+
+Hi Effecters!
+
+Welcome back to This Week In Effect (**TWIE**) - your weekly update of the latest developments in the Effect community and ecosystem.
+
+Effect is a powerful TypeScript library that helps developers build complex, synchronous, and asynchronous programs. One key feature that sets Effect apart is how it leverages structured concurrency to provide features such as async cancellation and safe resource management, making it easier to build robust, scalable, and efficient programs.
+
+To get started, below you’ll find links to our documentation and our guide for installing Effect. Enjoy!

+## Technology
+
+### Effect v4 Beta updates
+
+The v4 beta wrapped up May and opened June with a focused week on observability, Schema robustness, and HTTP credential handling — here are the most notable changes that landed in `effect-smol`.
+ 
+- **Observability (OTLP)**: Added a layer to configure OTLP with standard environment variables, changed OTLP resource attribute precedence for better compatibility with OpenTelemetry collectors, and cleaned up OTLP config internals.
+
+- **Schema improvements**: Refactored `Schema.Error` and `Schema.Defect` for cleaner internals, memoized error and defect schemas by options to avoid redundant instantiation, fixed `Schema.Defect` JSON encoding for `Error` values whose `message` property is not a string, validated `StructWithRest` index signatures, and preserved `Redacted` options in schema representations. Also added a GUID schema filter and max UUID support, and fixed uppercase max UUID validation.
+
+- **Workflow & RPC**: Aligned `Workflow.make` with the `Rpc` style for API consistency across durable execution primitives.
+
+- **HTTP**: Fixed `HttpApi` bearer/HTTP credential decoding to correctly strip space delimiters, and exposed `customFetch` config for Scalar.
+
+- **Redis**: Fixed Redis script handling for the rate limiter.
+
+- **CLI**: Added `-v` as an alias for the `--version` flag.
+
+- **Documentation**: Refined JSDoc usage guidance, and clarified `Schema.Class` equality docs.
+
+Full changelog in the [effect-smol repository](https://github.com/Effect-TS/effect-smol).
