eratosthenes vs Vault
A side-by-side editorial comparison of eratosthenes and Vault — release velocity, themes, recent moves, and the top alternatives to consider.
eratosthenes vs Vault: 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 Vault?
Vault under IBM lands 2.0.0, with FIPS 140-3 and HSM enterprise builds inside two weeks.
Vault crossed 2.0.0 in late March under its post-HashiCorp / IBM stewardship — the artifact pages now carry IBM's International Program License Agreement language alongside the existing MPL 2.0 / BSL terms. Enterprise variants followed within days: 2.0.0 enterprise FIPS 140-3 and HSM-flavored builds published April 1 and April 8, plus an sdk/v0.25.1 backport addressing a Go CVE. The recent shipping is release-engineering-heavy, not feature-heavy.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
◆ 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.
Vault
2.5INFRA · APISDEVOPS
Vault under IBM lands 2.0.0, with FIPS 140-3 and HSM enterprise builds inside two weeks.
◆ Current state
Vault crossed 2.0.0 in late March under its post-HashiCorp / IBM stewardship — the artifact pages now carry IBM's International Program License Agreement language alongside the existing MPL 2.0 / BSL terms. Enterprise variants followed within days: 2.0.0 enterprise FIPS 140-3 and HSM-flavored builds published April 1 and April 8, plus an sdk/v0.25.1 backport addressing a Go CVE. The recent shipping is release-engineering-heavy, not feature-heavy.
◆ Where it's heading
This is the cadence of a project completing a major-version rollout — community GA first, then RC and GA enterprise-flavor builds, then security-tracking SDK backports — rather than a roadmap pivot. The fact that FIPS 140-3 and HSM enterprise builds shipped in the same window as the 2.0 cycle is the signal worth holding onto: Vault's federal and regulated-industry posture is being kept intact under the new owner, and auth plugin version bumps suggest the wider ecosystem is staying in step.
◆ Prediction
Expect 2.x feature-bearing minor releases over the next few months, with FIPS 140-3 and HSM enterprise variants tracked alongside the community builds. GA bumps for the auth plugins to match the 2.x line are likely. Worth watching for more visible IBM branding or any Cloud-side packaging shifts that signal repositioning under the new owner.
