+== Other Modifications made to the 1.0 API
+
+=== Modified Interfaces
+
+==== `IWikiChangeListener`            ^[source:trunk/trac/wiki/api.py@13198:53#L32 (1.1.3)] [source:branches/1.0-stable/trac/wiki/api.py@11490#L33 (1.0)]^ #IWikiChangeListener
+
+Wiki page version comments can now be edited, so `wiki_page_comment_modified(page, old_comment)` has been added to allow plugins to be notified of this.
+
+==== `IPreferencePanelProvider`            ^[source:trunk/trac/prefs/api.py@13510:23#L17 (1.1.3)] [source:branches/1.0-stable/trac/prefs/api.py@11490#L17 (1.0)]^ #IPreferencePanelProvider
+
+[wiki:TracDev/PluginDevelopment/ExtensionPoints/trac.prefs.api.IPreferencePanelProvider IPreferencePanelProvider] implementations can now provide child panels that appear as sections appended to other panels ([wiki:TracDev/Proposals/AdvancedNotification#Modularpreferencepages proposal]). This allows plugins to extend existing preference panels.
+
+=== New Interfaces
+
+==== `trac.notification.api.INotificationDistributor` ^[source:trunk/trac/notification/api.py@13454#L29 (1.1.3)]^ #INotificationDistributor
+
+A new [wiki:TracDev/PluginDevelopment/ExtensionPoints/trac.notification.api.INotificationDistributor INotificationDistributor] interface was added ([wiki:TracDev/Proposals/AdvancedNotification#ExtensionAPIformaildistribution proposal]). It allows plugins to distribute notifications on different channels (e.g. over XMPP).
+
+==== `trac.notification.api.INotificationFormatter` ^[source:trunk/trac/notification/api.py@13454#L46 (1.1.3)]^ #INotificationFormatter
+
+A new [wiki:TracDev/PluginDevelopment/ExtensionPoints/trac.notification.api.INotificationFormatter INotificationFormatter] interface was added ([wiki:TracDev/Proposals/AdvancedNotification#ExtensionAPIformaildistribution proposal]). It allows plugins to format notifications (e.g. to HTML).
+
+==== `trac.notification.api.INotificationSubscriber` ^[source:trunk/trac/notification/api.py@13469#L70 (1.1.3)]^ #INotificationSubscriber
+
+A new [wiki:TracDev/PluginDevelopment/ExtensionPoints/trac.notification.api.INotificationSubscriber INotificationSubscriber] interface was added ([wiki:TracDev/Proposals/AdvancedNotification#ExtensionAPIforsubscriptions proposal]). It allows plugins to provide more subscription preferences (e.g. to send or suppress notifications under special conditions).
+
+==== `trac.notification.api.IEmailAddressResolver` ^[source:trunk/trac/notification/api.py@13454#L67 (1.1.3)]^ #IEmailAddressResolver
+
+A new [wiki:TracDev/PluginDevelopment/ExtensionPoints/trac.notification.api.IEmailAddressResolver IEmailAddressResolver] interface was added ([wiki:TracDev/Proposals/AdvancedNotification#ExtensionAPIformaildistribution proposal]). It allows plugins to retrieve email addresses from users (e.g. from LDAP).
+
+==== `trac.notification.api.IEmailDecorator` ^[source:trunk/trac/notification/api.py@13454#L79 (1.1.3)]^ #IEmailDecorator
+
+A new [wiki:TracDev/PluginDevelopment/ExtensionPoints/trac.notification.api.IEmailDecorator IEmailDecorator] interface was added ([wiki:TracDev/Proposals/AdvancedNotification#ExtensionAPIformaildistribution proposal]). It allows plugins to add or tweak email headers.
+
+=== Notification API Changes
+
+To take advantage of the new notification related interfaces, code that sends notifications must use the new [wiki:TracDev/NotificationApi Notification API] instead of the `NotifyEmail` class hierarchy since  Trac 1.1.3. (See [wiki:TracDev/Proposals/AdvancedNotification#ExtensionAPIformaildistribution proposal])
+
+=== Database API Changes
+
+In Trac 1.1.3 methods have been added to the `DatabaseManager` class for settings and retrieving the database version for Trac and plugins: `set_database_version` and `get_database_version` (#11859).
+
+In Trac 1.1.5 methods have been added to the `DatabaseManager`class for upgrading the database: `needs_upgrade` and `upgrade`.
+
+==== `Environment.get_db_cnx` has been removed in Trac 1.1.2 #get_db_cnx
+
+Following the [../0.12#get_db_cnx deprecation] made in 0.12, the method `Environment.get_db_cnx` has been removed (#11605).
+
+One should now only use the //context managers// for retrieving a database Connection in read or write mode.
+ - a **read-only** Connection can be used to form queries:
+   {{{#!python
+   with env.db_query as db:
+       ...
+   }}}
+   a `db` instance obtained the above way should only be used for executing //SELECT//
+   queries 
+ - a **writable** Connection can be used to modify the database content in a transaction:
+   {{{#!python
+   with env.db_transaction as db:
+       ...
+   }}}
+   a `db` instance obtained the above way can be used to execute //INSERT/UPDATE/DELETE//
+   queries; they will be committed when the last such automatic transaction 
+   in the control flow completes successfully. See DatabaseApi for the full details.
+
+`Environment.get_read_db` and the decorators `@with_transaction(env)` and `env.with_transaction()` have been [../1.0#with_transaction deprecated] since Trac 1.0 and will be removed in Trac 1.3.1.
+
+
+==== `db` parameters removed from function and method signatures in Trac 1.1.2
+
+With the introduction of `@with_transaction(env)` decorators in 0.12 and continuing with the introduction of the database connection context managers in 1.0, the `db` parameters passed as function and method arguments became [../0.12#Othernews deprecated].
+
+The `db` parameters have been removed from nearly all function and method signatures. The `db` arguments are still present on methods of `IEnvironmentParticipant` implementations, but are deprecated and should no longer be used. They will be removed in 1.3.1.
+
+
+==== `ConnectionBase` class in Trac 1.1.2
+
+The `ConnectionBase` class defines an abstract interface that database backends must adhere to when implementing a `Connection` class.
+
+
+=== Template and CSS changes in Trac 1.1.2
+
+`tt` tags are not supported in HTML5 and have been replaced with `code` tags in Trac (#11094). The styling of `tt` and `code` tags is the same in Trac, but `code` tags should be used, since the styling for `tt` tags will be removed in a future version of Trac.
+
+The `about.css` stylesheet has been removed and the rules contained in that stylesheet have been moved to `trac.css`. The table of environment information on the //Error// and //About// pages have been extracted to a new template `environment_info.html` and the markup and associated rules in the stylesheet have been significantly changed.
+
+=== Uncategorized Changes
+
+Removed deprecated compatibility code for InterTrac links in Trac 1.1.4: [browser:/trunk/trac/wiki/formatter.py@13050:703-712#L696], and remove documentation:
+* InterWiki page
+* [browser:/trunk/trac/wiki/intertrac.py@13050:50-60#L30]
+
+Removed the deprecated `authname` parameter from `Environment.get_repository()` in Trac 1.1.3.
+
+Removed //Since// info from docstrings for Trac < 0.12.
+
