Changes include correcting Compatibility rendering's multiply blending, improving XR viewport error messages, and fixes across animation, editor, GDScript, GUI, and imports. The standard build supports GDScript and GDExtension; the .NET build also supports C# and now requires .NET 10 or newer, up from .NET 8. The release is still prerelease software, so the post recommends frequent backups or version control and invites testers to check existing issues before reporting bugs. The excerpt covers changes since beta 1, not the full set of Godot 4.8 changes. ### Source excerpt 4.8's second beta snapshot arrives ## How to Build Interactive Blazor Sunburst Charts for Hierarchical Data DevFeed: [How to Build Interactive Blazor Sunburst Charts for Hierarchical Data]() Original publisher: [Read original article]() Author: Mohammed Nowfel Published: 2026-10-29T11:00:00Z Content type: tutorial Language: en Sources: [Syncfusion]() Topics: [Blazor](), [Data visualization](), [Learning]() Tags: [2026](), [3](), [analysis](), [blazor](), [blazor-charts](), [blazor-charts-data-visualization-productivity-web-what-s-new](), [blazor-data-analytics-dashboard](), [blazor-drill-down-chart](), [blazor-sunburst-chart](), [build](), [charts](), [dashboards](), [data](), [data-visualization](), [data-visualization-in-blazor](), [faster](), [help](), [hierarchical-chart-in-blazor](), [hierarchical-data-visualization-in-blazor](), [how-to](), [insights](), [interactive](), [interactive-sunburst-chart](), [net](), [net-10](), [productivity](), [sunburst-chart](), [syncfusion-blazor-charts](), [users](), [volume](), [web](), [what-s-new](), [with]() ### AI overview Syncfusion's Blazor Sunburst Chart, introduced in the 2026 Volume 3 release, visualizes hierarchy and proportional values in concentric rings, with drill-down and breadcrumb navigation for exploring branches. The guide binds flat records through ID and parent-ID fields, typically assigns values to leaf nodes, and relies on the chart to aggregate parent totals. Setup requires the Syncfusion.Blazor.Charts package (v35.1.37 or later), service registration, namespaces, and a JavaScript reference whose location depends on the Blazor hosting model. It includes a validator for duplicate IDs, missing parents, and cycles, while noting that numeric values and business-specific rules may need separate checks. Production guidance covers realistic performance and label testing, server-side authorization and tenant filtering, accessibility, and deployment checks. For hundreds of categories, limited space, or precise size comparison, the article suggests considering Treemap. ### Source excerpt Simplify hierarchical data analysis with the new Blazor Sunburst Chart in 2026 Volume 3 and build interactive dashboards that help users uncover insights faster. ## Microsoft Releases Out-of-Band .NET Security Updates: Four Vulnerabilities Addressed DevFeed: [Microsoft Releases Out-of-Band .NET Security Updates: Four Vulnerabilities Addressed]() Original publisher: [Read original article]() Author: PravinKarthik Published: 2026-10-26T17:22:12Z Content type: news Language: en Sources: [Cyber Newsroom]() Topics: [.NET](), [Vulnerabilities](), [cve remediation](), [Security](), [ASP.NET](), [Linux]() Tags: [brotli](), [buffer](), [buffer-overflow](), [cve](), [cve-2026-111497](), [cve-2026-114148](), [dotnet](), [microsoft](), [net](), [net-10](), [net-11](), [net-8](), [net-9](), [october](), [oob-patches](), [out-of-band](), [releases](), [security](), [security-updates](), [updates](), [vulnerabilities](), [vulnerability]() ### AI overview Microsoft's October 25, 2026 out-of-band .NET updates address four vulnerabilities, including two fixes that correct issues left unresolved by the October 13 updates. The risks differ by component: Brotli decompression can expose applications processing untrusted compressed data; affected Linux tarball ownership metadata can enable local file modification and privilege escalation; and the corrected SocketAsyncEventArgs fix covers .NET 8-11, while the Blazor WebAssembly debugger issue affects .NET 10-11 and requires updating specific server and dev-server package references. Deploy the applicable patched release (8.0.33, 9.0.22, 10.0.14, or .NET 11 RC3), rebuild self-contained applications and containers, review affected Linux installations, and verify production versions. `dotnet --list-runtimes` checks shared runtimes but does not reveal runtimes bundled with self-contained or NativeAOT applications. .NET Framework is not affected by the described Brotli vulnerability. ### Source excerpt Microsoft Releases Out-of-Band .NET Security Updates: Four Vulnerabilities Addressed Microsoft released out-of-band security updates for .NET on October 25, 2026, outside its regular monthly servicing schedule.The release addresses a buffer overflow vulnerability in Brotli decompressi ...

