v4.2172 (01 Feb 2011)

Features:

• Improved SD card interoperability with Pentax K series cameras
• Improved stand-by power consumption in Eye-Fi connected cameras
• Better post-format and power-on SD reset behavior in some cameras to improve interoperability
• Increased the number of uploaded files that can be removed via endless memory processing for each sequence of four power-cycles
• Improved prioritization of pending upload work over endless memory processing
• Increased number of retries during 802.11 association failures when adding a new network profile
• Control WPA supplication parameters directly instead of relying on the Marvell driver to improve 802.11 interoperability in WPA/WPA2 modes
• Incorporated new firmware from Marvell
• Reduced maximum 802.11 power selected while operating in card readers to improve operation with marginal USB power supplies
• Changed expired breadcrumb clean-up processing to a random probabilistic scheme for better stand-by power

Fixes:

• Fixed NULL pointer bug in expiring old wireless scan results while they were being used actively
• Dynamic calibration for mutual component tolerance sensitivity with some Apple Airport (and a few other) access points

NOTE: For customers with Eye-Fi X2 Cards running firmware version 4.1017 or earlier, the firmware update may result in a failure message after the 30-second countdown. If this occurs, please do not be alarmed and follow the instructions to remove your Eye-Fi Card and reinsert it. If you do not get prompted for a firmware update again after reinserting card, the firmware update was completed successfully despite the erroneous message.
