What is SoftEther VPN?

SoftEther returns after 16 months with Windows ARM64 support and a pile of fixes.

SoftEther 5.2.5189 is the first 5.x release since July 2025. It adds Windows ARM64 support with an ARM64 Neo6 driver, restores kernel-mode NAT, adds a configurable DHCP discover timeout and a Turkish translation, and fixes memory leaks, a dangling pointer and Linux password input. Builds can now disable the post-quantum OQS library added in 5.2.5188.

What is Clair?

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

SoftEther returns after 16 months with Windows ARM64 support and a pile of fixes.

◆ Current state

SoftEther 5.2.5189 is the first 5.x release since July 2025. It adds Windows ARM64 support with an ARM64 Neo6 driver, restores kernel-mode NAT, adds a configurable DHCP discover timeout and a Turkish translation, and fixes memory leaks, a dangling pointer and Linux password input. Builds can now disable the post-quantum OQS library added in 5.2.5188.

◆ Where it's heading

The 5.x line moves slowly and in batches, with community contributors doing most of the work. After 5.2.5188 added hybrid post-quantum key exchange, this release is about platform reach and stability rather than new protocol features.

◆ Prediction

The cadence suggests a long gap before the next tag; the entries give no sign of another protocol-level change soon.

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

◆ Current state

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

◆ Where it's heading

Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.

◆ Prediction

More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
