Release highlights
This is a major release that brings the dependency stack up to date. The public CloudBridge API is unchanged — most users will not need any code changes. The version bump reflects the breadth of the underlying modernization rather than interface breakage.
What users should know
Python 3.13 or higher is now required. Support for older Python versions, including 2.7 compatibility shims (six), has been removed. Earlier Python versions are no longer tested; the default test environment is Python 3.13.
Azure public IPs now use the Standard SKU. Basic-SKU public IPs are being retired by Azure. Public IPs created by CloudBridge are now Standard SKU. Within a single virtual network, public IPs of different SKUs cannot be mixed (Azure restriction). If you have a network that already contains Basic-SKU IPs created by CloudBridge 3.x, plan to standardize on one SKU before letting 4.0 add new IPs to that network.
Mock provider now requires moto >= 5.0. If you use MockAWSCloudProvider in your own test suite alongside direct moto usage, your test harness must be on moto 5. In moto 5, the per-service decorators (mock_ec2, mock_s3, …) were unified into a single mock_aws.
If you pin cloud SDKs alongside CloudBridge, you may need to relax upper bounds. The biggest jumps: azure-mgmt-compute (up to <39), azure-mgmt-network (<31), openstacksdk (<5).
Under the hood (no action required)
CloudBridge migrated off several abandoned Azure libraries (msrestazure, azure-cosmosdb-table, pysftp) and onto their maintained successors. The migration is transparent at the API level. Existing Azure resources created by 3.x — including key pairs stored in Azure Table Storage — are read by 4.0 without migration.
