## 1 SSH Release Notes

This document describes the changes made to the SSH system from version to version. The intention of this document is to list all incompatibilities as well as all enhancements and bugfixes for every release of SSH. Each release of SSH thus constitutes one section in this document. The title of each section is the version number of SSH.

### 1.6 Ssh 0.9.5

#### 1.6.1 Fixed Bugs and Malfunctions

### 1.7 SSH 0.9.4

  Also, more cryptographic algorithms have been added to the `crypto` application.
