+Quisk Version 4.2.34  May 2024
+==============================
+For the Hermes-Lite2 the inhibit Tx function (CN8) now releases the Spot button.
+
+Quisk displays the band plan below the X-axis as colored bars, and there are eighteen possible colors.
+If you hover the mouse over a bar, Quisk now displays the name of the mode. Recall that there is a dialog
+box so you can set the band plan to what you want.
+ 
+Quisk Version 4.2.33  May 2024
+==============================
+Added the get_level Hamlib command "l STRENGTH". It returns the S-meter reading. I finally found some Hamlib
+documentation, often not an easy task.  The return value of STRENGTH is in dB with zero dB equal to S9.
+There are 6 dB per S-unit. So a STRENGTH of 4 is 4dB over S9, and -6, -12, -18 is S8, S7, S6. I also added
+the corresponding FlexRadio command ZZSM.
+
+Quisk Version 4.2.32  April 2024
+================================
+I found and fixed a bug in the microphone filters that can result in a buffer overrun. You should update Quisk.
+
+Some Linux digital programs can not use the usual Quisk Pulse loopback device and must use an
+Alsa loopback. I added more documentation for Alsa loopbacks, added more information on the Sound
+screen and I changed the default Alsa sample size to 16 bit.
+
+Quisk now responds to the Hermes Lite2 Tx inhibit input by displaying a message and extinguishing the "Tx" light.
+There is a new item "Hermes Lite2 protocol" on the Hardware screen to control this behavior.
+
+Quisk Version 4.2.31  March 2024
+================================
+The "Tune" item was missing from the Midi menus. I fixed it but I didn't test it because I did
+not borrow Ben's Midi controller. Please test it yourself and let me know if it works. The Midi
+speed can be set from the menu too.
+
+Quisk Version 4.2.30  March 2024
+================================
+A new option "Tx-Rx silence msec" on the Timing configuration screen controls how long
+to suppress Rx audio when switching from Tx to Rx. The previous fixed time was 50 msec.
+
+The SSB squelch control now works on CW too. Please test.
+
 Quisk Version 4.2.29  January 2024
 ==================================
 This version updates the FreeDV library files and program logic. I added a "Monitor"
