hydroloom vs piecepackr: at a glance
What is hydroloom?
USGS puts a type system over its river network toolkit so errors surface at dispatch
hydroloom builds and navigates hydrologic flow networks, carrying functionality migrated out of nhdplusTools. Version 1.2.0 introduces an S3 class hierarchy — hy_topo, hy_leveled, hy_node, hy_flownetwork — assigned automatically by hy() and by producer functions, letting the package validate input at dispatch time and emit guided errors. Outlet detection is now defined explicitly: a row is an outlet when its toid is not in id, with reserved values, NA and implicit absence all accepted.
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.

◆ Current state
hydroloom builds and navigates hydrologic flow networks, carrying functionality migrated out of nhdplusTools. Version 1.2.0 introduces an S3 class hierarchy — hy_topo, hy_leveled, hy_node, hy_flownetwork — assigned automatically by hy() and by producer functions, letting the package validate input at dispatch time and emit guided errors. Outlet detection is now defined explicitly: a row is an outlet when its toid is not in id, with reserved values, NA and implicit absence all accepted.
◆ Where it's heading
The package spent its first releases porting and broadening — non-dendritic network support, divergence routing, subsetting that follows diversions out of a basin — and has now turned to making that surface safe to use. The class hierarchy is the structural expression of that turn: instead of every function re-checking whether a data frame has the columns it needs, the type carries the guarantee. The explicit outlet rule resolves a category of failure where valid networks errored on NA or orphan toid values.
◆ Prediction
The release notes flag that subclass attributes are stripped by standard dplyr operations, which is the kind of rough edge that usually generates follow-up work — expect attribute preservation or restoration helpers next.

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.
