Download the signed DH20.01 release

DH20.01 maps to technical package DCSF 15.10.4. The public bootstrap accepts only this exact signed release and its closed artifact inventory.

DCSF

What the release contains

The installer, signed update manifest, public verification key, package digest and release identity are published together.

Signed package

The 15.10.4 archive is bound by digest to the signed manifest.

Verification

The bootstrap pins the RSA-3072 key, signature, SHA-256, size and closed file inventory.

Release identity

DH20.01 maps unambiguously to technical DCSF version 15.10.4.

Security register

All 51 security fixes and three operational controls are verified, completing all 54 gates in the release matrix.

DCSF

Three supported installation paths

The bootstrap identifies the server state before changing installed files and does not treat an upgrade as a fresh installation.

Fresh installation

Requires an explicit --testing or --production profile. The recommended first run uses --testing.

DCSF upgrade

The installer detects the current version, refuses downgrades and asks before an upgrade or same-version reinstall.

Migration from cpanel-csf

It authenticates and preflights the complete package first, then asks for approval. After confirmation it creates a private configuration and firewall backup, checks the rollback source, removes the cPanel RPM and installs DCSF.

Released

The signed public package and installer are available.

For a fresh installation, start with --testing. For an upgrade, run the script without a profile flag to preserve the existing TESTING value and answer the installer prompt.
