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 FusionAuth?

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

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.

F2.5

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

◆ Current state

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

◆ Where it's heading

Where the notes are readable, the direction is standards conformance and closing security defaults that were too permissive, accepting breaking changes to do it. FusionAuth has been willing to make an enabled identity provider's linking strategy immutable and to require global API keys where tenant keys used to work — changes that break running deployments in exchange for a tighter default. What cannot be read from this feed is where the last two releases fit, because they shipped without notes.

◆ Prediction

The pattern of hardening endpoint-by-endpoint suggests further scope narrowing wherever tenant-level keys still reach installation-level effects. Any read on 1.68.0 and 1.69.0 would be guesswork — the entries carry no content.
