Re: [Quantlib-users] QuantLib 1.29 released

[Luigi B. <lui...@gm...>]

Hello Roberto,
    no, it's still a bad idea to share objects between threads.  Like in
previous releases, the Settings class and other singletons can be
per-thread instead of globals depending on a configuration switch, but the
code in itself is not multi-threaded.  What changed is only that, in order
to enable per-thread singletons, you no longer need to explicitly define
the sessionId function.  It's a convenience.

Hope this helps,
    Luigi
