What is piecepackr?

A board game graphics package runs one of the most disciplined deprecation cycles in R.

piecepackr renders game pieces — piecepack, chess, dominoes and related systems — as 2D grid graphics, 3D meshes, animations, and print-and-play PDFs. Its interface is mature enough that most releases are about managing change rather than adding capability: features get deprecated with a named replacement, live through a release or two, then get removed on schedule. The current release completes the cycle opened a year earlier, retiring the new_device and style arguments in favour of open_device and the composable font, border, background_color and edge_color set.

What is sd2r?

Local Stable Diffusion inference lands in R, shipped as Rcpp bindings over stable-diffusion.cpp

sd2r is a young project wrapping stable-diffusion.cpp for R via Rcpp. The 0.1.0 release established the package structure and the core call surface — sd_ctx(), sd_txt2img(), sd_save_image() — with Vulkan GPU support behind a configure flag and a worked SD 1.5 example at 512x512. The two releases since are not code but asset bundles: precompiled tokenizer vocabularies and BPE merge tables shipped as header files, growing from four tokenizers to twelve.

A board game graphics package runs one of the most disciplined deprecation cycles in R.

◆ Current state

piecepackr renders game pieces — piecepack, chess, dominoes and related systems — as 2D grid graphics, 3D meshes, animations, and print-and-play PDFs. Its interface is mature enough that most releases are about managing change rather than adding capability: features get deprecated with a named replacement, live through a release or two, then get removed on schedule. The current release completes the cycle opened a year earlier, retiring the new_device and style arguments in favour of open_device and the composable font, border, background_color and edge_color set.

◆ Where it's heading

Two things dominate the log. The first is that deprecation discipline, unusually explicit for a package this size — every removal names its successor, and deprecations announced in one release are removed in a predictable later one. The second is defensive dependency management: version bumps pinned around bugs introduced upstream in rayrender and rayvertex, a warning class for known-buggy cairo versions with an option to suppress it, and suggested packages required for metadata embedding with clear messages when they are absent. Functionality still arrives — vectorised 3D object export that finally handles composite pieces, new crosshair grobs, a reworked colour palette — but it arrives inside that maintenance rhythm rather than driving it.

◆ Prediction

The features deprecated in this release — the preview_layout component and the 4x6 print-and-play size — are on the established path toward removal in a future version, with the documented ppdf-based replacement already in place.

Local Stable Diffusion inference lands in R, shipped as Rcpp bindings over stable-diffusion.cpp

◆ Current state

sd2r is a young project wrapping stable-diffusion.cpp for R via Rcpp. The 0.1.0 release established the package structure and the core call surface — sd_ctx(), sd_txt2img(), sd_save_image() — with Vulkan GPU support behind a configure flag and a worked SD 1.5 example at 512x512. The two releases since are not code but asset bundles: precompiled tokenizer vocabularies and BPE merge tables shipped as header files, growing from four tokenizers to twelve.

◆ Where it's heading

The asset releases are the more revealing half of this history. The first bundle covered CLIP, Mistral, Qwen and UMT5 — enough for SD 1.x through Flux. The second adds T5, Gemma, Gemma2 and GPT-OSS merges and splits UMT5 out as the Wan video encoder, so the tokenizer surface now reaches well beyond the image models the package currently exposes. Vocabulary support is being staged ahead of the inference paths that would use it.

◆ Prediction

Given that tokenizers for Flux, SD3 and the Wan video encoder are already bundled while the documented API stops at txt2img, the next step is most likely exposing those model families through the R interface.
