What is distributions3?
distributions3 0.3.0 adds sample-based distributions and likelihood derivatives
An R package giving probability distributions a consistent object interface - d/p/q/r functions, moments, and prodist() methods that pull a fitted distribution out of a regression object. Version 0.3.0 is the first substantive release under Achim Zeileis's maintenance, and it widens what a distribution is allowed to be: Empirical() represents a distribution by a random sample rather than by parameters, and numerical fallbacks now fill in cdf(), pdf(), quantile(), random() and the moments for any object that implements only some of them. New score() and hessian() generics compute first and second derivatives of the log-likelihood with respect to the parameters, analytically for a few distributions and numerically for the rest.
What is Kameleoon?
Kameleoon refines its prompt-driven personalization editor with widget, targeting, and PBX upgrades.
Kameleoon is iterating on the new Personalization editor and the prompt-based workflow that sits inside it. Recent changes: a simpler two-step widget event creation flow that ties directly to Kameleoon goals, the ability to reorder personalization targeting rules from the new editor, and PBX prompt-area improvements (resizable prompt area, image paste as input). Survey widgets get a configurable response-recording trigger.

◆ Current state
An R package giving probability distributions a consistent object interface - d/p/q/r functions, moments, and prodist() methods that pull a fitted distribution out of a regression object. Version 0.3.0 is the first substantive release under Achim Zeileis's maintenance, and it widens what a distribution is allowed to be: Empirical() represents a distribution by a random sample rather than by parameters, and numerical fallbacks now fill in cdf(), pdf(), quantile(), random() and the moments for any object that implements only some of them. New score() and hessian() generics compute first and second derivatives of the log-likelihood with respect to the parameters, analytically for a few distributions and numerically for the rest.
◆ Where it's heading
Growth used to arrive as new distribution families contributed from outside - the extreme-value set, Erlang, later the Poisson binomial. This release changes the axis: alongside two new distributions it adds an inference layer (score, hessian) and a forecast-evaluation one (crps() methods against scoringRules), which are capabilities about distributions rather than more of them. Dependency weight is being cut at the same time, with ggplot2 demoted to Suggests and glue replaced by base R sprintf().
◆ Prediction
With numeric fallbacks and the derivative generics in place, expect analytic score() and hessian() methods to be filled in across more of the distribution catalogue. The constructor-default change is the likeliest source of follow-up fixes, since calls like Poisson() now return a length-zero distribution where they previously errored.
Kameleoon
1.3ANALYTICS
Kameleoon refines its prompt-driven personalization editor with widget, targeting, and PBX upgrades.
◆ Current state
Kameleoon is iterating on the new Personalization editor and the prompt-based workflow that sits inside it. Recent changes: a simpler two-step widget event creation flow that ties directly to Kameleoon goals, the ability to reorder personalization targeting rules from the new editor, and PBX prompt-area improvements (resizable prompt area, image paste as input). Survey widgets get a configurable response-recording trigger.
◆ Where it's heading
The product is settling into the new editor as the default surface and accumulating the small ergonomics wins teams expect from a mature personalization tool — fewer clicks, fewer manual IDs, more control over evaluation order. The PBX prompt updates suggest AI-assisted variant creation is becoming a more prominent workflow, with multimodal input now supported.
◆ Prediction
Expect the editor's PBX surface to keep gaining capability — likely brand-context awareness, reusable prompts, and broader image-driven generation. Targeting and goal flows will continue to consolidate so users don't need to reach for IDs or admin pages.
