy version, and encouraging our users to migrate to MDB5. This article aims to explain the reasons behind this transition and offer guidance to ensure a seamless migration process.

User Satisfaction and Adoption

We are thrilled to announce that a significant majority, over 80% of free users, and over 90% of customers already use the latest MDB5 version. We also notice that users that migrated from MDB4 to MDB5 expressed higher satisfaction with the new version. Their positive feedback and success stories reinforce our belief in the enhanced capabilities and better experience offered by MDB5.

Moving Forward with Web Development standards

In the ever-evolving world of web development, frameworks play a pivotal role in staying up-to-date. As Bootstrap 4 officially ended its support on the 1st of January 2023 , the industry has shifted towards integrating Bootstrap 5 with modern frameworks. To align with the latest industry standards, we strongly recommend our users embrace MDB5 for compatibility and leverage its advanced features, integration possibilities, and and optimizations.

Continued Updates for MDB4

Despite the release of MDB5, we have diligently maintained and updated MDB4 for over two years, demonstrating our commitment to supporting our users. However, as we shift our focus to the future of web development, we have made the decision to classify MDB4 as a legacy version, allowing us to concentrate our resources on enhancing MDB5 further.

Low demand for MDB4 updates

A study by Cloudflare reveals that JavaScript libraries are rarely updated once installed. While MDB4 remains a highly efficient and mature toolkit, it is unlikely to need significant updates or improvements moving forward. The older the project is, the less likely it is to update its dependencies. There is simply very little demand for updating MDB4 and keeping it integrated with the latest modern tools.

Maturity of the legacy version

MDB4 is still a robust and capable toolkit, and we encourage users to continue utilizing it in projects where it is already installed. It remains a reliable option for those seeking stability and maturity in their web development endeavors.

Support and Assistance

We understand that transitioning to a new version can pose challenges. Although MDB4 will become a legacy version, we are committed to providing professional technical support for 12 months after this transition. We will keep answering your questions, and help you figure out the practices and standards we employed in MDB4, However, it is important to note that no new feature requests will be taken on for MDB4 moving forward, and no future updates will be released.

Migration Assistance

We understand that project migration can be a complex endeavor. MDB5 was written from scratch. Literally every line of code has been rewritten to ensure the highest possible quality. The changes are very significant and in many cases it was not possible to maintain backward compatibility. We chose the right quality over backward compatibility and it was a deliberate decision. Whenever possible, we recommend that you create your project from scratch in MDB5, instead of updating old MDB4 projects to MDB5. While technical support will not cover migration assistance, we are here to help. If you require professional migration services, please reach out to us via the form below, and our dedicated team will be ready to assist you.
