## 5.3.0
|
||||
|
||||
### Deprecated APIs
|
||||
|
||||
* The `UnknownDefaultLocation`, `UnknownExprLocation`, and `UnknownStmtLocation` classes have been deprecated. Use `UnknownLocation` instead.
|
||||
|
||||
### New Features
|
||||
|
||||
* Added a `isFinalValueOfParameter` predicate to `DataFlow::Node` which holds when a dataflow node represents the final value of an output parameter of a function.
|
||||
|
||||
### Minor Analysis Improvements
|
||||
|
||||
* The `FunctionWithWrappers` library (`semmle.code.cpp.security.FunctionWithWrappers`) no longer considers calls through function pointers as wrapper functions.
|
||||
* The analysis of C/C++ code targeting 64-bit Arm platforms has been improved. This includes support for the Arm-specific builtin functions, support for the `arm_neon.h` header and Neon vector types, and support for the `fp8` scalar type. The `arm_sve.h` header and scalable vectors are only partially supported at this point.
|
||||
* Added support for `__fp16 _Complex` and `__bf16 _Complex` types
|
||||
* Added `sql-injection` sink models for the Oracle Call Interface (OCI) database library functions `OCIStmtPrepare` and `OCIStmtPrepare2`.

### Minor Analysis Improvements
|
||||
|
||||
* Due to changes in the `FunctionWithWrappers` library (`semmle.code.cpp.security.FunctionWithWrappers`) the primary alert location generated by the queries `cpp/path-injection`, `cpp/sql-injection`, `cpp/tainted-format-string`, and `cpp/command-line-injection` may have changed.
|
||||
* Added flow models for the Win32 API functions `CreateThread`, `CreateRemoteThread`, and `CreateRemoteThreadEx`.
|
||||
* Improved support for dataflow through function objects and lambda expressions.
|
||||
* Added flow models for `pthread_create` and `std::thread`.
|
||||
* The `cpp/incorrect-string-type-conversion` query no longer alerts on incorrect type conversions that occur in unreachable code.
|
||||
* Added flow models for the GNU C Library.
|
||||
* Fixed a number of false positives and false negatives in `cpp/global-use-before-init`. Note that this query is not part of any of the default query suites.
|
||||
* The query `cpp/sql-injection` now can be extended using the `sql-injection` Models as Data (MaD) sink kind.
|
||||
|
||||
## 1.4.3
|
||||
|

### Minor Analysis Improvements
|

## 1.4.4
|
||||
|
||||
### Minor Analysis Improvements
|
||||
|
||||
* Due to changes in the `FunctionWithWrappers` library (`semmle.code.cpp.security.FunctionWithWrappers`) the primary alert location generated by the queries `cpp/path-injection`, `cpp/sql-injection`, `cpp/tainted-format-string`, and `cpp/command-line-injection` may have changed.
|
||||
* Added flow models for the Win32 API functions `CreateThread`, `CreateRemoteThread`, and `CreateRemoteThreadEx`.
|
||||
* Improved support for dataflow through function objects and lambda expressions.
|
||||
* Added flow models for `pthread_create` and `std::thread`.
|
||||
* The `cpp/incorrect-string-type-conversion` query no longer alerts on incorrect type conversions that occur in unreachable code.
|
||||
* Added flow models for the GNU C Library.
|
||||
* Fixed a number of false positives and false negatives in `cpp/global-use-before-init`. Note that this query is not part of any of the default query suites.
|
||||
* The query `cpp/sql-injection` now can be extended using the `sql-injection` Models as Data (MaD) sink kind.
