YOUSEFUL / FILEMAKER

Youseful Software branding and upgrades

Effective 2026-09-20, this suite uses Youseful Software as its commercial brand, Youseful in full product names, and Ysfl in file names and FileMaker function prefixes. The product table is the current naming reference.

Upgrade from GF builds

• Replace each GF<Product>.fmx64 with Ysfl<Product>.fmx64. Close FileMaker first and move the previous binary outside its Extensions folder; install only one version of each plug-in.
• Use Ysfl in place of GF for new function calls: for example, GFTx_RegexMatch becomes YsflTx_RegexMatch. Query's earlier YFSL_ prefix becomes YsflQr_. File's current prefix is YsflFi_, including functions formerly documented as YSFL_.
• The four-byte SDK plug-in IDs and numeric function IDs are unchanged to preserve FileMaker's stored references. Old function names are not registered as aliases; update text-based calculations and scripts that construct function names. Verify existing solutions in FileMaker after replacing the binaries.
• New Credential Manager entries use Youseful:<name> and the display user Youseful Software. Existing GreekFire:<name> entries remain accessible for reads, overwrites and deletes. If both exist, the Youseful entry takes priority.
• Runtime configuration uses YSFL_NODE, YSFL_PYTHON and YSFL_PHP. Existing GF_NODE, GF_PYTHON and GF_PHP variables are accepted as fallbacks. Generated host scripts now live in %LOCALAPPDATA%\Youseful\hosts\.
• Encryption, compression and printer-setting serialization markers are unchanged so saved data remains readable.

The parent company's copyright notices, internal C helper names and SDK IDs remain where they describe ownership or compatibility rather than product branding. Vendor source and licenses are unchanged. Dated designs, plans and research in docs/superpowers/ and docs/research/ preserve their historical wording; this document and the current product references supersede their naming.
