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 pgBackRest?

pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.

pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

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.

P5.0

pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.

◆ Current state

pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

◆ Where it's heading

Two currents continue. Support for the next PostgreSQL major arrives experimentally a full release before it is needed — 18 in 2.55.0, 19 in 2.59.0, and now tracking 19's betas point by point — so the backup tool is ready before the database ships. The second is a move away from ambient privilege and toward cloud-native identity: managed identities and pod identity in place of stored keys, and the root restriction narrowing what a compromised invocation can reach. The 2.59.1 fixes are the ordinary cost of that pace, including a packaging fault in the GitHub source archives.

◆ Prediction

Expect the beta-tracking patches to continue through PostgreSQL 19's release cycle, with the next feature release arriving after 19 goes final rather than before it.
