 Check whether your plugins are compatible with the version of Trac that you are upgrading to. Obsolete plugins listed in the [#VersionSpecificSteps version specific steps] below should be uninstalled or disabled.
 
-If you are upgrading to a minor release, plugin compatibility is usually not a concern because the Trac API rarely changes, and major features are usually not introduced, for minor releases.
-
-If your plugins are installed from [https://trac-hacks.org trac-hacks.org] you can check compatibility by looking for a tag on the project page corresponding to a major release (e.g. `1.2`). If you are unsure, you'll want to contact the plugin author or ask on the [trac:MailingList MailingList].

 If you are running several Trac plugins it is good to test the upgrade and plugin functionality in a staging instance of your site before upgrading your production instance. Remember, plugin authors are responsible for Trac version compatibility and plugins can interact in unexpected ways. Your Trac instance may have a unique combination of plugins and therefore it's advised that you do some verification testing when making any changes to your site.

If it was installed through a Windows installer, uninstall the old Trac package before installing new Trac package.
 
 If you are managing your Trac installation using command line tools, `pip` is the preferred tool to upgrade a Trac instance because it will uninstall the old version. The following command will upgrade your Trac installation using the package published to [https://pypi.python.org/pypi/Trac PyPI].

 ===== New permission policies for Wiki and Ticket realms
 
-Since 1.3.2 there are new permission policies for the ticket and wiki systems. `DefaultTicketPolicy` allows an authenticated users with `TICKET_APPEND` or `TICKET_CHPROP` to modify the description of a ticket they reported. It also implements the pre-1.3.2 behavior of allowing users to edit their own ticket comments. [#Newpermissionspolicyforread-onlywikipages ReadonlyWikiPolicy], added in 1.1.2, is renamed to `DefaultWikiPolicy`. The new permission policies can be easily replaced with alternate implementations if the default behavior is not desired.

 Reports that display the error need to be modified to prefix the `description` column with the appropriate table name or alias. For example, if the `ticket` table is aliased as `t` (`ticket t` or `ticket AS t`), replace `description` with `t.description` if the report should use the ticket's `description` column.

 If other permission policies are enabled, `trac.ini` will need to have `ReadonlyWikiPolicy` appended to the list of active `permission_policies`. See TracFineGrainedPermissions#ReadonlyWikiPolicy for additional details on the proper ordering.
 
+===== Navigation Ordering Moved
+
+The mainnav and metanav configuration ordering have
+been moved from `[trac]` `mainnav` and `[trac]` `metanav` to the `[mainnav]` and `[metanav]` sections. The ordering is now specified using the `order` attribute as described in [TracNavigation#nav-order TracNavigation].
+
+The new configuration values will be written to trac.ini on upgrade, preserving the navigation order for the environment. You may need to edit trac.ini
+if you use a shared [TracIni#GlobalConfiguration global configuration].
+For example, if you wish to specify the navigation ordering for several environments in `global.ini`, you'll
+need to add the `[mainnav]` and `[metanav]` sections
+in that file and delete those sections from each
+environment's trac.ini.

 Prior to 1.0, the owner field of new tickets always defaulted to `[ticket] default_owner` when the value was not empty. If the value was empty, the owner field defaulted to to the Component's owner. In 1.0 and later, the `default_owner` must be set to `< default >` to make new tickets default to the Component's owner. This change allows the `default_owner` to be set to an empty value if no default owner is desired.
 
+===== Behavior of `* -> *` workflow transition
+
+The workflow transition `* -> *` must have the operation
+`leave_status`. Due to a defect in Trac < 1.0.18
+`leave_status` was not required, so it may be necessary
+to add the operation when upgrading. The action will not
+display for a `* -> *` transition if the action does
+not have the `leave_status` operation.
