v0.31.0 - 2025-09-27

Changed

• Upgraded quick-xml to v0.38. This was a significant change in quick-xml
  relative to v0.37 and required changes in calamine to entity handling. It
  also fixes EOL handling which may lead to regressions in calamine
  applications if they expected to see "\r\n" in strings instead of the
  correct (for XML and Excel) "\n".

  For most users these will be inconsequential changes but please take note
  before upgrading production code.

• Renamed the "dates" feature flag to "chrono" since there is now some
  native date handling features without "chrono". The "chrono" flag is more
  specific and accurate. The "dates" flag is still supported as before for
  backward compatibility.

  This change also made some datatype methods related to date/times available in
  the "default" feature set. They were previously hidden unnecessarily behind
  the "dates/"chrono" flag.

Added

• Added a conversion function to ExcelDateTime to convert the inner serial
  Excel datetime to standard year, month, date, hour, minute, second and
  millisecond components. Works for 1900 and 1904 epochs.

Fixed

• Fixed issue where Excel xlsx shared formula failed if it contained Unicode
  characters. Issue #553.

• Fixed issue where Excel XML escapes in strings weren't unescaped. For example
  "_x000D_" -> "\r". Issue #469.
