Inset in 2.79b: How to stick with the last used value?

In Blender 2.78c, when I used the Inset tool for the first time on a project, it would come with the default value, for example Depth: 0. Then I could edit the value on the operator or via F6 key to Depth: 0.2. After that, I could go about my business, adding more primitives, editing nodes, and so on. So, when I used the Inset tool again in the same work session, the Depth value was saved and I didn’t need to insert a Depth of 0.2 again. Now, in Blender 2.79b, the values always return to their defaults every time I use the Inset tool (not knowing if it is limited to this tool).

My question is: Is there a way to make the last used value “stick” to the tool as they used to in version 2.78c?
