Bertrand Delacretaz commented on SLING-7844:
--------------------------------------------
Earlier, Jason said:
{quote}There is a configuration option in place right now, so if there is a
need to change the default, it's a simple change
{quote}
So I think changing the default value of that configuration to "legacy mode"
should fulfill our backward compatibility requirements? And maybe log an INFO
message if that legacy mode is active, and document it at
[https://sling.apache.org/documentation/bundles/rendering-content-default-get-servlets.html]
to give new users a good chance of finding that setting?
IIUC that configuration is the DefaultGetServlet's "ecmaSupport" parameter, if
that's correct I think a better label would be "Legacy ECMA date format" and
description "Enable legacy Sling ECMA format for dates" to make things clearer.
