    Thanks for the new version; looks like some good stuff.

    I may need to update my IB, which is using the IB interface w/ AmiBroker. What version of IB are you now supporting or have you tested? I’d like to upgrade to the Feb or March version.

    For all of you that get AFL errors with 4.91:
    You have to make sure that your formulas do not use:

    switch, case, break, continue, default

    as variable names. The above words are now reserved AFL keywords
    and must not be used as variable names.

    For more information about these new reserved words please read the Read Me.
