Caja version used with Google Apps Script

Question

Does Google Apps Script use the latest release of Caja for HtmlService or does it lag behind somewhat?

Answer 1

There is difference between latest Caja version and the Caja version of GAS.

• Caja version in the Caja Playground is 5065
• GAS Caja version is 4969m

The version information is stored in the cajolerVersion "variable" of HTML code produced by Caja.

Answer 2

There is no way to access the version inside Apps Script although that's an interesting feature request. As a general rule, Apps Script lags Caja by about 2 weeks, give or take.
