+## 0.4.37
+
+### Minor Analysis Improvements
+
+* The GitHub Actions analysis now recognizes more Bash regex checks that restrict a value to alphanumeric characters, including regexes like `^[0-9a-zA-Z]{40}([0-9a-zA-Z]{24})?$` which check for a SHA-1 or SHA-256 hash. This may reduce false positive results where command output is validated with grouped or optional alphanumeric patterns before being used.
+
+## 0.4.36
+
+### Minor Analysis Improvements
+
+* Altered 2 patterns in the `poisonable_steps` modelling. Extra sinks are detected in the following cases: scripts executed via python modules and `go run` in directories are detected as potential mechanisms of injection. For the go execution pattern, the pattern is updated to now ignore flags that occur between go and the specific command. This change may lead to more results being detected by the following queries: `actions/untrusted-checkout/high`, `actions/untrusted-checkout/critical`, `actions/untrusted-checkout-toctou/high`, `actions/untrusted-checkout-toctou/critical`, `actions/cache-poisoning/poisonable-step`, `actions/cache-poisoning/direct-cache` and `actions/artifact-poisoning/path-traversal`.

+## 0.6.29
+
+### Query Metadata Changes
+
+* Reversed adjustment of the name of `actions/untrusted-checkout/high`, but kept the portion of the previous change for the word "trusted" to "privileged". Added a missing "a" to phrasing in `actions/untrusted-checkout/high` and `actions/untrusted-checkout/medium`.
+
+### Major Analysis Improvements
+
+* Adjusted `actions/untrusted-checkout/critical` to align more with other untrusted resource queries, where the alert location is the location where the artifact is obtained from (the checkout point). This aligns with the other 2 related queries. This will cause the same alerts to re-open for closed alerts of this query.
+
+### Minor Analysis Improvements
+
+* Altered the alert message for clarity for queries: `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`.
+* The `actions/unpinned-tag` query now recognizes 64-character SHA-256 commit hashes as properly pinned references, in addition to 40-character SHA-1 hashes.
+
+### Bug Fixes
+
+* Adjusted (minor) help file descriptions for queries: `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`, `actions/untrusted-checkout/medium`. Clarified wording on a minor point, added one more listed resource and added one more recommendation for things to check.
+
+## 0.6.28
+
+### Query Metadata Changes
+
+* Adjusted the name of `actions/untrusted-checkout/high` to more clearly describe which parts of the scenario are in a privileged context.
+
+### Minor Analysis Improvements
+
+* The `actions/unpinned-tag` query now analyzes composite action metadata (`action.yml`/`action.yaml` files) in addition to workflow files, providing more comprehensive detection of unpinned action references across the entire Actions ecosystem.
+
+### Bug Fixes
+
+* Fixed help file descriptions for queries: `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`, `actions/untrusted-checkout/medium`. Previously the messages were unclear as to why and how the vulnerabilities could occur.

+## 0.6.29
+
+### Query Metadata Changes
+
+* Reversed adjustment of the name of `actions/untrusted-checkout/high`, but kept the portion of the previous change for the word "trusted" to "privileged". Added a missing "a" to phrasing in `actions/untrusted-checkout/high` and `actions/untrusted-checkout/medium`.
+
+### Major Analysis Improvements
+
+* Adjusted `actions/untrusted-checkout/critical` to align more with other untrusted resource queries, where the alert location is the location where the artifact is obtained from (the checkout point). This aligns with the other 2 related queries. This will cause the same alerts to re-open for closed alerts of this query.
+
+### Minor Analysis Improvements
+
+* Altered the alert message for clarity for queries: `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`.
+* The `actions/unpinned-tag` query now recognizes 64-character SHA-256 commit hashes as properly pinned references, in addition to 40-character SHA-1 hashes.
+
+### Bug Fixes
+
+* Adjusted (minor) help file descriptions for queries: `actions/untrusted-checkout/critical`, `actions/untrusted-checkout/high`, `actions/untrusted-checkout/medium`. Clarified wording on a minor point, added one more listed resource and added one more recommendation for things to check.

+## 10.2.0
+
+### Deprecated APIs
+
+* The `UsingAliasTypedefType` class has been deprecated. Use `TypeAliasType` instead.
+
+### New Features
+
+* Added a `getOriginalTemplate` predicate to `TemplateClass`, `TemplateFunction`, `TemplateVariable`, and `AliasTemplateType`, which yields the class member template the template was generated from. The predicates only have results for templates that are members of class template instantiations.
+* Added `AliasTemplateType` and `AliasTemplateInstantiationType` classes, representing C++ alias templates and their instantiations.
+
+### Minor Analysis Improvements
+
+* Added flow source models for `scanf_s` and related functions.
+* Added a `Call` column to `LocalFlowSourceFunction::hasLocalFlowSource` and `RemoteFlowSourceFunction::hasRemoteFlowSource`. The old predicates without a `Call` column continue to be supported.
+
+## 10.1.1
+
+### Minor Analysis Improvements
+
+* The `RemoteFlowSourceFunction` model for `fscanf` (and variants) now implements `hasSocketInput` to reflect that these functions may read from a socket.
+

+## 10.2.0
+
+### Deprecated APIs
+
+* The `UsingAliasTypedefType` class has been deprecated. Use `TypeAliasType` instead.
+
+### New Features
+
+* Added a `getOriginalTemplate` predicate to `TemplateClass`, `TemplateFunction`, `TemplateVariable`, and `AliasTemplateType`, which yields the class member template the template was generated from. The predicates only have results for templates that are members of class template instantiations.
+* Added `AliasTemplateType` and `AliasTemplateInstantiationType` classes, representing C++ alias templates and their instantiations.
+
+### Minor Analysis Improvements
+
+* Added flow source models for `scanf_s` and related functions.
+* Added a `Call` column to `LocalFlowSourceFunction::hasLocalFlowSource` and `RemoteFlowSourceFunction::hasRemoteFlowSource`. The old predicates without a `Call` column continue to be supported.
