The autdior published the results on 17 October 2016. QuarksLab conducted an audit of version 1.18 on behalf of the Open Source Technology Improvement Fund (OSTIF), which took 32 man-days.
RAM encryption for keys and passwords on 64-bit systems was added in version 1.24. 
Erasing the system encryption keys from RAM during shutdown/ reboot helps mitigate some cold boot attacks, added in version 1.24. Option to enable/disable support for the TRIM command for both system and non-system drives was added in version 1.22. VeraCrypt added the capability to boot system partitions using UEFI in version 1.18a. 
Unicode passwords are supported on all operating systems since version 1.17 (except for system encryption on Windows). Linux also received support for the NTFS formatting of volumes. Linux and macOS users benefit from support for hard drives with sector sizes larger than 512. The developers added support for SHA-256 to the system boot encryption option and also fixed a ShellExecute security issue. #HOW TO USE VERACRYPT ON MAC WINDOWS#
A vulnerability in the bootloader was fixed on Windows and various optimizations were made as well. The primary downside of this feature is that it makes the process of opening encrypted archives even slower. Veracrypt out of the box uses a reasonable PIM value to improve security, but users can provide a higher value to enhance security. Additionally, since version 1.12, a new feature called "Personal Iterations Multiplier" (PIM) provides a parameter whose value is used to control the number of iterations used by the header key derivation function, thereby making brute-force attacks potentially even more difficult. While these default settings make VeraCrypt slower at opening encrypted partitions, it also makes password-guessing attacks slower. For standard containers and other partitions, VeraCrypt uses 655,331 iterations of RIPEMD160 and 500,000 iterations of SHA-2 and Whirlpool by default (which is customizable by user to be as low as 16,000). While TrueCrypt uses 1,000 iterations of the PBKDF2- RIPEMD160 algorithm for system partitions, VeraCrypt uses either 200,000 or 327,661 iterations by default (which is customizable by user to be as low as 2,048), depending on the algorithm used. This was fixed in VeraCrypt in January 2016. #HOW TO USE VERACRYPT ON MAC DRIVER#
An independent security audit of TrueCrypt released 29 September 2015 found TrueCrypt includes two vulnerabilities in the Windows installation driver allowing an attacker arbitrary code execution and privilege escalation via DLL hijacking. VeraCrypt is still capable of opening and converting volumes in the TrueCrypt format. The VeraCrypt development team considered the TrueCrypt storage format too vulnerable to a National Security Agency (NSA) attack, so it created a new format incompatible with that of TrueCrypt. The user can customize it to start as low as 2,048. By default they go through 200,000 to 655,331 iterations, depending on the underlying hash function used. It generates the header key and the secondary header key (XTS mode) using PBKDF2 with a 512- bit salt. VeraCrypt's block cipher mode of operation is XTS. 
The cryptographic hash functions available for use in VeraCrypt are RIPEMD-160, SHA-256, SHA-512, Streebog and Whirlpool. For additional security, ten different combinations of cascaded algorithms are available: Version 1.19 stopped using the Magma cipher in response to a security audit. VeraCrypt employs AES, Serpent, Twofish, Camellia, and Kuznyechik as ciphers.
