uSync.Migrations ships one release line per Umbraco major, matching the uSync release it plugs into. Fixes go to the current line, and to the previous one where the issue is serious and the fix is practical.

Please do not open a public issue for a security problem.

Email kevin@jumoo.co.uk with a description of the issue, the version affected, and steps to reproduce it. We'll acknowledge within a few working days and keep you updated as we work on it.

uSync.Migrations reads and writes uSync files on disk as part of a migration, so if the issue involves file paths, archive extraction, or parsing of a supplied uSync export, say so — those get sequenced first.
