+Once software has reached the "Maintenance End" period, it will only receive critical security fixes until the End-of-Life (EOL) date.
 After EOL, users must upgrade to a later version to receive security updates, even though the community may provide fixes for critical issues on a best effort basis.
 Generally, it is recommended to run the latest maintenance release (point release) of the current or previous major version.
 
 Please note that minor versions get bugfixes, translation updates, and soft forks. Translation on [Transifex][bitcoin-transifex-link] is only open for the last two major releases.
