* *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

## 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

## 2026-02-07

* *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
