Added optional Operational Insights Dashboard to CloudWatch for monitoring and insights into solution performance
Added support for using multiple EC2 maintenance windows with a single schedule
Added ability to specify KMS keys that Instance Scheduler should be granted permissions to use when starting
EC2 instances with encrypted EBS volumes

Separated "Scheduled Services" parameter into individual enabled/disabled parameters for each supported service
Upgrade Python runtime to 3.11
Extensive refactoring to internal code to improve code quality and testability
CloudWatch metrics feature renamed to "Per Schedule Metrics" and integrated with new Operational Insights Dashboard
DynamoDB Deletion Protection now enabled by default on solution DynamoDB tables.
Refactored maintenance window dynamodb table to be more cost-efficient at scale
Updated schedule logs to include SchedulingDecision entries for all decisions made by the EC2/RDS schedulers.
Scheduler CLI will now error when attempting to overwrite schedules managed by CloudFormation

Configuration settings from CloudFormation parameters no longer duplicated in DynamoDB
Remove deprecated "overwrite" Schedule flag (distinct from still-supported "override" flag)
Cloudwatch Metrics feature replaced with Operational Monitoring

Fixed deployment error in China partition, introduced in v1.5.0
Fixed bug where CloudFormation Schedules used UTC timezone if not specified in template (instead of stack default)
Fixed bug that would cause the scheduling request handler lambda would hang when trying to scheduler more than 50 RDS instances in the same region
Fixed bug that would sometimes cause the CFN schedule custom resource to error when many schedules were deployed in parallel
Fixed bug that would cause spoke stacks to not be correctly deregistered from the hub stack when undeployed
Fixed bug in cli describe_schedule_usage command that would incorrectly estimate the behavior of schedules using nth weekday expressions
Fixed bug that would cause schedules using monthday ranges of the format "n-31" to fail to load in months
with less days then the end of the range (such as February)
Fixed configured_in_stack property not being correctly applied to periods deployed by CloudFormation custom resource.

Break monolith Lambda Function and permissions apart based on principle of least privilege
Spoke stack trust permissions restricted to only specific lambda roles in the Hub account
Allow KMS keys for scheduling encrypted EBS volumes to be specified directly on hub/spoke stacks in cloudformation
rather needing to be added to scheduling roles manually
