v2.2.0

• Fixed: A blank first line in a CSV or XLSX no longer becomes the header row, which silently truncated the import to a single column
• Fixed: XLSX files whose first worksheet is not sheet1.xml now import correctly — the sheet is resolved through the workbook relationships instead of being assumed (affected files exported by LibreOffice, Google Sheets, and workbooks with reordered or deleted sheets)
• Fixed: XLSX cells that omit the optional r cell-reference attribute no longer collapse an entire row onto its first column
• Fixed: Exported CSV files now start with a UTF-8 BOM so accented values open correctly in Excel instead of being mangled
• Fixed: The "No value" fallback now resolves the preceding column correctly on fields with nine or more columns, where Gravity Forms skips input indices that are multiples of ten
• Fixed: The wrong-file-type message in the form editor now mentions CSV and XLSX; the previous implementation hooked a filter the Chained Selects add-on never applies, so the override never took effect
• Fixed: The form editor script no longer throws when fieldSettings.chainedselect has not been registered yet, which aborted the rest of the inline setup
• Fixed: The frontend choice cache is now actually delivered to the page. Gravity Forms renders forms through gform_pre_render before wp_enqueue_scripts runs and caches the result, so the inline data had nothing to attach to and the cache never shipped — every chained select fell back to a server round trip on each column. The data is now held and flushed once the script is registered
• Improved: Choice export streams row by row instead of building the entire expanded combination set in memory first, so large fields no longer exhaust memory
• Improved: Frontend script exits immediately on pages with no chained select instead of polling for six seconds, and the jQuery $.post interception is only installed when a chained select is actually present
• Improved: Failed GitHub update checks are cached for 30 minutes, so a rate-limited or unreachable API no longer retries a 15-second request on every admin page load
• Security: Capability and nonce checks now run before the uploaded file is opened and parsed
• Security: The XLSX parser restores libxml global state after parsing instead of leaving entity loading and error handling altered for the rest of the request
• Fixed: The per-column unique value limit is now measured on the sanitized values that actually reach the choice tree, so whitespace variants no longer inflate the count
