Stirling-PDF deepens real signing and lays MCP groundwork on a fast V2 cadence

pdfself-hosteddocument-signingmcprelease-cadence
◆Current state
Stirling-PDF is in a heavy release cadence on its V2 line, alternating substantive minors with rapid hotfixes. The last month shipped desktop hardware-token signing (PKCS#11/smart-card and OS cert stores), a work-in-progress MCP page, JDK 25 enforcement, and large merge-memory improvements, punctuated by Postgres and desktop-signing hotfixes.
◆Where it's heading
Two threads stand out: deepening real document signing (hardware tokens, shared signing, cert-store integration) and laying agent-facing groundwork via an MCP page and automation-oriented backend work. The team is also steadily reworking the V2 file-management UI that users found clunky. This is a self-hosted PDF tool maturing toward serious signing and automation use.
◆Prediction
Expect the MCP page to move from WIP toward a usable agent interface, and the signing feature set to broaden beyond desktop-only.
