For those that are interested,

I was doing some digging and found the release schedule for chrome and firefox.  Chrome version 44 comes out May 15th, with version 45 following on June 26th. Firefox ESR version 38 will be released on May 19th, support for version 31 will end on August 11th.

If you would like to reference this information and look at more future date information.
