What is performance?

performance keeps adding ways to check a model you have already fitted.

performance is at 0.17.1, which added check_priors() for prior predictive checks on Bayesian models and gave check_overdispersion(), check_model() and check_predictions() arguments to control residual type and plot range. The releases before it are a similar mix: a -2LL criterion column in test_likelihoodratio(), Bayesian predictive checks routed through modelbased, and in 0.16.0 a set of breaking renames including RMSA to the correct RMSR.

What is RStudio?

RStudio ships through release branches, and the notes are commit messages

RStudio's feed is a run of release-branch tags — Yellow Yarrow, Pacific Dogwood, Golden Wattle — each carrying a backported fix rather than an announced feature. The newest tag restores a Windows install rule that had been deleted alongside an unrelated winpty block, leaving the shipped installer without a 32-bit rsession binary and breaking 32-bit R entirely. What reaches users is legible only if you read the commit body.

performance keeps adding ways to check a model you have already fitted.

◆ Current state

performance is at 0.17.1, which added check_priors() for prior predictive checks on Bayesian models and gave check_overdispersion(), check_model() and check_predictions() arguments to control residual type and plot range. The releases before it are a similar mix: a -2LL criterion column in test_likelihoodratio(), Bayesian predictive checks routed through modelbased, and in 0.16.0 a set of breaking renames including RMSA to the correct RMSR.

◆ Where it's heading

Two consistent habits. Diagnostics keep gaining arguments to narrow what is examined — ppc_range, x_limits, maximum_dots, show_ci — which reads as a package being used on models large and awkward enough that the defaults stopped working. And simulated residuals via DHARMa keep displacing standard ones as the basis for the checks themselves.

◆ Prediction

With check_priors() newly added and Bayesian predictive checks now routed through modelbased, the next release most likely extends the Bayesian diagnostic set rather than reworking the frequentist checks.

RStudio ships through release branches, and the notes are commit messages

◆ Current state

RStudio's feed is a run of release-branch tags — Yellow Yarrow, Pacific Dogwood, Golden Wattle — each carrying a backported fix rather than an announced feature. The newest tag restores a Windows install rule that had been deleted alongside an unrelated winpty block, leaving the shipped installer without a 32-bit rsession binary and breaking 32-bit R entirely. What reaches users is legible only if you read the commit body.

◆ Where it's heading

Two areas absorb nearly all the visible work: Windows packaging correctness and Posit Assistant plumbing — SHA-256 verification of assistant downloads, gating .positai/.claude ignore-file edits on the directories actually existing. Both read as cleanup after features landed elsewhere. The release-branch structure means the same fix often appears twice, once on main and once backported, so tag count overstates the pace of change.

◆ Prediction

Expect further Yellow Yarrow tags in the same shape — a single backported fix per tag, its description written for reviewers rather than users. Posit Assistant integration is the most likely source of the next visible change, since it is the only area here still gaining behavior rather than losing bugs.
