https://github.com/clj-commons/ordered v1.16.13 - Provides sets and maps that preserve insertion order With thanks to my co-maintainers @nbtheduke & @danielcompton, this https://cljdoc.org/d/org.flatland/ordered/1.16.13/doc/changelog#v1.16.13: • Defines the public API. Because we made internals private, there is a tiny chance this release could be breaking for you. We found no uses of these internals in the wild. Let us know if you have been affected. https://github.com/clj-commons/ordered/issues/98 (@lee) • Adds ClojureScript support for ordered-set: https://github.com/clj-commons/ordered/issues/66 (thanks, https://github.com/marksto!) • Adds ordered-map? and ordered-set? predicates: https://github.com/clj-commons/ordered/issues/102 (https://github.com/lread) • Adds support for contains? and find on transient ordered-map: https://github.com/clj-commons/ordered/issues/69 (https://github.com/NoahTheDuke) • Removes use of resolve in ordered-set. https://github.com/clj-commons/ordered/issues/71 (@nbtheduke) • Fixes bug related to self-referential transient maps: https://github.com/clj-commons/ordered/issues/69 (https://github.com/NoahTheDuke) • Docs reviewed and updated (@lee) • Quality: Increases CI OS & platform coverage, adds linting, automates release workflow (@lee) org.flatland/ordered is one of the many projects under the loving care of https://github.com/clj-commons.

https://github.com/soulspace-org/overarch v0.43.0: Overarch provides a data model for the holistic description of a software system, opening multiple use cases on the model data. Supports C4 and UML diagram generation with PlantUML/GraphViz and template based artifact generation. Main updates: • enable transitive model queries via CLI • added new element types: ◦ :non-goal, :risk and :stakeholder nodes ◦ :decision-for, :non-goal-for, :risk-for and :stakeholder-of relations • all artifacts are now generated via templates See the release notes and change log for further information.

I've also added two skills for creating/editing models and model queries in the .claude/skills folder with reference docs for agents in the agents folder. The AI can generate models from an existing code base and documentation and can query the model as a knowledge graph, which should reduce the context needed for design and coding tasks. Tested with Claude and Copilot.

Released version 0.44.0, which contains relevant fixes and markdown template improvements.

https://github.com/babashka/neil: a CLI to add common aliases and features to deps.edn-based projects See the https://blog.michielborkent.nl/new-clojure-project-quickstart.html blog post for a gentle introduction into neil. 0.3.71 • neil requires babashka 1.13.229 or later • https://github.com/babashka/neil/issues/269: bump deps-new to v0.17.0. neil new requires babashka 1.13.226 or later • https://github.com/babashka/neil/issues/272: make babashka.neil/-main easier to call from code (https://github.com/lread) • https://github.com/babashka/neil/issues/268: neil dep upgrade LIB upgrades only LIB instead of all deps • https://github.com/babashka/neil/issues/267: neil dep add, dep upgrade and dep versions find versions in the :mvn/repos of deps.edn. dep versions no longer lists snapshots • https://github.com/babashka/neil/issues/254: auto-generated CLI help and https://github.com/babashka/neil#shell-completions via babashka.cli. neil dep --help no longer throws • neil test -e excludes tests with the given metadata instead of running only those. neil test --help also prints the help of the test runner • https://github.com/babashka/neil/issues/235: neil dep upgrade keeps the :git/url of a git dep • https://github.com/babashka/neil/issues/249: neil dep add removes the keys of the previous coordinate type, such as :git/sha when it adds :mvn/version • https://github.com/babashka/neil/issues/239: neil dep add no longer throws on metadata on the :deps map. Bump rewrite-edn to 0.6.11 • https://github.com/babashka/neil/issues/250: neil version no longer throws without deps.edn. neil version set, major, minor and patch create it • https://github.com/babashka/neil/issues/237: print the invalid GitHub token warning once per run
