+'''Changes in v1.7.5:'''
+
+This release includes updated [wiki:../Benchmarks/Rx_Char Rx sensitivity] characterization results for the OFDM and DSSS receivers. All PHY modes exceed the sensitivity requirements of the 802.11 spec.
+
+'''PHY and MAC Hardware Changes:'''[[BR]]
+ * Added support for OFDM and DSSS receptions without packet detection. At low SNR the receivers don't require AGC, so there's no need for packet detection before the PHY reception. The OFDM Rx starts on an LTF correlation event; the DSSS Rx starts on a SYNC field detection. If packet detection fires the AGC will be triggered, but this is no longer required before a PHY Rx event.
+
+''Python changes:'''[[BR]]
+ * Added {{{require_pkt_det }}} arguments to {{{n.configure_ofdm_pkt_det()}}} and {{{n.configure_dsss_pkt_det()}}} methods to configure whether the Rx PHYs attempt receptions without explicit packet detection.
