# Bug fixes, improvements
* Large effort to address DNS configuration issues and Magic DNS on all platforms.
* allow client access to exit node's public IPs
* Tailscale up command now warns when options are being changed by omission. For example if one had used `tailscale up --advertise-route=192.168.0.0/24` and then uses `tailscale up --advertise-exit-node` it will notice and warn that the advertise-route would be removed.
* Support SCTP in port-based ACLs, in addition to TCP and UDP
* In magicsock if IPv4 and IPv6 have similar latency, prefer IPv6
* Add `tailscale ping -tsmp w.x.y.z`, which sends a ping at a layer which doesnt involve the host IP stack. Only destinations running 1.8+ will respond.
* Add add `tailscale ip [-4] [-6]` command, suitable for use in shell scripts to retrieve the Tailscale IP addresses.
* add `tailscale bugreport` command to log a timestamp, use shortly after a problem occurs to make it easier for support@tailscale.com to find. Note that you do still need to send email or file a bug, the bugreport here just adds a known point in the logs.
* Add `tailscale logout` command
* When run with `--tun=userspace-networking --socks5-server=...` tailscaled can now be a SOCKS5 proxy for all addresses not just Tailscale addresses.
* fix `tailscale status --json` AuthURL field
# Platform-specific
## Linux
* Much better support for DNS server configuration and Magic DNS in Linux distributions using systemd-resolved, NetworkManager, and resolvconf: https://tailscale.com/blog/sisyphean-dns-client-linux/
## Windows
* Behavior change: ForceDaemon now off by default, use “tailscale up --unattended” to get previous behavior
* Windows systems can now serve as subnet routers and exit nodes. cmd.exe must be used to enable this: `tailscale up --advertise-exit-node` or `tailscale up --advertise-route=192.168.1.0/24`
* Dont logout when Windows GUI disconnects
## MacOS
* MacOS systems can now serve as subnet routers and exit nodes using https://github.com/tailscale/tailscale/wiki/Tailscaled-on-macOS
* Fixed MacOS Big Sur DNS behavior when using an exit node
* https://github.com/tailscale/tailscale/issues/1647
* TODO(dgentry) - is LAN access changing?
## Synology
* Synology systems can now serve as subnet routers and exit nodes.
# dgentry notes:
* Not mentioning file transfer, will be in early access for a while
* Not mentioning Split DNS, will introduce post 1.8.0
* not mentioning Cloud Run, want ephemeral keys to be available first
