Amazon RDS for Oracle now supports 19.2 version of Oracle Application Express (APEX) for 11.2, 12.1, 12.2, 18c and 19c versions of Oracle Database. Using APEX, developers can build applications entirely within their web browser. 

VPC Interface endpoints (powered by AWS PrivateLink) and gateway endpoints now support additional IAM condition keys. With this launch, you can now use the IAM condition key ec2: VpceServiceOwner to restrict creation of interface endpoints to either AWS services or services owned by specific AWS accounts. You can also restrict endpoint creation to only specific services by using the ec2: VpceServiceName condition key in your IAM policies. Additionally, you can manage actions on your VPC endpoint and endpoints services based on existing tags on resources like VPCs and subnets using the ec2:resourceTag condition key. 

Amazon DynamoDB global tables are now available in the AWS China (Beijing) Region, operated by Sinnet, and the AWS China (Ningxia) Region, operated by NWCD. With DynamoDB global tables, you can create fully replicated tables across regions for disaster recovery and high availability of your DynamoDB tables. With this launch, you can now add a replica table in one AWS China Region to your existing DynamoDB table in the other AWS China Region. When you use DynamoDB global tables, you benefit from an enhanced 99.999% availability SLA at no additional cost.  

In the past, when submitting an encoding job to an AWS Elemental MediaConvert reserved queue, the job would stay in that queue until it could be processed. If the queue was busy, the job would wait to start until previous jobs completed. This presents a challenge for videos requiring strict turnaround times. To solve this, MediaConvert now has the ability to submit jobs using a feature called queue hopping. You specify the queue a job should start in and how long it should wait before hopping to a different queue. With queue hopping, you can avoid long wait times for transcoding jobs that are time-sensitive while also effectively utilizing your reserved transcoding slots. For example, a job can be submitted to a reserved queue with a wait time of 15 minutes; if the job has not started after that time, it can hop to an on-demand queue to start encoding. For more information about queue hopping, please read the documentation .

AWS Elemental MediaConnect now supports failover between two live sources into a flow. If one source fails, MediaConnect can failover to the second source, increasing the resiliency of live video transport. This provides uninterrupted ingest and transport of live video streams by adding resilience and automatic failover. The SMPTE-2022-7 standard (seamless protection switching at the packet level) is used if the two sources are compliant, otherwise active/active failover is used. To learn more, please visit the MediaConnect User Guide .

You can now launch the T3 instance type with Amazon Neptune for development and test scenarios. Amazon T3 instances are the next generation burstable general-purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required. T3 instances offer a balance of compute, memory, and network resources and are ideal for database workloads with moderate CPU usage that experience temporary spikes in use.
