Crucial firmware upgrade for SSD

From the email I got today:

"New firmware available for your Crucial® SSD!
Crucial SSDs are designed to support periodic firmware upgrades that provide enhancements to optimize how our drives perform. We're happy to announce that the latest firmware upgrade (040H/04MH) is now available for your Crucial m4, Adrenaline, or mSATA SSD on our SSD support page. This is an optional firmware update, but by upgrading you can benefit from the following improvements:
Faster boot up – we improved the time between when you press the power button on your computer and when the drive is ready to accept commands
Faster TRIM – we improved how our drives clean up files to make them more efficient
Better power management – we improved some power consumption elements so that our drives can draw less power

At Crucial.com, we're proud to deliver first-rate support to our SSD customers and that includes firsthand upgrade news. While you're on Crucial.com downloading the latest firmware, why not see if you can further improve your system's performance with a DRAM upgrade? Our innovative Crucial System Scanner accurately identifies the memory in your system and provides a list of guaranteed-compatible upgrades.

At least its not a bug fix this time. Nice to see they are continually improving the product to keep it competitive.
