## Update procedure

To update your installation, perform the following procedure on the Edge nodes:

1. On all Edge nodes:

   1. Clean the Yum repos:

      ```
      sudo yum clean all
      ```
   2. Download the latest Edge 4.18.05 `bootstrap_4.18.05.sh` file to `/tmp/bootstrap_4.18.05.sh`:

      ```
      curl https://software.apigee.com/bootstrap_4.18.05.sh -o /tmp/bootstrap_4.18.05.sh
      ```
   3. Install the Edge 4.18.05 `apigee-service` utility and dependencies:

      ```
      sudo bash /tmp/bootstrap_4.18.05.sh apigeeuser=uName apigeepassword=pWord
      ```

      Where <var translate="no">uName:pWord</var> are the username and password you received from Apigee.
      If you omit <var translate="no">pWord</var>, you will be prompted to enter it.
   4. Update the `apigee-setup` utility:

      ```
      source /etc/profile.d/apigee-service.sh
      ```
2. Run the `update.sh` script for OpenLDAP on all nodes. On each node, execute the following command:

   ```
   /opt/apigee/apigee-setup/bin/update.sh -c ldap -f configFile
   ```

## Bugs fixed

The following table lists the bugs fixed in this release:

| Issue ID | Description |
|---|---|
| 155595660 | **Timezone format** The values used for the `sss` and `SSS` tokens in the timezone format set by the `conf_system_apigee.syslogger.dateFormat` property were not correct. |
| 148486685 | **Indirect bind OpenLDAP replication and SSO interoperability** With indirect binding, the OpenLDAP service was not searching the user object when replication was enabled (there was more than one OpenLDAP instance). |
| 120799182 | **OpenLDAP upgrade** The process for upgrading OpenLDAP in a multi-datacenter environment resulted in a corrupted state. |
| 76087166 | **KVMs in multi-data center environments** The Management Server was randomly connecting to any of the datacenters if an organization spanned multiple datacenters (for example, dc-1, dc-2). This affected connections to the Cassandra nodes in the local data center for key management and Key Value Map (KVM) operations. |
