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 Storyblok?
Storyblok is layering AI, workflow automation, and enterprise governance on its headless CMS core.
Storyblok continues to ship at a steady clip across three coherent axes: AI-assisted authoring (custom AI tokens, model bring-your-own, folder-level AI translations, usage-based AI Credits), workflow primitives (FlowMotion, Release Merging, Content Calendar), and enterprise governance (SSO/non-SSO role mixing, finer permissions, accessibility refactors). The most recent batch is dominated by enterprise-shaped depth — accessibility passes done with external auditors, SSO role flexibility, security alignment between API and UI access controls.

eratosthenes

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.
Storyblok
4.6INFRA · APIS
Storyblok is layering AI, workflow automation, and enterprise governance on its headless CMS core.
◆ Current state
Storyblok continues to ship at a steady clip across three coherent axes: AI-assisted authoring (custom AI tokens, model bring-your-own, folder-level AI translations, usage-based AI Credits), workflow primitives (FlowMotion, Release Merging, Content Calendar), and enterprise governance (SSO/non-SSO role mixing, finer permissions, accessibility refactors). The most recent batch is dominated by enterprise-shaped depth — accessibility passes done with external auditors, SSO role flexibility, security alignment between API and UI access controls.
◆ Where it's heading
Storyblok is making the case that headless CMS shouldn't mean DIY workflow — by shipping FlowMotion as a first-class capability rather than relying on integrations, it's positioning closer to the Contentful/Sanity tier on operations while keeping its developer-first roots. Parallel investment in AI primitives (BYO model, credits, translations) suggests the product wants to be the substrate other AI workflows orchestrate against.
◆ Prediction
Expect FlowMotion to deepen with templates, conditional logic, and tighter ties to AI translation/generation features — the natural shape is content-ops automation that combines AI generation steps with human review gates. Continued enterprise hardening (audit logs, more granular SSO scenarios) is likely as Storyblok pushes deeper into enterprise CMS deals.
