Alternate downloads for MacOS: Since MacOS Mojave (10.14), application access to the user's Desktop, Documents, and Downloads folders must be explicitly granted by the user. When the application first accesses such a folder, MacOS raises a dialog to request access. If the user grants access, then the application can read/write folders and files under that folder hierarchy until the user revokes the privilege. However, this mechanism only works for application binaries, not a script-launched application. For this reason, we now offer 3 versions of the FC application bundle for MacOS. For more details, see the Downloads page.
Minor bug fix: In release 5.2.1, we made some changes to the tick mark label generation algorithm to support scientific notation. However, this led to an issue where a tick mark essentially at "0" would be expressed in scientific notation because it wasn't exactly zero (due to the floating-point math used to compute the tick values). This release adjusted the algorithm to treat values very close to 0 (relative to the tick interval size) on a linear axis as exactly 0.
