+## [0.7.0] - 26-08-2025
+
+### Changed
+
+* Serialization: Move all variable-length items to end of encoding
+  (GP [#418](https://github.com/gavofyork/graypaper/pull/418))
+* Rearrange the items in `CoreActivityRecord` and `ServiceActivityRecord`,
+  refer to the ASN.1 schema and GP (no explicit GP PR).

-## State Transition Functions
-
-We offer two types of test vectors:
-
-- **Tiny**: designed for quick adjustments and prototyping, with reduced
-  - validators count: 6
-  - cores count: 2
-  - epoch period: 12
-  - core assignment rotation period: 4
-  - ticket attempts: 3
-
-- **Full**: vectors with production specs
-  - validators count: 1023
-  - cores count: 341
-  - epoch period: 600
-  - core assignment rotation period: 10
-  - ticket attempts: 2
-
-For more information refer to the community [docs](https://docs.jamcha.in/basics/chain-spec).
-
-### STF Output
-
-Technically, the STF execution process does not inherently produce auxiliary
-outputs beyond the success or failure result. In this context, we propose
-an extension to include additional information that may be beneficial for
-implementors or useful for executing other subsystems reliant on values
-generated post-STF execution.
-
-When the error or success values are not pertinent to your test vector
-processing procedures, you may disregard them as necessary.
-
-A mapping of error code semantics is provided within the ASN.1 schema for each
-specific subsystem.

+The repository binary test vector files can be converted to their JSON

+script to transform binary files into human-readable JSON format:
 
-## Block Import Traces
+```bash
+./scripts/convert-all.sh
+```
 
-- [Fallback](./traces/fallback): fallback block authoring, no-safrole, no-work-reports
-- [Safrole](./traces/safrole): safrole block authoring, no-work-reports
-- [Work Reports L0](./traces/reports-l0): basic work reports, no-safrole
+This script requires the [jam-types](https://github.com/davxy/jam-types-py)
+Python library to be installed.
 
-## Vectors Validation
+## Validation
 
 Validation scripts are included to verify the JSON files against the expected
 ASN.1 syntax provided with the test vectors. These scripts currently rely on my
 [asn1tools](https://github.com/davxy/asn1tools) fork.
