 Environment upgrades are not necessary for minor version releases unless otherwise noted. 
 
 After restarting, Trac should show the instances which need a manual upgrade via the automated upgrade scripts to ease the pain. These scripts are run via [TracAdmin trac-admin]:
-{{{#!sh
+```
 trac-admin /path/to/projenv upgrade
-}}}
+```
 
 This command will not have any effect if the environment is already up-to-date.
 
 Note that a backup of your database will be performed automatically prior to the upgrade. 
 This feature is relatively new for PostgreSQL or MySQL databases, so if it fails, you will have to backup the database manually. Then, to perform the actual upgrade:
-{{{#!sh
+```
 trac-admin /path/to/projenv upgrade --no-backup

 === 4. Update the Trac Documentation === #UpdatetheTracDocumentation
 
 By default, every [TracEnvironment Trac environment] includes a copy of the Trac documentation for the installed version. However, to keep the included documentation in sync with the installed version of Trac, use the following [TracAdmin trac-admin] command to upgrade the documentation:
-{{{#!sh
+```
 trac-admin /path/to/projenv wiki upgrade

+```
 
 Note that this procedure will leave your `WikiStart` page intact.
 
 === 5. Refresh static resources
 
 If you have set up a web server to give out static resources directly (accessed using the `/chrome/` URL) then you will need to refresh them using the same command:
-{{{#!sh
+```
 trac-admin /path/to/env deploy /deploy/path
-}}}
+```
 
 This will extract static resources and CGI scripts (`trac.wsgi`, etc) from new Trac version and its plugins into `/deploy/path`.
 
 Some web browsers (IE, Opera) cache CSS and Javascript files aggressively, so you may need to instruct your users to manually erase the contents of their browser's cache, a forced refreshed (`<F5>`) should be enough.

 Since 1.1.2 the read-only attribute of wiki pages is enabled and enforced only when `ReadonlyWikiPolicy` is in the list of active permission policies. If `[trac] permission_policy` has the default value `DefaultPermissionPolicy, LegacyAttachmentPolicy`, then `ReadonlyWikiPolicy` should be automatically appended to the list when upgrading the environment:
