Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of accessr and Auth0 — release velocity, themes, recent moves, and the top alternatives to consider.
One R Markdown source, four accessible formats — and a fortnight spent patching around someone else's bug.
accessr turns a single R Markdown file into HTML slides, HTML, Word and PDF output, with an emphasis on producing documents a screen reader can navigate. Accessible PDFs come via OfficeToPDF and are Windows-only, which is the package's main structural constraint. Recent releases have been spent absorbing and then unwinding a fault in the officedown dependency.
Auth0 hands tenants a throttle on their own noisy apps
Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.
accessr turns a single R Markdown file into HTML slides, HTML, Word and PDF output, with an emphasis on producing documents a screen reader can navigate. Accessible PDFs come via OfficeToPDF and are Windows-only, which is the package's main structural constraint. Recent releases have been spent absorbing and then unwinding a fault in the officedown dependency.
The package's own development is focused on the details that make output genuinely accessible rather than merely produced — PDF bookmarks generated from Word headings, image dimension handling, header behaviour in slide output. That work is intermittent, and the more visible pattern in 2025 is dependency fragility: a CRAN check failure traced to a strsplit() call inside officedown forced a temporary patch, which was reverted two weeks later once upstream fixed it. Depending on a chain of document-conversion tools means the package inherits their breakages.
The next release will likely be another response to an upstream document-tooling change, though the pdf_args work suggests further OfficeToPDF options could be exposed if accessibility gaps surface.
Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.
Two threads dominate. One is agent and delegation infrastructure — Agents as Principal, Token Vault Privileged Worker, Custom Token Exchange session delegation — all still in Early Access. The other is tenant self-service: rate limits, blocklists, organization search and roles, global search. Auth0 is systematically converting things that required support intervention into API-configurable policy.
The Early Access items now stacking up, particularly the agent-identity pieces, are the obvious GA candidates next, following the Flexible Password Policy path from Early Access to general availability.
