Fast and Portable Character String Processing Facilities

stringi has spent two years on build hardening since its Unicode 15.1 reset.

unicodeicubuild-portabilitystring-processingr-packagemaintenance
◆Current state
stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.
◆Where it's heading
The package has reached feature stability and is maintained as infrastructure. Releases arrive when a toolchain, platform, or check regime changes, not when users ask for capability. The two-and-a-half year gap between 1.8.1's Unicode bump and anything comparable suggests the next directional move will again be an ICU bundle refresh rather than new API surface.
◆Prediction
The next release is most likely another build-time fix or an ICU bundle update to a newer Unicode version; the entries show no in-progress feature work.

◆Recent moves

    Configure script drops the C++11 fallback

    Build hygiene only: warnings cleaned up and the configure script no longer falls back to C++11, tidying up after the compiler floor 1.8.1 established. Nothing changes for callers.

    PROTECT stack imbalance fixed in stri_encode_from_marked

    A memory-management bug in stri_encode_from_marked and more build warnings cleared. Real correctness work at the C level, but invisible from R.

    Windows build errors fixed

    A Windows-only build failure resolved with help from outside contributors. Portability upkeep in the same vein as the rest of the post-1.8.1 window.

    Format-string warnings cleared

    Compiler warnings about non-literal format strings silenced. Check-farm maintenance with no user-facing effect.

    32-bit Windows and Loongarch builds restored

    Three build fixes: a missing Windows API call on 32-bit, flag ordering in configure to match Makevars, and restored ICU double-conversion support on Loongarch. Platform breadth maintained, capability unchanged.

    ICU 74.1 bundle lands; Solaris support dropped

    ⚡ SPARK

    The one release in this window that moves the package rather than maintaining it: a new ICU bundle, a dropped platform, a raised compiler floor, and changed date-time parsing defaults. Everything after it is cleanup on the foundation it laid.
