MailStore like to share an important information regarding the upcoming release of MailStore version 25.1 on January 8, 2025, which requires all MailStore users to take action now.

In MailStore version 25.1, there will no longer be support for databases running with the Firebird 3 or Firebird 2.5 database management system. This affects both the master database, which contains the configuration data, and the internal archive stores for email data. This means that MailStore users must update their databases to Firebird 4 to be able to use MailStore version 25.1 in January.

If the databases are not updated to Firebird 4 before installing MailStore version 25.1, databases can no longer be loaded in MailStore version 25.1. This means that the email archive cannot be opened and used.

We recommend installing MailStore version 24.4 before switching to MailStore version 25.1. This allows the databases to be updated to Firebird 4. In January, you can then easily switch to MailStore version 25.1 (available from January 8, 2025).

If MailStore version 24.4 is already installed and the databases (both the master database, which contains your configuration data, and the internal archive stores for email data) are running on Firebird 4, there is currently no need for action.

You can find out why updating the installation and databases is essential and what steps MailStore users need to take now in our official communication including FAQs.
