As Anyquery is in active development and not yet in a stable release, don't expect any LTS versions. The only supported version is the last one, and users are expected to update their software to the latest version.
To report a vulnerability, please send an email to contact@anyquery.dev. Never open an issue for it.
Please don't expect any bounty as Anyquery has an annual budget of $10 (for the domain name). I would love to provide some but Anyquery is a small open-source project without any funding.
