     16Changes in 0.9 Beta:
     17 * Significantly expanded capabilities of [wiki:../wlan_exp experiments framework]
     18  * Added new [wiki:../wlan_exp/examples wlan_exp examples]
     19  * Detailed [wiki:../wlan_exp/log event log] at each node
     20   * Includes every Tx/Rx event in CPU High and CPU Low
     21    * Rx events capture OFDM channel estimates
     22    * Tx Low events capture per-retransmission rate, contention window and backoff values
     23   * Includes association state changes at AP and STA
     24   * Python tools to retrieve log data, parse into numpy structured arrays
     25  * New wlan_exp Python control of:
     26   * Per-node, per-destination locally generated traffic (LTG)
     27   * Tx rate and Tx power per-node, per-destination
     28   * Retrieval / reset of Tx/Rx stats
     29   * Node microsecond timestamp - node timers can be synchronized with broadcast Ethernet packet
     30 * Added duration for LTG schedules; traffic flows can now auto-terminate
     31 * Unified structures for all doubly-linked lists (LTG, scheduler, Tx queue, association table)
     32 * Reserved 16MB of DRAM for user scratch space ({{{DDR3_SCRATCH_SIZE}}} bytes starting at {{{DDR3_SCRATCH_BASEADDR}}})
     33 * Updated to latest hardware support cores (radio_controller, w3_ad_controller)
     34 * MAC/PHY core updates
     35  * Added logic to MAC to capture timestamp of each Tx start
     36  * Added logic to Tx to automatically insert current microsecond timestamp (for beacon frames)
     37  * Added Tx gain param for MPDUO Tx and auto Tx control paths
     38  * Added more pipeline registers to debug outputs in all cores, for easier timing closure
     39 * Added basic floorplanning to UCF in XPS project, for more consistent timing closure
