# Update the html_text variable with the latest DataTables CDN links
# To update:
# 1. Visit https://datatables.net/download/index
# 2. Select all default options except "Extensions"
# 3. At the bottom of the page, click the "CDN" panel
# 4. Choose "Minified" but not "Concatenated"
# 5. Copy the entire CDN panel content
# 6. Replace the html_text variable below with the copied content
#
# Note: This ensures we always have the most up-to-date DataTables resources
# while maintaining a consistent structure for our download process.

version = "2.1.4" # this must be the same as the version in the html_text
