+===== 3.36.64 (02/09/2018) =====
+  * Added option to prime the fuel rail by running the fuel pump for some amount of time after key on. The option is located on the "ECU Config→Misc" tab. It should default to 0 seconds to simulate stock behavior and you should be able to increase this in half-second steps up to, I think, 30 seconds. When you turn the ignition key on, the pump should run for this many seconds as long as the ignition key is on. If you disrupt this time by turning the ignition key off, the pump should stop immediately and then restart the full prime time again when you next restore the key to the on position.
+===== 3.33.115 (11/27/2016) =====
+  * Added airflow and boost-based fuel cut options. You'll find these in the ECU Config→Fuel tab once you have updated [[http://www.ecmtuning.com/downloads.php|your laptop application]].
+===== 3.28.119 (06/03/2014) =====
+  * Fixed a bug in the ethanol-based interpolation between MinOct and MaxOct tables. Previously, this algorithm was incorrectly using the raw ethanol fuel correction as the interpolation value. This only affects you if you have __**both**__ the "Enable ethanol sensor" __**and**__ the "Interpolate between Min and Max octane based on ethanol content" checkboxes checked.
+===== 3.28.118 (03/25/2014) =====
+  * Fixed a major bug in the previous 1G release (3.28.106) of ECMLink that caused the ECU to reset randomly while logging due to a stack overflow. To fix this issue, we had to make a huge number of changes to the base factory code to free up stack space. This type of change is risky! We've tested extensively, but please be aware of the possibility for more unexpected issues as more people exercise more functionality.
+  * Fixed a relatively minor bug in the 2G that allowed non-zero MAFComp adjustments to randomly creep into SD operation even if you had the "ignore MAFComp while running SD" checkbox checked.
+===== 3.28.106 (03/10/2014) =====
+  * Added support for ethanol adjustment. Use of this function requires that an ethanol sensor be wired to the ECU's MAF input but also requires that you run speed density operation so as to free up the MAF pin. Also added support for interpolating between min and max octane tables based on ethanol content. The application help file has more details.
+  * Added support for a user-editable minimum injector pulsewidth. This value can be used to prevent the ECU from attempting to operate the injector outside of its linear areas of flow. Also added functionality to disable fuel trim lean out when you've already reached the minimum injector pulsewidth. Defining the minimum injector pulsewidth somewhere just below the pulsewidth typically seem at idle on a fully warmed engine seems to help smooth out a number of transitional cases where IPW momentarily dips into non-linear areas of operation as happens sometimes when rolling to a stop with large injectors. If the injectors are large enough, it's even possible to get into a situation where you're operating the injector outside its linear range even at idle! So you may find that you need a minimum IPW so high that your typical idle is at a constant (minimum) pulsewidth.
+  * Made some **significant**  changes to internal code structure. Although this provides no obvious changes to functionality, it does warrant mention simply due to the wide-sweeping impact this change could have on any number of other functions. A lot of testing has been done to ensure that nothing has been broken, but do keep in mind the potential is there for unexpected behavior and/or bugs.
 ===== 3.26.73 (10/09/2013) =====
   * Added hysteresis to low side of coolant temp window on the EGR and FPS output controls.
   * Added check to IdleSw activation of EGR and FPS outputs to ensure that IdleSw is simulated in the RPM/TPS tab before using the IdleSw input for activation.
-  * Fixed bug in cranking fuel cut that required cranking for a period of time without the throttle to the floor first before pressing the throttle down to activate the cut.  Now the check for low throttle angle takes place whether you're cranking or not.  And once flagged good it remains good until the next ECU restart.
+  * Changed cranking fuel cut not to activate the cut unless less than WOT is seen as some point after ECU power-up. This prevents a bad TPS signal from inadvertently triggering cranking fuel cut.
 ===== 3.26.35 (01/03/2013) =====
