SoftEther VPN vs ElevenLabs: at a glance
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 ElevenLabs?
ElevenLabs is rebuilding voice agents as versioned software — branches, drafts, compiles, tests.
ElevenAgents now dominates the changelog, and it ships software-engineering primitives rather than voice features: branches, rebase, merge previews, drafts, and per-test tool mocks. Procedures compile into agent workflows, knowledge bases have crawl jobs and bulk operations, and telephony has widened past Twilio to Exotel and SIP. The speech and music models still advance — Music v2, Speech Engine — but they now read as components sitting under an agent runtime.

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.

ElevenLabs is rebuilding voice agents as versioned software — branches, drafts, compiles, tests.
◆ Current state
ElevenAgents now dominates the changelog, and it ships software-engineering primitives rather than voice features: branches, rebase, merge previews, drafts, and per-test tool mocks. Procedures compile into agent workflows, knowledge bases have crawl jobs and bulk operations, and telephony has widened past Twilio to Exotel and SIP. The speech and music models still advance — Music v2, Speech Engine — but they now read as components sitting under an agent runtime.
◆ Where it's heading
The company is converging on an agent SDLC: author in a branch, hold changes as drafts, preview the merge, compile, then test against mocked tools. Every release adds another step of that loop rather than another voice. The analytics surface — sentiment scoring, termination reasons, backchannel flags, per-branch call volume — is being built to close the same loop with production evidence.
◆ Prediction
With simulations, tool mocks and is_error failure paths now in place alongside branches and merge previews, the missing piece is a gate: expect evaluation runs that block a branch merge on regression rather than leaving testing as a manual step.
