What is SoftEther VPN?
Post-quantum key exchange landed, then the release train went quiet.
SoftEther's 5.x line ships infrequently — six tags spread across 2023 to 2025, most of them merge-commit version bumps with no release notes. The one substantive entry in this window, 5.2.5188, folded liboqs and oqs-provider submodule updates in to add X25519MLKEM768, the NIST hybrid post-quantum key exchange. Everything around it is build plumbing: FreeBSD and macOS CI images, Linux artifact publishing, Docker machinery moved into the main repo.
What is Tailscale?
Tailscale is turning the tailnet itself into something a script provisions and pages through.
Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.

SoftEther VPN

Post-quantum key exchange landed, then the release train went quiet.
◆ Current state
SoftEther's 5.x line ships infrequently — six tags spread across 2023 to 2025, most of them merge-commit version bumps with no release notes. The one substantive entry in this window, 5.2.5188, folded liboqs and oqs-provider submodule updates in to add X25519MLKEM768, the NIST hybrid post-quantum key exchange. Everything around it is build plumbing: FreeBSD and macOS CI images, Linux artifact publishing, Docker machinery moved into the main repo.
◆ Where it's heading
The work is drifting from protocol features toward build and supply-chain hygiene, and the crypto addition arrived through submodule updates rather than in-house design. Release notes are thin enough that several tags credit contributors without describing what changed. With the newest entry now over a year old, this reads as a maintenance-paced project carried by a small group of contributors.
◆ Prediction
If the pattern holds, the next tag is another accumulation of CI and dependency work, with post-quantum defaults tightening as liboqs moves upstream. The entries give no signal of a new protocol or management-plane direction.

6.3INFRA · APIS
Tailscale is turning the tailnet itself into something a script provisions and pages through.
◆ Current state
Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.
◆ Where it's heading
Tailscale has spent this period on two different customers at once. The operator work serves platform teams running Tailscale inside Kubernetes, where the gaps being closed are reconciliation loops, stale DNS ConfigMaps and cert-renewal backoff. The tailnet API work serves a different shape entirely: organizations holding enough tailnets that a hundred is a page boundary, which only happens when tailnets are allocated per customer or per environment rather than per company. The second thread is the one that changes what Tailscale is for.
◆ Prediction
Pagination on list implies the creation API is being used at volume, so expect the alpha to gain the management operations a fleet needs — policy templating or bulk configuration across tailnets. The client release line looks settled on 1.102.x maintenance in the near term.
