eratosthenes vs SoftEther VPN: at a glance
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
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.

◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.
SoftEther VPN
0.0INFRA · APIS
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.
