    - Additional fixes related to the new disaster weather information system - Fixed an issue where typhoons would sometimes not render in the “National” home screen tab - Updated the Privacy Policy We would like to apologise for the concern caused by the development team update in our previous release notes. We received many messages of support and concern from users and other organisations, and were even contacted by members of the National Diet and the Japan Meteorological Agency asking if there was anything they could do to help. Though we can’t go into too much detail out of consideration for our relationships with other organisations, we have maintained regular communication with the Japan Meteorological Agency throughout both the lead-up to and rollout of the new disaster weather information system. More recently, we also visited the JMA headquarters for an in-person meeting to exchange views and share information, and have submitted requests for further improvements. Now that the work surrounding the new disaster weather information system has settled down, the development team has once again started work on new features! We’re excited to get them to you as soon as possible, so please bear with us for a little longer. Thank you for always supporting the NERV Disaster Prevention app.

    * Added support for the new disaster weather information system The development team has been working around the clock for weeks to implement this major overhaul of our disaster weather warnings and advisories systems. We deeply sympathise with the Japan Meteorological Agency and the many disaster prevention organisations that are also working through large-scale system changes. Because these changes affect long-standing operational and technical infrastructure, many organisations across the country are facing significant adaptation costs, including system upgrades and revisions to operational procedures. Even just before launch, the Japan Meteorological Agency continues to revise municipal support tables and sample messages, leaving little time for integration testing or trial operations before the system goes live. As a result, there may be unforeseen issues during the initial rollout. Please be mindful that there may still be bugs or issues in the NERV Disaster Prevention app while we work through this transition. During this year’s flood season, we encourage everyone to avoid relying solely on disaster weather information and to use their own judgment to stay safe above all else. Please also take care in the heat.
