Database Activity Streams (DAS) for Amazon Relational Database Service (Amazon RDS) for Oracle provides a near real-time stream of all audited statements (SELECT, DML, DDL, DCL, TCL) executed in your DB instance. The audit data is collected from the unified database audit, while the storage and processing of database activity is managed outside your database. This prevents database users and administrators from modifying the audit stream.

Amazon Textract is a machine learning service that automatically extracts text, handwriting and data from scanned documents that goes beyond simple optical character recognition (OCR) to identify, understand, and extract data from forms and tables. We continuously improve the underlying machine learning models based on customer feedback to provide even better accuracy. Today, we are pleased to announce an accuracy enhancement update to our forms extraction feature. Starting today, Textract more accurately detects the checkboxes and key-value pairs within documents and images. The accuracy is especially improved for invoices and receipts, but customers will see improvements across many documents in finance, healthcare, legal, public sector, and more.

Amazon CodeGuru Reviewer is a developer tool that leverages automated reasoning and machine learning to detect potential defects that are difficult to find in your code and offers suggestions for improvements. Today, we are announcing a new CI/CD experience for CodeGuru Reviewer that allows you to trigger code quality and security analysis as a step within your CI workflow using GitHub Actions. Additionally, we are also introducing 20+ new detectors for CodeGuru Reviewer to help identify security vulnerabilities and check for security best practices in your Java code.  

You can now simplify the process of configuring GitHub Actions workflows for building serverless applications with a single line. The new AWS-supported setup-sam GitHub Action makes it easier to keep consistency across GitHub Actions runners, stay up-to-date with AWS Serverless Application Model CLI (AWS SAM CLI) tooling, and select its versions. The AWS SAM CLI is a developer tool that makes it easier to build, locally test, package, and deploy serverless applications. GitHub Actions is a service that helps automate tasks within the software development lifecycle. GitHub Actions runner is the application that runs a job from a GitHub Actions workflow.

Amazon Redshift, a fully-managed cloud data warehouse, now supports case-insensitive collation with column and expression level overrides. Starting today, you can use the COLLATE clause within a CREATE DATABASE statement to specify the default collation for all CHAR and VARCHAR columns in the database as case-sensitive or case-insensitive. You can also specify a COLLATE clause in a CREATE TABLE statement to specify collation for columns in that table. In addition, the COLLATE() function allows you to override the collation of a string column or an expression.

Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. Amazon DocumentDB makes it easy and intuitive to store, query, and index JSON data.

You can now specify up to 30 EC2 instance types for each of your master, core, and task node groups when using EMR Instance Fleets with allocation strategy. Previously, this was limited to 15 for tasks nodes, and only 5 for master and core nodes. This increase allows you to specify a broader range of instance sizes, generations, and families that your workloads can operate across to improve your access to both Spot and On-Demand capacity.

You can now use Tax Registration Numbers (TRN) as an additional filter for mapping your purchase orders to your invoices with AWS Purchase Order Management. AWS Purchase Order Management allows you to easily manage your purchase orders (POs) in a self-service manner, define PO-invoice association rules, track PO balance and expiration, and receive email alerts for POs approaching expiration or running out of balance.

You can now build serverless applications with new AWS-supported container images that simplify continuous integration tasks. Container images work natively with continuous integration systems such as CloudBees CI/Jenkins, GitLab CI/CD, GitHub Actions, CircleCI, and AWS CodeBuild. These make it easier to build and package serverless applications using Serverless Application Model CLI (AWS SAM CLI) – a developer tool that makes it easier to build, locally test, package, and deploy serverless applications.
