What is cpp11?
cpp11 has spent two years rebuilding itself on R's supported API surface
cpp11 is the header-only C++ interface for R packages, and nearly every release in this window is governed by one force: R core's tightening of what counts as non-API. 0.5.0 removed the growable-vector internals that made push_back() cheap, 0.5.3 and 0.5.4 removed further non-API usage, and the small releases in between are crash and compiler-warning fixes.
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.

cpp11 has spent two years rebuilding itself on R's supported API surface
◆ Current state
cpp11 is the header-only C++ interface for R packages, and nearly every release in this window is governed by one force: R core's tightening of what counts as non-API. 0.5.0 removed the growable-vector internals that made push_back() cheap, 0.5.3 and 0.5.4 removed further non-API usage, and the small releases in between are crash and compiler-warning fixes.
◆ Where it's heading
The package is trading a little performance for the right to keep passing CRAN checks indefinitely, and saying so plainly in the release notes. With R >= 4.0 now required, whole compatibility branches have been deleted rather than maintained. The remaining work is narrow: finish the non-API migration, then get back to interface features like cpp_source() handling multiple files.
◆ Prediction
Expect the last non-API dependencies to be cleared and the deprecated compatibility defines to be removed outright; the entries suggest maintenance discipline rather than new C++ surface.
Rollbar

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.
