Change log for 4.5.6

[UKMIITB]

It looks like new version has been published for this. Can you add in release & share the change log for this

Also the documentation recommends using sqlite 2.2.0, but 2.4.0 is available now. Any chance of testing this with latest version & officially updating the documentation

Hello @UKMIITB,

Thank you for your interest in SQLCipher for Android. The changes included within the 4.5.6 of SQLCipher for Android can be found here. SQLCipher core, which is included within SQLCipher for Android includes a changelog here. The main adjustments with the Android library in this release are:

• Fix to close non-primary connections from the pool when changing the password
• Adding ProGuard support
• Include a license file
• Update README documentation

We will consider documentation communication for a future release, along with the update to the sqlite reference.
