Happy New Year everyone!!
We are very close to release Blink 15, that will bring major changes (check our Twitter). But we did not want to hold some other cool new features and major fixes. Enjoy!

- We made big changes to our SSH Configuration.
- You can now define per Host SSH Configuration settings, like ForwardAgent, for those details that do not have a UI interface.
- We also added support for ForwardTunnel and RemoteTunnels in the configuration, so you do not have to define them at the CLI anymore. Just set them there, and all the tunnels will be started with every connection.

- FileProvider directory create and item rename
- FileProvider item rename and deletion
- FileProvider can now extract zip and archives to the remote.
- FileProvider issues traversing paths with accents. Fixes #1321

- SSHClient uses the server SHA fingerprint format for host key, as it is the standard.
- SFTP fixes when copying zero or unknown size files.
- SSH fixes. 2FA on a corner case authentication.
- HostKey acceptance issues (#1296)
- Window state fixes to keep format properly.
- Fix known_hosts key format in ssh2 command. Fixes #1296
- history command outputs 500 lines by default. Added -a flag to list all history. Refs #1187
- Support user names with @. Fixes #1303
- Fira Code 6
- Better placeholder for HostName
- Mosh alias --no-ssh-pty to T.
- Fixed a crash when the logger could not write to the logging file while on background.
- SW and HW Keyboard fixes.
- Lots of fixes and crashes from TF, check out our commit logs for more information.

New on this version is the new Files.app integration inside Blink, to give you easier access to your remote files, kinda like interactive SFTP, the iOS way. Sometimes, touches are better than commands. You can enable it inside Settings > Hosts by flipping the Files.app switch on the Hosts you wanna access. It also makes them easily accessible by other apps, so for example, you can attach a file from your server to an email, without typing a single command.

Few bug and stability fixes as well:
- 2FA fixes for a strange case where a public key may be followed by a password and 2FA.
- Fixed terminal display modes and other flags being reset after some time.
- Changes on state reset.

- Safer migration flow to new file structure
- Added iPad mini 6 support

- Fix 2FA authentication flows over ssh. Thanks for the heads up to @ariejoost and Himanshu Chauhan.

SSH
To get the ball rolling, we are releasing a new SSH subsystem. This will allow us to make a few key improvements and to tailor new services inside our app.
- New SSH connections are automatically ran from a pool. This will allow you to start tunnels on top of running sessions and all those. If you want to run separate connections, you can use -o ControlMaster no.
- We now support ProxyJump flag (-J) to simplify setting up ProxyCommand.
- Improved argument parser, verbose output and error communication.

Tunneling
- Tunnels have been completely rewritten.
- Tunnels can now be started on top of existing connections without depending on running interactive sessions. You can do that with the -N flag.
- You can control running tunnels with the -O stop|start setting.
- Reverse tunnels now support port 0 (as in -R 0:localhost:XXX), so that the remote server can assign and send a port back to the client. This is useful for ngrok and other tools where you can now do `ssh -R 0:localhost:8080 tunnel.us.ngrok.com http`.

SOCKS5 Proxy (#1234)
- Blink can now do Dynamic port forwarding, aka SOCKS5 proxy or server. This is perfect as a simple VPN that allows you to browse the internet using a remote machine as a proxy, or - a more critical dev scenario - to access backend services behind a Firewall. As a SOCKS proxy sits at layer 5 of the OSI stack, its performance is also astounding, try for yourself! For more information, please read #1234

New Agent built-in and and Keys
- More secure Blink Agent built in. First we improved the integration, so there is no need to start it separately anymore. You can add keys to the agent by using ssh-add (-d to remove). The Agent can be forwarded by using the standard ssh -A.
- The Agent will now handle all key needs for the user, giving better feedback.

Support for Certificates (#653)
- You can attach a certificate to a key and use it for Login. Certificates are a safer way to handle teams of users or fleets of devices. Please note the CA will have to sign the public key (as part of the certificate generation process) separately. For instructions please read: https://gravitational.com/blog/how-to-ssh-properly/

Secure Enclave Keys (#457)
- Blink can now create Secure Enclave Keys. “The Secure Enclave is a hardware-based key manager that’s isolated from the main processor to provide an extra layer of security. When you store a private key in the Secure Enclave, you never actually handle the key, making it difficult for the key to become compromised.”

New architecture for Keys
- We have rebuilt our Keys architecture on top of OpenSSH. We were having a lot of issues with the mismatch between OpenSSH and LibSSH, so now everything is done the standard OpenSSH way.
New interface for Key Management
- To wrap it all up, we bumped our keys UI to offer the new options in a cleaner way and with an improved ssh key import flow.

SFTP - SCP
We have new SFTP/SCP commands, implemented from scratch on top SFTP, with a SCP style interface. It is faster than anything on iOS, and even faster than OpenSSH SFTP command!
- Support for wildcards, recursion and three way copy: user@host1:file user@host2:destination_path. Because nothing is stored locally, it is very fast!
- SFTP and SCP capture port using the hash: user@host1#port:file
- Rsync style update with --update. It will traverse the whole hierarchy, checking for changes and only uploading when there were modifications to a file!
- Preserve permissions.

Mosh
- Improved Mosh and other command outputs.
- New Flags supported.
- Improved Mosh durability

iOS15 and other goodies
- Facecam command
- We reworked the directory structure of our container.
- New menus.
- Notifications. Bell notifications and sequences.
- Fixes on configurations and making sure everything is still in place.
- Updates for new devices
- Many many bug fixes
- Libraries updated
- And many more things!

A few app tune-ins before we release our next major version, to make sure everyone is in shape for the upcoming news:
- Make sure configuration file permissions are accessible when app may be running in the background.
- Tune keyboard behavior for QuickType bar.

- Pragmata now displaying dev characters. Now including Full PRO font!
- Fixed SSH Connections not displaying Unicode characters properly. Pass defined locale to remote ssh connections through LANG variable.
- Fixed Emacs not opening files on arguments. Required to fix OSC 10.11 responses for background colors.

Version 13.5.7

- Fixed keyboard appearance style

Version 13.5.6

Improved mosh restore (#1048). When closing the Smart Keyboard while Blink is open, we found there was a case when the state storage and screenshot activation would collide and invalidate the previous state, so Mosh would not recover. We fixed that and we are back to rock solid again.

Version 13.5.5

- Restored iCloud sync
- Fixes for new op system. #1071, #1065, #1056, #1055, #1053, #1049
- Blink now opens ssh:// links
- SSH keys import from Files.app. #1057
- Restored x-callback-url, #827

Disabled iCloud support temporarily. If you need iCloud support, please do not update. We are trying to go through a transfer process and unfortunately the requirements are not the best. We apologize for the inconvenience.

Version 13.5.2

- Fixed 3f menu for improved compatibility. #1049
- Updated JetBrainsMono font to v2.3.
- Allow to remap more keys on German keyboards.

Emacs users rejoice, Ctrl-space is back!

To configure it, go to keyboard configuration, Custom Presses, type Ctrl-space and assign it to Ctrl-space. Note that you can also assign the same Carl-space sequence to any other key combination.

Enjoy!

Nothing out of the normal here, just your favorite app getting better ;)
