[1.1.0-rc1] - 2025-09-19

Minor feature release with bug fixes.

Fixed

• #15: xPrintFloat() printed an extra digit, which would appear as a ‘rounding error’ in decimal representations.

• Width detection of platform-specific built-in integer types (i.e., short, int, long, and long long). The previous implementation included stdint.h with __STDC_LIMIT_MACROS defined. However, if the application source, then included stdint.h before xchange.h, then the fixed-width integer limits were left undefined. As a result, we no longer rely on stdint.h providing these limits.

Added

• xParseFloat() to parse floats without rounding errors that might result if parsing as double and then casting as float.

[1.0.1] - 2025-07-01

Bug fix release.

Fixed

• Handling of serialized strings in xClearField() and xCopyOfField().

• Handling of heterogeneous arrays (type X_FIELD) in xCopyOfField().

Added

• xDestroyLookupAndData() to destroy a lookup table including all the data that was referenced inside it.

Changed

• xCreateField() to treat X_RAW types always as scalars, ignoring the dimensions provided.

[1.0.0] - 2025-03-31

Initial public release.
