Fixed font package detection for fonts with spaces in their names (e.g., "Noto Emoji", "DejaVu Sans"). Previously, latexmk() failed to automatically install the missing font package because the search pattern preserved the space, but font files never have spaces in their names (thanks, @cderv, #478, #479).

Added detection for PDF/A errors and automatic installation of the latex-lab package when \DocumentMetadata support files are missing (thanks, @cderv).

Added the colorprofiles, latex-lab, and pdfmanagement-testphase packages to the TinyTeX bundle to better support PDF/A document compilation (thanks, @cderv, @gordonwoodhull, #481, #482).

Support TeX Live on macOS when symlinks are installed to /Library/TeX/texbin (a standard MacTeX-style installation), so that users no longer need to manually adjust PATH.

TinyTeX prebuilt binaries are now provided for ARM64 Linux (aarch64) (thanks, @edavidaja, #483).

TinyTeX prebuilt binaries are now provided for x86_64 musl Linux (Alpine Linux and other musl-based distributions), so Docker/Alpine users can install TinyTeX with a fast binary download instead of a slow source build (#485, #487).

The TinyTeX release binary naming scheme has been updated to TinyTeX-{N}-{os}[-{arch}].{ext} (e.g., TinyTeX-1-linux-x86_64.tar.xz, TinyTeX-1-linux-arm64.tar.xz, TinyTeX-1-darwin.tar.xz). Old-style names remain available as backward-compatible copies (#484).

install_tinytex() and install-bin-unix.sh now automatically detect and use the new naming scheme for versions after 2026.03.02, and fall back to the old naming for older versions.

The default CTAN repository is now https://tlnet.yihui.org (a CDN-based mirror hosted on Cloudflare). If this is not accessible, the installer falls back to https://mirror.ctan.org.

The Windows installation scripts (install-windows.bat and install-bin-windows.bat) have been rewritten in PowerShell; the .bat files are now thin wrappers that download and run the corresponding .ps1 scripts (#492, #493).

Suppress spurious warnings from tlmgr_version() when tlmgr cannot be executed (rstudio/rmarkdown#2612).

On macOS, TinyTeX now uses /etc/paths.d/TinyTeX to add the TinyTeX binary directory to PATH when /usr/local/bin is not writable, instead of recursively changing the ownership of /usr/local/bin. The previous behavior (using tlmgr path add) is preserved for users who have already made /usr/local/bin writable. This fixes a filesystem security issue (thanks, @r2evans, #463, #489).
