Nextcloud, a European software vendor, has raised concerns about Google's treatment of its Android Files application, which has over 800,000 users. The issue centers on the "All files access" permission, which was revoked by the Play Store in 2024, impairing the app's functionality. Nextcloud argues that alternatives like the Storage Access Framework (SAF) and MediaStore API are inadequate for their needs. The app has been able to read and write all file types since its launch in 2016 without security concerns from Google until the recent revocation. Nextcloud claims that Google's policies are stifling competition and that they have faced bureaucratic inefficiencies in addressing their complaints. Despite having a fully functional version on F-Droid, the Google Play version is restricted. Nextcloud has previously lodged a complaint with the EU regarding Microsoft's anti-competitive behavior, and they express frustration over the lack of action taken. They believe larger tech companies are trying to suppress smaller competitors.

On April 29, 2025, Jepsen released a report on transaction visibility behavior in Amazon RDS for PostgreSQL and its Multi-AZ clusters, which has been acknowledged since at least 2013. The report identifies a Long Fork anomaly affecting the visibility order of transactions between primary and replica nodes in cluster configurations, which does not lead to data loss or corruption and is absent in Single-AZ deployments. This anomaly allows two readers to see transactions in different sequences, breaching Snapshot Isolation. It affects all isolation levels in community PostgreSQL and can also occur in self-managed deployments. The issue has been discussed extensively in the PostgreSQL community, and potential solutions, including synchronizing visibility with commit order using Commit Sequence Numbers, have been proposed. AWS has established the PostgreSQL Contributors Team to address this anomaly and enhance PostgreSQL's capabilities.

Microsoft has acknowledged a significant issue affecting enterprise users trying to upgrade to Windows 11 24H2 via Windows Server Update Services (WSUS) after installing the April 2025 security updates, specifically the monthly security update KB5055528. Users with Windows 11 23H2 or 22H2 are encountering Windows Update Service errors with the code 0x80240069, preventing the download process for Windows 11 24H2 from initiating or completing. Microsoft confirmed that devices with the April security update might be unable to update via WSUS. WSUS, primarily used in enterprise settings, has been deprecated as of September 2024, but Microsoft will continue to support existing functionalities. Additionally, Microsoft is addressing a "latent code issue" that has caused some devices to upgrade to Windows 11 despite Intune policies against such upgrades.

TencentDB for PostgreSQL has introduced robust security measures including data encryption, Virtual Private Cloud (VPC) isolation, and process monitoring for compliance with international standards. PostgreSQL 17.0 features enhanced logical replication with slot failover, performance optimizations such as batch I/O page read/write and improved Write-Ahead Logging, and operational enhancements like incremental backups and a transaction timeout parameter. Tencent has developed features for resource management, including fine-grained multi-tenant resource management with CPU resource isolation and process-level monitoring, as well as SQL throttling. Cold/hot data separation solutions include the 'cos_fdw' plugin for accessing cold data and the 'starocks_fdw' plugin for integrating with the StarRocks analytics engine. Security auditing has been improved with an Express Edition for basic needs and an Advanced Edition for broader audit coverage. These enhancements aim to balance performance and cost, maximize resource efficiency, and strengthen compliance.

Windows users previously faced challenges using Linux tools via virtual machines until the introduction of the Windows Subsystem for Linux (WSL), which was further improved with WSL2. WSL2 integrates a lightweight virtual machine into Windows, allowing users to run Linux applications seamlessly. Runtipi and CasaOS can be easily set up on WSL2 to host self-service applications without complex configurations. Visual Studio Code (VS Code) offers a WSL extension that enables code execution directly in Linux distributions from Windows, enhancing the coding experience. Gigolo is a frontend for managing network shares, which can also be integrated into Windows 11 through WSL2. Ansible can automate the provisioning of virtual machines and containers on WSL2, making it easier for users engaged in DIY projects. Rsync can be installed via WSL2 for efficient file synchronization and backups on Windows. Podman Desktop allows Windows users to explore container runtimes using WSL2, providing a GUI for managing containers. Lastly, WSL2 enables users to access the Linux terminal and run various Linux distributions directly within Windows 11.

Microsoft has reported that two recent updates for Windows 11 24H2, specifically the April cumulative update KB5055523 and the March preview update KB5053656, are causing blue screen crashes with the error code 0x18B (SECUREKERNELERROR) after installation and reboot. There is currently no permanent solution, but Microsoft is working on a workaround using a Known Issue Rollback (KIR) that will automatically apply to personal or unmanaged devices through Windows Update. IT departments will need to manually download a Group Policy .msi file to implement the rollback. Affected machines will require a restart to complete the process.
