# Status

## 2026-04-29

* *GitBook*: New [Outreach](/safe-clean-architecture/appendices/outreach.md) article — [What if your pattern matching could call functions?](/safe-clean-architecture/appendices/outreach/active-patterns.md) — covering F# Active Patterns illustrated with Shopfoo examples

## 2026-04-14

* *Shopfoo*: Apply `[<CallerMemberName>]` in `IInstructionPreparer` extension methods
* *GitBook*: Update [Program Runner](/safe-clean-architecture/domain-workflows/2-program.md#auto-deriving-instruction-names-with-callermembername) and [Api](/safe-clean-architecture/domain-workflows/3-domain-workflow/4-api.md)

## 2026-03-30

* *GitBook*: New [Outreach](/safe-clean-architecture/appendices/outreach.md) section in Appendices — lists LinkedIn posts promoting the GitBook

## 2026-03-25

* *GitBook*: New [Pattern Variations](/safe-clean-architecture/domain-workflows/2-program/pattern-variations.md) addendum — compares Free Monad and Tagless Final implementation variations (John Azariah's approaches, gitbook V3/V3bis/V4), covering instruction typing, parallelism, combinators, and turnkey vs generic design
* *GitBook*: Update [Algebraic Effects](/safe-clean-architecture/domain-workflows/1-introduction/4-algebraic-effects.md) page — note that V3bis variant enables parallelism in the Free Monad

## 2026-03-12

* ✅ GitBook complete
* ✅ Shopfoo complete, [release 1.4.1](https://github.com/rdeneau/shopfoo/releases/tag/v1.4.1) deployed\
  💡 Eventual improvements:
  * [ ] Integrate and document Playwright
  * [ ] Migrate to .NET 10, Fable 5 (currently in [RC](https://fable.io/blog/2026/2026-02-27-Fable_5_release_candidate.html)), Feliz v3

## 2026-02-10

* *Shopfoo*: Start implementing the [Saga support](/safe-clean-architecture/domain-workflows/2-program.md#saga-support-undo) execution mode for the `Program`, enabling undo of completed instructions when a workflow fails

## 2026-02-07

* *Shopfoo*: Start migrating the `Program` (used in [domain workflows](/safe-clean-architecture/domain-workflows/2-program.md)) to v4—TagLess Final pattern—to support parallel instruction execution
* The last version of *Shopfoo* code with Program v3 is available via the [`program-v3`](https://github.com/rdeneau/shopfoo/tree/program-v3/) tag

## 2025-12-31

* Write [Motivations](/safe-clean-architecture/motivations.md)
* Publish *Shopfoo* [version 1.2](https://github.com/rdeneau/shopfoo/releases/tag/v1.2.0): complete any feature "under construction" (displayed with the 🚧 emoji). There are still some features to implement - see [README.md#features](https://github.com/rdeneau/shopfoo/tree/main#features)

## 2025-12-20

* Announcing the start of writing this book, as an entry to the [F# Advent Calendar in English 2025](https://sergeytihon.com/2025/11/03/f-advent-calendar-in-english-2025/) – Thank you, Sergey Tihon 🙏
* *Shopfoo* is functional and deployed for the playground. Some features are missing and the code can be improved. Still, the code can be explore in preview if needed.
