The detailed list of changes is available at https://github.com/openfheorg/openfhe-development/pulls?q=is%3Apr+milestone%3A%22Release+1.1.1%22

• Adds scheme switching between CKKS and FHEW/TFHE
• Adds comparison and (arg)min evaluation in CKKS via scheme switching to FHEW/FHEW
• Implements a new FHEW/TFHE bootstrapping method proposed in https://eprint.iacr.org/2022/198 (EUROCRYPT'23)
