## 1 SSH Release Notes History

### 1.1 Ssh 0.9.9.6

#### 1.1.1 Improvements and New Features

- Updated asn1 file due to change in the asn1 compiler. This has no semantical effect on the ssh application.
  Own Id: OTP-7246
- Allows for the option {fd, FD} in listen and connect calls. The option is passed on to gen_tcp:listen and gen_tcp:connect
  Own Id: OTP-7247

### 1.2 Ssh 0.9.9.5

#### 1.2.1 Fixed Bugs and Malfunctions

- Putty version 0.60 sends ignore messages, which hanged the OTP ssh server.
  Own Id: OTP-7076
- ssh_cm hanged when connection was closed during handshake. (Triggered by putty 0.60 client.)
  Own Id: OTP-7089

  Own Id: OTP-7135

#### 1.2.2 Improvements and New Features

- Now uses the base 64 encode/decode function in stdlib.
  Own Id: OTP-6486

  Own Id: OTP-6570
- Documentation update of ssh.
  Own Id: OTP-7063 Aux Id: seq10789

  Own Id: OTP-7090 Aux Id: seq10675
- Kebord-interactive support, according to rfc 4256, has been added to the ssh client. Also the option quiet_mode has been added so that unwanted banners may be suppressed.

  Own Id: OTP-6854 Aux Id: seq10740

  Own Id: OTP-6458