A malicious compressed stream can cause crashes or memory leaks and may enable remote code execution; the advisory also describes remote privilege escalation on unpatched .NET systems using non-default configurations. Applications are exposed when they opt into ASP.NET Core request decompression or HttpClient automatic response decompression, or invoke .NET Brotli APIs; decompression is not enabled by default. PoC exploits are public, but the excerpt reports no malicious exploitation in the wild. Microsoft advises updating promptly. If patching is delayed, block incoming Brotli-compressed requests through a proxy or firewall, or disable Brotli decoding. Updating the system Brotli library may not protect applications that bundle their own copy. ### Source excerpt Microsoft released emergency .NET security updates to patch a critical vulnerability known as Broccoli2Shell, also tracked as Node2Shell and HTTP2Shell. [...] ## .NET October 2026 Out-of-Band Security Updates DevFeed: [.NET October 2026 Out-of-Band Security Updates]() Original publisher: [Read original article]() Author: Rahul Bhandari (MSFT) Published: 2026-10-25T18:45:00Z Content type: release Language: en Sources: [.NET Blog]() Topics: [.NET](), [Security](), [ASP.NET Core]() Tags: [2026](), [algorithm](), [apis](), [application](), [applications](), [artifacts](), [brotli](), [cve-2026-111497](), [cve-2026-114148](), [maintenance-updates](), [net](), [net-10](), [net-11](), [net-8](), [net-9](), [net-framework](), [october](), [oob](), [out-of-band](), [ownership](), [security](), [security-updates](), [updates](), [vulnerability]() ### AI overview The October 2026 out-of-band updates for .NET 8, 9, and 10 and .NET 11 RC3 address Brotli decoder vulnerability CVE-2026-111497 and Linux tarball ownership vulnerability CVE-2026-114148, and provide fixes for two issues not fully addressed by the October 13 release. Brotli processing may be affected through ASP.NET Core request decompression, HttpClient automatic response decompression, or System.IO.Compression APIs; the two decompression features are off by default, and .NET Framework is unaffected. The tarball issue affects source-build tarballs for .NET 10 and 11, and also ASP.NET Core tarball distributions for .NET 8 and 9. To update, install the targeted runtime and restart framework-dependent apps; rebuild and republish self-contained apps; rebuild and redeploy containers with updated images; or use updated source-build artifacts and rebuild packages. ASP.NET Core tarball users on .NET 8 and 9 should install the refreshed tarball. .NET 11 RC2 users should move to RC3. ### Source excerpt Out-of-band security updates for .NET address the Brotli decoder vulnerability and tarball ownership vulnerability.

It tracks channels such as latest, lts, preview, and daily, resolves them to releases during updates, keeps exact versions pinned, and reads the nearest global.json to support deterministic team builds. It can install supported runtimes individually and removes components no longer required. Access modes range from running .NET through dotnetup to editing shell configuration; Windows-only everywhere mode changes system PATH and requires elevation, and may take precedence over Visual Studio's machine-wide SDKs. Microsoft says commands may change during preview and recommends installers, package managers, or Visual Studio for production machines. Users also raised concerns about the curl-to-shell bootstrap, lack of package-manager options, Visual Studio visibility, and management of other CLI tools; packages are planned after user validation. ### Source excerpt Microsoft has released a public preview of dotnetup, a cross-platform toolchain manager that installs and updates .NET SDKs and runtimes in the user's own directory without admin rights. It tracks channels such as latest, lts, preview, and daily, reads global.json, and removes unused installs. Commands may still change before general availability.

Its concrete example is keyed dependency injection: instead of writing a factory, filtering `IEnumerable`, or using a third-party container to choose between implementations such as Stripe and PayPal, register each implementation with a key and request it by key. The excerpt names TimeProvider, frozen collections, global exception handling, and built-in resilience but provides no details on their use. ### Source excerpt Keyed services, TimeProvider, frozen collections, global exception handling and built-in resilience: five practical upgrades that quietly...

Text payload sizes are roughly comparable to JSON, and actual savings depend on the data. The excerpt contrasts CBOR with Protobuf, which can be highly efficient but requires shared schemas, and MessagePack, which is similar but lacks CBOR's formal IETF standardization and streaming support as described here. In .NET, System.Formats.Cbor provides low-level CborWriter and CborReader APIs: callers write and read primitive values and manage structure themselves rather than automatically mapping objects. The examples cover encoding and decoding maps and arrays, selecting conformance modes such as canonical key ordering, and skipping unknown values for forward compatibility. The author suggests JSON remains suitable for most APIs and points to ASP.NET Core's use of CBOR for compact, application-specific cookie data. ### Source excerpt In this post I introduce CBOR as a JSON alternative, and show how to use the System.Formats.Cbor NuGet package to read and write CBOR encoded data ## Get Your .NET MAUI App Ready for Xcode 27 DevFeed: [Get Your .NET MAUI App Ready for Xcode 27]() Original publisher: [Read original article]() Author: Gerald Versluis Published: 2026-10-19T16:05:00Z Content type: tutorial Language: en Sources: [.NET Blog]() Topics: [.NET MAUI](), [Xcode](), [.NET](), [Agent Skills](), [XcodeGen](), [Continuous Delivery (CD)]() Tags: [activation](), [agent](), [agent-skill](), [agent-skills](), [apple](), [authentication](), [build](), [c-sharp](), [cli](), [code](), [coding-agent](), [command-line](), [content](), [ios](), [lifecycle](), [mac-catalyst](), [net](), [net-10](), [net-for-ios](), [net-maui](), [net-maui-cli](), [net-sdk](), [scene-lifecycle](), [uikit](), [xcode](), [xcode-27]() ### AI overview This tutorial explains how to migrate an existing .NET MAUI app for Xcode 27's UIKit scene lifecycle requirement.
