## Version 0.63.0

### Additions

* C#: support ellipsis in declarations ([#3720](https://github.com/semgrep/semgrep/pull/3720))

### Fixes

* Hack: improved support for metavariables ([#3716](https://github.com/semgrep/semgrep/pull/3716))
* Dataflow: Disregard type arguments but not the entire instruction

### Changes

* Optimize ending ... in pattern-insides to simply match anything left

## Version 0.62.0

### Additions

* OCaml: support module aliasing, so looking for List.map will also find code that renamed List as L via module L = List.
* Add help text to sarif formatter output if defined in metadata field.
* Update shortDescription in SARIF formatter output if defined in metadata field.
* Add tags as defined in metadata field in addition to the existing tags.

### Fixes

* core: fix parsing of numeric literals in rule files
* Java: fix the range and autofix of Cast expressions ([#3669](https://github.com/semgrep/semgrep/issues/3669))
* Generic mode scanner no longer tries to open submodule folders as files ([#3701](https://github.com/semgrep/semgrep/pull/3701))
* pattern-regex with completely empty files ([#3705](https://github.com/semgrep/semgrep/issues/3705))
* \--sarif exit code with suppressed findings ([#3680](https://github.com/semgrep/semgrep/issues/3680))
* Fixed fatal errors when a pattern results in a large number of matches
* Better error message when rule contains empty pattern

### Changes

* Add backtrace to fatal errors reported by semgrep-core
* Report errors during rule evaluation to the user
* When and-ed with other patterns, pattern: $X will not be evaluated on its own, but will look at the context and find $X within the metavariables bound, which should be significantly faster
