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.

What is Svelte?

SvelteKit 3 reaches release candidate: breaking changes are frozen and the migration path is open

SvelteKit 3 has moved from preview to release candidate, with the team signalling no further breaking changes before stable. Configuration now lives in vite.config.ts instead of svelte.config.js, and an `sv@next migrate sveltekit-3` codemod handles most of the upgrade automatically while flagging the rest as a TODO list. The 2.x line kept shipping through the same period - remote form `submitted`, a relocated `defineEnvVars`, and zero-config error page props.

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.

SvelteKit 3 reaches release candidate: breaking changes are frozen and the migration path is open

◆ Current state

SvelteKit 3 has moved from preview to release candidate, with the team signalling no further breaking changes before stable. Configuration now lives in vite.config.ts instead of svelte.config.js, and an `sv@next migrate sveltekit-3` codemod handles most of the upgrade automatically while flagging the rest as a TODO list. The 2.x line kept shipping through the same period - remote form `submitted`, a relocated `defineEnvVars`, and zero-config error page props.

◆ Where it's heading

The major is arriving as a consolidation rather than a rewrite: most of what lands in 3.0 was previewed in the 2.x line first, so the upgrade cost stays low by design. The centre of gravity has been remote functions and forms for six straight months, and Kit 3 mostly finalises that surface while pruning the configuration story. With breaking changes now frozen, the work shifts from designing the major to getting the ecosystem - adapters, language tools, community plugins - onto it.

◆ Prediction

The stable SvelteKit 3 release is the next milestone, and the team has tied it to RC feedback rather than a date. Expect the monthly digests to fill with adapter and tooling updates catching up to the vite.config.ts requirement before that lands.
