+Changes in 1.0 Beta:
+
+'''PHY/MAC Hardware Changes:'''
+ * Updated w3_clock_controller to [browser:/PlatformSupport/CustomPeripherals/pcores/w3_clock_controller_axi_v3_01_b version 3.01.b]
+ * Increased maximum number of backoff slots to 65k (was 2047 in previous releases)
+ * Reduced the size of the Tx and Rx packet buffers. There are now 8 4KB Tx buffers and 8 4KB Rx buffers (previously 16 each). The reference code only uses 3 Tx buffers and 2 simultaneous Rx buffers; extra buffer space is available for custom applications.
+ * Cleaned Tx and Rx PHY init scripts. Updated Tx init script simplifies creation of new waveform files for Rx simulation.
+ * Added new waveform files for simulating the Rx PHY (in [browser:/ReferenceDesigns/w3_802.11/sysgen/wlan_phy_rx_pmd/rx_sigs /wlan_phy_rx_pmd/rx_sigs]). Each waveform represents a valid 802.11 frame with various packet contents and modulation/coding rates.
+
+'''MAC Software Changes:'''
+ * Reworked handshake between CPU High and Low for new transmissions, removing the {{{IPC_MBOX_TX_MPDU_ACCEPT}}} message. See the [wiki:../PacketFlow Packet Flow] page for details.
+ * Fixed race condition in creation of LTG scheduled events ([changeset:3980 rev 3980])
+ * Updated wlan_mac_low.c to explicitly write the MAC core's auto-inserted timestamp value to the Tx pkt buffer after transmitting a beacon, so the packet payload in the log matches the transmitted payload ([changeset:3981 rev 3981])
+ * Updated contract for {{{queue_checkout_list()}}} to return number of successfully checked-out queue entries ([changeset:3968 rev 3968])
+ * Updated definition of "length" across the codebase to ensure any length which includes the MAC header (typically 24 bytes) also includes the FCS (4 bytes), consistent with the standard's definition
+ * Added utility functions to stop and restore the en/disable state of the interrupt controller and updated application and framework code to use new functions throughout. Application code can pause interrupts as needed, restoring the previous state when finished:
+{{{
+interrupt_state_t prev_interrupt_state; 
+prev_interrupt_state = wlan_mac_high_interrupt_stop();
+
+//Do Non-Interrupt Safe Stuff Here
+
+wlan_mac_high_interrupt_restore_state(prev_interrupt_state);

-= 802.11 Reference Design: Changelog =
+'''wlan_exp Framework Changes:'''
+ * Extensive documentation of Python classes and methods. wlan_exp docs now available at [//docs/mango-wlan-exp warpproject.org/docs/mango-wlan-exp] and in the {{{/python/docs}}} directory of the reference design .zip archive
+ * Fixed retrieval of Tx/Rx stats from IBSS node for unknown partner node; a valid stats struct is now returned with all zero values
+ * Updated example scripts to better handle unexpected log contents
