# Keeper Gateway 1.7.4

Keeper Gateway 1.7.4 delivers major improvements in stability and performance for Keeper Connections and Discovery, along with additional feature enhancements and bug fixes.

### Improvements

* Major performance and stability improvements with Keeper Connections and Discovery
* **PG-60:** Added a Linux folder build specification to support gateway deployments in locked-down environments without `/tmp` access
* **DR-949:** Added password propagation to IIS Application Pool log-on credentials. Detection of the log-on credentials is automatically picked up and managed by [Keeper Discovery](/keeperpam/privileged-access-manager/password-rotation/service-management.md) or through Keeper Commander's [`pam-action-service-add`](/keeperpam/commander-cli/command-reference/keeperpam-commands.md#service-add) command.
* **PG-77:** Added support for ssh keys requiring passphrases. To connect to a resource using a PAM User record having the SSH private key, you need to simply create a new hidden field called "`Private Key Passphrase`". The name of this field must match exactly.
* **PG-88:** Improved docker installer command
* **DR-1127 & DR-1122:** Optimized discovery graph checking when adding resources and users
* **PG-81:** Added support for RHEL 9 Gateway docker image
* **PG-132:** Gateway now refuses connection if Gateway is overloaded
* **DR-1128:** Improved date parsing in LDAP user search
* **PG-133:** Improved CPU performance on Windows Gateway

### Bug Fixes

* **PG-40:** Fixed issue where Router restart caused windows gateway service to stop
* **DR-1115:** Fixed issue where Rotation fails for Windows local for non admin records
* **PG-89:** Fixed issue with Docker permissions when installing the gateway with the docker installer command
* **PG-91:** Fixed issue where installing hangs on Ubuntu Kerberos installation
* **PG-118:** Fixed issue where Linux Gateway goes offline after repeated interactions
* **PG-125:** Fixed Session Recording delays on Windows Gateway
* **PG-131:** Fixed delays in connection closures
