    18 If you do a manual (not operating system-specific) upgrade, you should also stop any running Trac servers before the installation. Doing "hot" upgrades is not advised, especially on Windows ([trac:#7265]).

    20 You may also want to remove the pre-existing Trac code by deleting the `trac` directory from the Python `lib/site-packages` directory, or remove Trac `.egg` files from former versions. 
    21 The location of the site-packages directory depends on the operating system and the location in which Python was installed. However, the following locations are typical:

     22The location of the site-packages directory depends on the operating system, and the location in which Python was installed. However, the following locations are common:

    2324 * on Windows: `C:\Python2.X\lib\site-packages` 
    2425 * on MacOSX: `/Library/Python/2.X/site-packages` 
    2526 
    26 You may also want to remove the Trac `cgi-bin`, `htdocs`, `templates` and `wiki-default` directories that are commonly found in a directory called `share/trac`. (The exact location depends on your platform.)

    28 This cleanup is not mandatory, but makes it easier to troubleshoot issues later on, as you won't waste your time looking at code or templates from a previous release that are not being used anymore... As usual, make a backup before actually deleting things.

     73Some web browsers cache the CSS and Javascript file in a strong way, so you'll perhaps need to refresh the cache of the browsers by a force reload (and tell your users to do so!).

    7475=== 6. Steps specific to a given Trac version  === 
    … …  
    7879 
    7980===== SQLite v3.x required ===== 
    80 SQLite v2.x is no longer supported. If you still use a Trac database of this format, you'll need to convert it to SQLite v3.x first. See [trac:PySqlite#UpgradingSQLitefrom2.xto3.x] for details. 
    81  
    82 ===== PySqlite 2 required ===== 
    83 PySqlite 1.1.x is no longer supported. Please install 2.5.5 or later if possible (see [#Tracdatabaseupgrade Trac database upgrade] below). 
     81SQLite v2.x is no longer supported, if you happen to still use a Trac database using this format, you'll need to convert it to SQLite v3.x first. See [trac:PySqlite#UpgradingSQLitefrom2.xto3.x] for details. 
    8482 
    8583===== Multiple Repository Support ===== 
    86 The latest version includes support for multiple repositories. If you plan to add more repositories to your Trac instance, please refer to TracRepositoryAdmin#Migration. 
     84If you plan to add more repositories to your Trac instance, as this is now possible with the newly introduced multiple repository support, please refer to TracRepositoryAdmin#Migration. 
    8785 
    88 This may be of interest to users with only one repository, since there's now a way to avoid the potentially costly resync check at every request. 
     86This can be of interest even if you only have one repository, as there's now a way to avoid the potentially costly resync check at every request. 
    8987 
    9088===== Improved repository synchronization ===== 
    91 In addition to supporting multiple repositories, there is now a more efficient method for synchronizing Trac and your repositories. 
     89In addition to supporting multiple repositories, a new more efficient method for synchronizing Trac and your repositories was implemented. 
    9290 
    9391While 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. 
    9492 
    9593Note 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. 
    96  
    97 ===== Authz permission checking ===== 
    98 The authz permission checking has been migrated to a fine-grained permission policy. If you use authz permissions (aka `[trac] authz_file` and `authz_module_name`), you must add `AuthzSourcePolicy` in front of your permission policies in `[trac] permission_policies`. You must also remove `BROWSER_VIEW`, `CHANGESET_VIEW`, `FILE_VIEW` and `LOG_VIEW` from your global permissions (with `trac-admin $ENV permission remove` or the "Permissions" admin panel).

    10095==== Upgrading from Trac 0.10 to Trac 0.11 ==== 
    … …  
    105100 
    106101===== Trac Macros, Plugins ===== 
    107 The Trac macros will need to be adapted, as the old-style wiki-macros are not supported anymore (due to the drop of [trac:ClearSilver] and the HDF); they need to be converted to the new-style macros, see WikiMacros. When they are converted to the new style, they need to be placed into the plugins directory instead and not wiki-macros, which is no longer scanned for macros or plugins.

When they are converted to the new style, they need to be placed into the plugins directory instead and not wiki-macros, which is no longer scanned for macros or plugins.

    109104===== For FCGI/WSGI/CGI users ===== 
    … …  
    130125`trac-admin` will not delete or remove default wiki pages that were present in a previous version but are no longer in the new version. 
    131126 
    132 === Trac database upgrade === 
    133  
    134 A known issue in some versions of PySqlite (2.5.2-2.5.4) prevents the trac-admin upgrade script from successfully upgrading the database format. It is advised to use either a newer or older version of the sqlite python bindings to avoid this error. For more details see ticket [trac:#9434]. 
    135  
    136 == Upgrading Python == 
    137  
    138 Upgrading Python to a newer version will require reinstallation of Python packages: Trac of course; also [http://pypi.python.org/pypi/setuptools easy_install], if you've been using that.  Assuming you're using Subversion, you'll also need to upgrade the Python bindings for svn. 
    139  
    140 === Windows and Python 2.6 === 
    141  
    142 If you've been using !CollabNet's Subversion package, you may need to uninstall that in favor of [http://alagazam.net/ Algazam], which has the Python bindings readily available (see TracSubversion).  The good news is, that works with no tweaking.
