forestly vs vcr: at a glance
What is forestly?
forestly built an interactive safety review tool, then taught it to produce submission-ready RTF.
forestly renders adverse-event forest plots as interactive reactable widgets — filterable by AE category, with sliders for incidence thresholds and a toggle for the risk-difference column. Version 0.1.3 added `rtf_static_forestly()` for static RTF output, and 0.1.4 has been about giving the display owner control over what reviewers see: the CSV download button, the AE filter label, and the diff toggle can each be switched off.
What is vcr?
Added the HTTP client everyone moved to, then deleted a decade of its own public surface.
vcr records HTTP interactions to disk so R package tests can replay them without network access. Two releases define its current state. Version 1.6.0 added httr2 support alongside the existing httr and crul backends, following the R ecosystem's migration to httr2. Version 2.0 then removed a large amount of accumulated public surface — the logging functions, vcr_last_error(), the exported R6 classes including RequestHandler, Request, VcrResponse and HTTPInteractionList, and several configuration options that had stopped working or could not be implemented correctly.

forestly built an interactive safety review tool, then taught it to produce submission-ready RTF.
◆ Current state
forestly renders adverse-event forest plots as interactive reactable widgets — filterable by AE category, with sliders for incidence thresholds and a toggle for the risk-difference column. Version 0.1.3 added `rtf_static_forestly()` for static RTF output, and 0.1.4 has been about giving the display owner control over what reviewers see: the CSV download button, the AE filter label, and the diff toggle can each be switched off.
◆ Where it's heading
The arc runs from a fixed interactive widget toward a configurable one with two output modes. Nearly every new argument in the last two releases exists to remove something from the display or relabel it, which suggests the users driving development are producing outputs for others to review under conventions they do not control. The x-axis range, column header, figure header and slider range arguments point the same way — this is a tool being fitted into standardised reporting rather than used ad hoc.
◆ Prediction
Given that the last two releases have consisted almost entirely of display-control arguments, the next is likely more of the same, applied to whichever parts of the interactive layout are still fixed.

0.0ANALYTICS
Added the HTTP client everyone moved to, then deleted a decade of its own public surface.
◆ Current state
vcr records HTTP interactions to disk so R package tests can replay them without network access. Two releases define its current state. Version 1.6.0 added httr2 support alongside the existing httr and crul backends, following the R ecosystem's migration to httr2. Version 2.0 then removed a large amount of accumulated public surface — the logging functions, vcr_last_error(), the exported R6 classes including RequestHandler, Request, VcrResponse and HTTPInteractionList, and several configuration options that had stopped working or could not be implemented correctly.
◆ Where it's heading
The package is consolidating after years of additive growth. The 2.0 removals are almost all things that were exported without needing to be, or options that promised behaviour the implementation could not guarantee — check_cassette_names() was deprecated precisely because it cannot be made correct. Cassette maintenance is being simplified too, with re_record_interval now the single mechanism for expiring recordings.
◆ Prediction
Expect the post-2.0 releases to be about migration support and fallout from the removed API, since the breaking list is long enough that reverse dependencies will surface problems. Async support for httr2 stays blocked until req_perform_parallel gains a mocking hook, which the entries note is upstream work.
