New releases of Asterisk will be made roughly once a year, alternating between standard and LTS releases. Within a given release series that is fully supported, bug fix updates are provided roughly every 4 to 6 weeks. For a release series that is receiving only maintenance for security fixes, updates are made on an as needed basis.
