This release also includes smaller improvements and bugfixes.

Breaking change: Use OS-specific classpath separator to split jvm_args
Feature: Add support to "autofuzz" targets without the need to manually write fuzz targets
Feature: Add macOS and Windows support
Feature: Add option to generate coverage report
Feature: Support multiple hook annotations per hook method
Feature: Support hooking internal classes
Feature: Add sanitizer for insecure deserialization
Feature: Add sanitizer for arbitrary reflective calls
Feature: Add sanitizer for expression language injection
Feature: Provide Jazzer and Jazzer Autofuzz docker images
Feature: Add a stand-alone replayer to reproduce findings
API: Add reportFindingFromHook(Throwable finding) to report findings from hooks
API: Add guideTowardsEquality(String current, String target, int id) and guideTowardsContainment(String haystack, String needle, int id) to guide the fuzzer to generate more useful inputs
API: Add consume(FuzzedDataProvider data, Class<T> type) to create an object instance of the given type from the fuzzer input
API: Add multiple autofuzz() methods to invoke given functions with arguments automatically created from the fuzzer input
Fixed: Prevent dependency version conflicts in fuzzed application by shading internal dependencies
Fixed: Make initialized this object available to <init> AFTER hooks
Fixed: Allow instrumented classes loaded by custom class loaders to find Jazzer internals

This release also includes smaller improvements and bugfixes.

Breaking change: The static fuzzerTestOneInput method in a fuzz target now has to return void instead of boolean. Fuzz targets that previously returned true should now throw an exception or use assert.
Fixed: jazzer wrapper can find jazzer_driver even if not in the working directory
Fixed: Switch instrumentation no longer causes an out-of-bounds read in the driver
Feature: assert can be used in fuzz targets
Feature: Coverage is now collision-free and more fine-grained (based on JaCoCo)
API: Added pickValue(Collection c) and consumeChar(char min, char max) to FuzzedDataProvider
API: Added FuzzerSecurityIssue* exceptions to allow specifiying the severity of findings
