+Routes containing :any
+======================
+
+Historically, CodeIgniter has always provided the **:any** wildcard in
+routing, with the intention of providing a way to match any character
+**within** an URI segment.
+
+However, the **:any** wildcard is actually just an alias for a regular
+expression and used to be executed in that manner as **.+**. This is
+considered a bug, as it also matches the / (forward slash) character, which
+is the URI segment delimiter and that was never the intention.
 
-However, the **:any** wildcard is actually just an alias for a regular expression
-and used to be executed in that manner as **.+**. This is considered a bug, as it

+There are certainly many developers that have utilized this bug as an actual
+feature. If you're one of them and want to match a forward slash, please use
+the **.+** regular expression::
 
 	(.+)	// matches ANYTHING
 	(:any)	// matches any character, except for '/'
 
+Directories and 'default_controller', '404_override'
+====================================================
+
+As you should know, the ``$route['default_controller']`` and
+``$route['404_override']`` settings accept not only a controller name, but
+also *controller/method* pairs. However, a bug in the routing logic has
+made it possible for some users to use that as *directory/controller*
+instead.
+
+As already said, this behavior was incidental and was never intended, nor
+documented. If you've relied on it, your application will break with
+CodeIgniter 3.0.
+
+Another notable change in version 3 is that 'default_controller' and
+'404_override' are now applied *per directory*. To explain what this means,
+let's take the following example::
+
+	$route['default_controller'] = 'main';
+
+Now, assuming that your website is located at *example.com*, you already
+know that if a user visits ``http://example.com/``, the above setting will
+cause your 'Main' controller to be loaded.
+
+However, what happens if you have an *application/controllers/admin/*
+directory and the user visits ``http://example.com/admin/``?
+In CodeIgniter 3, the router will look for a 'Main' controller under the
+admin/ directory as well. If not found, it will fallback to the parent
+(*application/controllers/*) directory, like in version 2.x.
+
+The same rule applies to the '404_override' setting.
+

From 6c7c8917d853bcd4acdce930b9afa537b2fb8b95 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@devilix.net>

Subject: Remove 'autoinit' DB setting

It doesn't make sense to do a load->database() call
but not connect to the database. IIRC there was more
stuff in CI_DB_driver::initialize() at some point,
so that was probably the reason why the setting
existed in the first place. However, now it only
results in users making invalid bug reports because
they don't understand the feature ...

Examples during just the past 2 weeks: #3571 #3601 #3607

+The $config['global_xss_filtering'] setting
+===========================================
+
+As already explained above, XSS filtering should not be done on input data,
+but on output instead. Therefore, the ``$config['global_xss_filtering']``,
+which automatically filters *input* data, is considered a bad practice and
+is now deprecated.

+Instead, you should manually escape any user-provided data via the

Subject: Fix #3627: Keep timed locks for more than 5 seconds

Emulated locks for Redis and Memcached now have a TTL
of 300 seconds (the default HTTP request timeout value
on many environments) and 30 attemps, each separated by
sleep(1), are made by the blocked request to try and
obtain a lock if it has been freed.

Additionaly, the blocking time for MySQL's locks,
which are also timed, is also set to 300 seconds.

 Encryption Library
 ##################
 
+.. important:: DO NOT use this or any other *encryption* library for
+	user password storage! Passwords must be *hashed* instead, and you
+	should do that via PHP's own `Password Hashing extension
+	<http://php.net/password>`_.

 The Encryption Library provides two-way data encryption. To do so in
 a cryptographically secure way, it utilizes PHP extensions that are
 unfortunately not always available on all systems.

Subject: Fixed bugs in form_validation for methods matches, differs, and
 valid_base64. Implemented tests for valid and invalid inputs for all basic
 rules available for form_validation. The invalid input data currently doesn't
 pass all tests.

 For example, when a call is made to:
 
-	http&#58;//example.com/news/latest/10
+	http://example.com/news/latest/10
 
 We might imagine that there is a controller named "news". The method
 being called on news would be "latest". The news method's job could be to
 grab 10 news items, and render them on the page. Very often in MVC,
 you'll see URL patterns that match:
 
-	http&#58;//example.com/[controller-class]/[controller-method]/[arguments]
+	http://example.com/[controller-class]/[controller-method]/[arguments]
 
 As URL schemes become more complex, this may change. But for now, this
 is all we will need to know.

Subject: Edit dbforge drop_table line 230

At current the documentation does not distinguish between DROP TABLE IF EXISTS table_name and DROP TABLE table_name. As seen by the DB_forge.php class in system/database; the function accepts a Boolean as the second parameter as to whether or not to apply the IF EXISTS mysql condition.
