What is httr?
httr's last releases are housekeeping - the package now points users at httr2
httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.
What is Rollbar?
Rollbar's AI arc reaches its endpoint: the error tracker now opens the pull request.
Rollbar spent 2026 converting error tracking into an AI workflow, and the Resolve agent is where that lands — production errors now come back as pull requests carrying a fix, test results, and a root cause. The monetization moved with it: AI features bill against a credit pool sold separately from plan tier, with no per-seat charge. Around that core, the platform work has been deliberately unglamorous, covering account-wide API tokens, an MCP server, session replay timelines, and a settings UI rebuild.

◆ Current state
httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.
◆ Where it's heading
This is a succession, not a decline. The maintainers are keeping httr installable and passing checks for the very large base of packages that depend on it, while all design work happens in httr2. The pattern across these six releases is unambiguous: nothing lands here unless CRAN, a test service, or a platform forced it.
◆ Prediction
Expect continued patch releases driven only by CRAN checks and toolchain changes; the interesting HTTP work in R will keep landing in httr2.
Rollbar
6.3DEVOPS
Rollbar's AI arc reaches its endpoint: the error tracker now opens the pull request.
◆ Current state
Rollbar spent 2026 converting error tracking into an AI workflow, and the Resolve agent is where that lands — production errors now come back as pull requests carrying a fix, test results, and a root cause. The monetization moved with it: AI features bill against a credit pool sold separately from plan tier, with no per-seat charge. Around that core, the platform work has been deliberately unglamorous, covering account-wide API tokens, an MCP server, session replay timelines, and a settings UI rebuild.
◆ Where it's heading
The product is moving from telling you what broke to handing you the change that fixes it, and each release since April closed part of that loop — root cause in April, cheap access to it in June, codebase reach via MCP and account tokens in July, code generation and test execution in August. Credits rather than seats are the pricing unit, which lets Rollbar put agent features on the free plan without cannibalizing tier upgrades. Moving code access onto a dedicated GitHub App suggests that reach is now treated as infrastructure rather than an integration.
◆ Prediction
Expect Resolve to exit beta with credit consumption as the primary lever, and the agent to reach past single-error fixes — the cross-project correlation and telemetry already assembled for root cause analysis are the obvious next inputs.
