GitHub vs rerddap: at a glance
What is GitHub?
GitHub is shipping models into Copilot weekly while quietly modernizing the OAuth platform underneath
Two rhythms run through GitHub's feed. Copilot absorbs a new frontier model roughly every few days — Grok 4.6 and Gemini 3.7 Flash both landed this week — on top of a weekly release digest covering editors, CLI and the Copilot app, and Agent Plugins 1.0 making a plugin portable across compatible agent clients. Separately, the developer platform gets security and administration work: OAuth apps can opt into expiring access tokens with refresh, rulesets gain an organization-level insights dashboard, license data is now sourced from package registries, and personal repositories allow blocking directly from a comment.
What is rerddap?
An ERDDAP client steadily lowering the cost of pulling large oceanographic extracts
rerddap fetches gridded and tabular data from ERDDAP servers into R. The recent releases follow one practical thread — making large extracts cheaper to move — alongside routine robustness work on error messages and failure modes. 1.3.0 brings parquet output to `griddap()` and adds a function that estimates a download's size before the request is made.

GitHub is shipping models into Copilot weekly while quietly modernizing the OAuth platform underneath
◆ Current state
Two rhythms run through GitHub's feed. Copilot absorbs a new frontier model roughly every few days — Grok 4.6 and Gemini 3.7 Flash both landed this week — on top of a weekly release digest covering editors, CLI and the Copilot app, and Agent Plugins 1.0 making a plugin portable across compatible agent clients. Separately, the developer platform gets security and administration work: OAuth apps can opt into expiring access tokens with refresh, rulesets gain an organization-level insights dashboard, license data is now sourced from package registries, and personal repositories allow blocking directly from a comment.
◆ Where it's heading
The model additions have become routine enough that they read as inventory management rather than direction — Copilot's position is now to carry whichever reasoning model a developer wants, and the differentiation has moved to the surrounding agent surface, where plugin portability and persistent memory are the actual bets. The platform work points the other way, toward closing the long tail of OAuth-era assumptions: opt-in token expiry is the kind of change that only matters once app authors have somewhere to migrate to. Enterprise Server 3.22 is in candidates, which is where the Copilot administration controls consolidate for self-hosted customers.
◆ Prediction
Expect the weekly model cadence to continue without much signal in any individual addition, and the OAuth token expiry to move from opt-in toward default once adoption data supports it. The Agent Plugins ecosystem is the thread worth watching, since its value depends on clients GitHub does not control.

An ERDDAP client steadily lowering the cost of pulling large oceanographic extracts
◆ Current state
rerddap fetches gridded and tabular data from ERDDAP servers into R. The recent releases follow one practical thread — making large extracts cheaper to move — alongside routine robustness work on error messages and failure modes. 1.3.0 brings parquet output to `griddap()` and adds a function that estimates a download's size before the request is made.
◆ Where it's heading
Parquet support has propagated across the package one function at a time: introduced for `tabledap()` in 1.2.0 where the maintainer reports up to 90% smaller files for large extracts, patched in 1.2.3, and extended to `griddap()` in 1.3.0. The size-estimation function added alongside it addresses the same problem from the other end, letting a user find out what a request will cost before committing to it. Around this, the package has absorbed the usual CRAN-driven hardening, notably making all external resource requests fail gracefully.
◆ Prediction
Expect the remaining data-access paths to converge on the same parquet-plus-pre-flight-estimate pattern, since that is how the last three feature releases have each extended it. The entries do not indicate work beyond data retrieval.
