During the process of adding support for double precision numbers from single precision floating-point numbers, there was an inadvertent change to the sierraChart.h header file in version 2917 that should not have been made. This will have caused compatibility issues with custom studies compiled with versions 2916 and earlier. This type of compatibility issue would would result in instability when using those studies and complete failure in many cases. The usual response to this type problem is that users will just recompile their studies when using versions 2917 and higher. However, we have now corrected the problem in 2921. Therefore, when updating to version 2921 or higher, and you have recompiled your custom studies using version 2917 through 2920 you need to recompile again. We apologize for this issue. Version 2921 at this time is a pre-release. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
