   This is the list of all noteworthy changes made in every public

-### Version ++4.05a (dev)
+### Version ++4.05c (release)
+  - MacOS: libdislocator, libtokencap etc. do not work with modern
+    MacOS anymore, but could be patched to work, see this issue if you
+    want to make the effort and send a PR:
+    https://github.com/AFLplusplus/AFLplusplus/issues/1594
   - afl-fuzz:
     - added afl_custom_fuzz_send custom mutator feature. Now your can
       send fuzz data to the target as you need, e.g. via IPC.
-    - cmplog mode now has -l R option for random colorization, thanks
+    - cmplog mode now has a -l R option for random colorization, thanks
       to guyf2010 for the PR!
     - queue statistics are written every 30 minutes to
-      out/NAME/queue_data - likely this will be moved to a debug flag
-      in the future.
+      out/NAME/queue_data if compiled with INTROSPECTION
+    - new env: AFL_FORK_SERVER_KILL_SIGNAL
   - afl-showmap/afl-cmin
-    - -t none now translates to -t 120000 (120 seconds)
+    - `-t none` now translates to `-t 120000` (120 seconds)
   - unicorn_mode updated
+  - updated rust custom mutator dependencies and LibAFL custom mutator
+  - several minor bugfixes
 
 ### Version ++4.04c (release)
   - fix gramatron and grammar_mutator build scripts

-# argvfuzz
+# argv_fuzzing feature
+AFL++ supports fuzzing file inputs or standard input. The argv_fuzzing feature
+allows for the fuzzing of arguments passed to a program from the command line
+interface rather than from STDIN.  
 
-AFL++ supports fuzzing file inputs or stdin. When source is available,
-`argv-fuzz-inl.h` can be used to change `main()` to build argv from stdin.
+## With source code
+When the source code is available, a specific macro from the `argv-fuzz-inl.h`
+header file can be used to change the program's behavior to build argv from STDIN.
 
+### Without persistent mode
+Conditions needed to use the argv_fuzzing feature:
+1. Include `argv-fuzz-inl.h` header file (`#include "argv-fuzz-inl.h"`)
+2. Identify your main function that parses arguments
+(for example, `int main(int argc, char **argv)`)
+3. Use one of the following macros (near the beginning of the main function)
+to initialize argv with the fuzzer's input:
+   - `AFL_INIT_ARGV();` or
+   - `AFL_INIT_SET0("prog_name");` to preserve `argv[0]`
+   (the name of the program being executed)
+   
+see: [argv_fuzz_demo.c](argv_fuzz_demo.c)
+
+### With persistent mode
+Conditions needed to use the argv_fuzzing feature with persistent mode:
+1. Ensure your target can handle persistent mode fuzzing
+2. Follow instructions in the [llvm_mode persistent mode](https://github.com/AFLplusplus/AFLplusplus/blob/stable/instrumentation/README.persistent_mode.md)
+3. Use one of the following macros near the beginning of the main function and after 
+the buffer initialization (`unsigned char *buf = __AFL_FUZZ_TESTCASE_BUF`):
+   - `AFL_INIT_ARGV_PERSISTENT(buf)`, if you want to 
+   - `AFL_INIT_SET0_PERSISTENT("name_of_binary", buf)`
+
+see: [argv_fuzz_persistent_demo.c](argv_fuzz_persistent_demo.c)
+
+## Binary only
 `argvfuzz` tries to provide the same functionality for binaries. When loaded
 using `LD_PRELOAD`, it will hook the call to `__libc_start_main` and replace
 argv using the same logic of `argv-fuzz-inl.h`.
 
 A few conditions need to be fulfilled for this mechanism to work correctly:
 
-1. As it relies on hooking the loader, it cannot work on static binaries.
+1. As it relies on hooking the loader, it cannot work on static binaries
 2. If the target binary does not use the default libc's `_start` implementation
    (crt1.o), the hook may not run.
-3. The hook will replace argv with pointers to `.data` of `argvfuzz.so`. If the
-   target binary expects argv to be living on the stack, things may go wrong.
