    17 If you already have a 0.11 version of Trac installed via `easy_install`, it might be easiest to also use `easy_install` to upgrade your Trac installation:
    18

    20 # easy_install --upgrade Trac==0.12

    7575=== 6. Steps specific to a given Trac version  ===
     76
     77==== Upgrading from Trac 0.12 to Trac 1.0 ==== #to1.0
     78
     79===== Python 2.4 no longer supported =====
     80The minimum supported version of python is now 2.5
     81
     82===== Subversion components not enabled by default for new installations
     83The Trac components for Subversion support are no longer enabled by default. To enable the svn support, you need to make sure the `tracopt.versioncontrol.svn` components are enabled, for example by setting the following in the TracIni:
     84{{{
     85[components]
     86tracopt.versioncontrol.svn.* = enabled
     87}}}
     88The upgrade procedure should take care of this and change the TracIni appropriately, unless you already had the svn components explicitly disabled.
     89
     90
     91===== Attachments migrated to new location
     92Another step in the automatic upgrade will change the way the attachments are stored. If you're a bit paranoid, you might want to take a backup of the `attachments` directory before upgrading (but if you are, you already did a full copy of the environment, no?). In case the `attachments` directory contains some files which are //not// attachments, the last step of the migration to the new layout will fail: the deletion of the now unused `attachments` directory can't be done if there are still files and folders in it. You may ignore this error, but better go have a look to these files, move them elsewhere and remove the `attachments` directory manually to cleanup the environment. The attachments themselves are now all located in your environment below the `files/attachments` directory.
     93
     94===== Behavior of `[ticket] default_owner` changed
     95Prior 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.

    … …  
    92114===== Resynchronize the Trac Environment Against the Source Code Repository =====
    93115
    94 Each [TracEnvironment Trac environment] must be resynchronized against the source code repository in order to avoid errors such as "[http://trac.edgewall.org/ticket/6120 No changeset ??? in the repository]" while browsing the source through the Trac interface:

    103125While you can keep the same synchronization as in 0.11 adding the post-commit hook as outlined in TracRepositoryAdmin#Synchronization and TracRepositoryAdmin#ExplicitSync will allow more efficient synchronization and is more or less required for multiple repositories.
    104126
    105 Note that if you were using the `trac-post-commit-hook`, ''you're strongly advised to upgrade it'' to the new hook documented in the above references, as the old hook will not work with anything else than the default repository and even for this case, it won't trigger the appropriate notifications.
