[chaley]

CC prerelease 3.2.5a has been published and will available soon to people who are members of the CC prerelease program.

This prerelease contains minor changes. As before, it is likely to be what is released to the general public in approximately a week, once we have had some testing time with it running with the next calibre release (1.6).

Prerelease 3.2.5a has the following changes:

• Repaint the main window after returning from preferences so that cover size changes take effect immediately.
• Improve performance of metadata updating while connected by eliminating an unneeded database operation.
• Remove the code that was causing "security exceptions" in kitkat
• Include a newer version of Google's support library in hopes that it has improved.
• [BUG FIX] Prevent crash when sending email from CC and the device has no email client.
• [BUG FIX] Reset the grouping drawer after a search so that the book counts are correct.
