This repository contains the code for "Old SES": the one whose default export is a single object named SES, which has a property named SES.makeSESRootRealm(). This code was used to make all NPM releases of the SES package up through the '0.6.x' series.
Modern SES development is now happening in the SES-shim repository. This "New SES" has a named export named lockdown(), which introduces the Compartment constructor (and the harden function) into the global environment. That code is used to make NPM releases of SES starting with the '0.7.x' series.
The old SES code was used to populate the packages/ses/ directory in the New SES reposotiry.
Developers who need to make more releases in the '0.6.x' series should use the 0.6-stable branch of this repository. The trunk is left empty to avoid confusion.
