## Body
E2B releases published e2b@2.59.0. This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: Minor Changes e5a9fa6 : Add dnsServers to the network options ( dns servers in Python): the DNS servers a sandbox can reach when allowOut contains a domain. Leave it out to allow the default, 8.8.8.8, pass a list of IPs to allow those instead, or pass to allow none. It only opens the firewall and doesn't change the sandbox's /etc/resolv.conf . updateNetwork / update network reset it to the default when it is left out, like the other fields, and getInfo / get info report it when set. Patch Changes 5a714f0 : Deprecate the apiUrl / api url and sandboxUrl / sandbox url connection options and their E2B API URL and E2B SANDBOX URL environment variables. They keep working for now and will be removed in the next major version. 61b6b55 : Use the unified https://sandbox. endpoint for sandbox traffic on e2b-tango.dev , e2b-juliett.dev and foxtrot-2.e2b.dev .
