redb 4.0 Released: XML Routes, Lazy References, Unique Keys and WS-Trust Across the Ecosystem
redb 4.0 delivers a coordinated major release across the entire ecosystem, updating redb.Core, redb.Route, redb.Tsak and redb.Identity in a single 4.0.0 version. Seventy-six NuGet packages, seven container images in GHCR and archives for Windows and Linux are now published. The Pro edition remains free and does not require a license key on the entire 4.x line.
redb.Route receives ten new packages and a substantial engine redesign. Declarative routes can now be defined in .route.xml files using the new redb.Route.Xml package and loaded into the same fluent DSL used for C# routes. The redb.Route.TestKit allows testing without brokers or route modifications through AdviceRoute, MockEndpoints and NotifyBuilder. Additional packages provide Scriban and Liquid templates, CSV, Protobuf, Avro and YAML data formats, JSONata transformations, in-memory or distributed caching, and XPath 2.0 support.
The routing engine now uses a single expression language and compiler for conditions, values and templates. New functions include stats, format, uuid and the modulo operator. The bean component allows custom objects to be used as endpoints with dependency injection. REST DSL, OpenAPI 3.0.3 generation, OpenTelemetry metrics inside routes and removal of Newtonsoft.Json in favour of System.Text.Json are also included.
Hosting improvements cover concurrent request limits with 429 responses, automatic consumer scaling for RabbitMQ, AMQP 1.0, IBM MQ, SQS and MQTT, WebSocket and SignalR support on the shared Kestrel host, and trusted proxy handling for X-Forwarded headers. Kafka consumers now preserve unprocessed records on partition revocation, and connectors for S3, Firebase and LLM providers received multiple stability and feature updates.
redb.Core introduces lazy references that load only on first access to Props when EnableLazyReferences is active, and unique keys via the new ValueUnique mechanism and [RedbUnique] attribute. Unique constraints are enforced by database indexes for scalars, nested objects, collections and entire subtrees. Schema upgrades are applied at startup with typed exceptions when rights are insufficient. CancellationToken support, save interceptors, per-request isolation levels and maintenance operations such as AnalyzeAsync are now available across PostgreSQL, MSSQL and SQLite.
redb.Tsak cluster coordination now relies on unique database keys from redb.Core. XML-only modules can be loaded and reloaded at runtime. The dashboard distinguishes load shedding from idle routes, Audit and Dead-letter pages are functional on PostgreSQL, and trusted proxy configuration is exposed for API throttling.
redb.Identity adds a WS-Trust SOAP facade supporting Issue, Validate, Cancel and Renew operations. Access tokens now include audience claims according to RFC 9068. The administrative console has been rebuilt with full pages instead of dialogs, and DPoP support behind TLS-terminating proxies has been improved.
Several security issues were addressed. Internal headers are now stripped on all three identity facades. Consent pages validate signed tickets and Origin headers. Introspection responses are restricted to token audiences. Dashboard pages require authentication with role-based access. Module signatures are verified on every load path, and the default password hasher is now bcrypt.
Clusters must be fully stopped before upgrading because mixed versions are unsupported. Large databases require a maintenance window for schema changes performed under exclusive locks. Full change logs are published at redb.ru/releases.

Teenage Smartphone Addiction: Causes, Consequences, and Treatment Approaches
Smartphone use has become an integral part of adolescent life, but problematic usage patterns rather than device ownership itself are the focus of concern. Medical experts avoid the term smartphone addiction and instead address issues like disrupted self-control, social media overuse, and gaming disorder that interfere with sleep, studies, relationships, and mental health. Data from Pew Research indicates nearly 50% of U.S. teens aged 13-17 are online almost constantly, while CDC findings link four or more hours of daily screen time to elevated anxiety and depression symptoms. Family digital habits strongly influence teen behavior, and rigid bans often fail without addressing underlying issues such as boredom, anxiety, or social isolation. Parents are advised to track specific disruptions over a week and consider professional help when signs of depression, bullying, or self-harm appear alongside device overuse.
VK WorkSpace Federation Enables Secure Multi-Organization On-Premise Messaging Without Infrastructure Merge
VK Tech has released federation capabilities for its VK WorkSpace corporate messenger that connect independent On-Premise installations while preserving each organization's full control over data, administration, and security policies. The feature, first piloted in November 2025 and expanded in the July 2026 26.2 release, supports multi-party chats across more than two separate environments. Federation relies on mutual trust establishment and per-user access grants rather than full directory replication or proxy access to a single host instance. Each participating organization maintains local copies of messages, files, and chat metadata, allowing continued access even if a partner installation becomes unavailable. The architecture deliberately avoids both centralized hosting and open protocols such as Matrix to keep changes to the existing messenger core minimal. Administrators retain independent levers to create or revoke trusts and to limit which employees may communicate externally.

Client orientation through user experience analysis and personalized solutions ranked second, while operational efficiency via cost reduction, automation, and digitalization took third place.
Russia Hands Down First Conviction Under New Criminal Article for Online Drug Propaganda
A resident of Orenburg became the first person in Russia to receive a criminal sentence under Article 230.3 of the Criminal Code, which criminalizes online drug propaganda following repeated administrative violations. The man was fined 100,000 rubles and had his mobile phone confiscated after he printed and posted leaflets containing a QR code that directed users to job advertisements linked to drug distribution. The scheme began when he was recruited via messenger to place the leaflets for 10 rubles each, without realizing the content involved narcotics-related vacancies. Prior to this case, the individual had already been sanctioned twice within the same year for illegal drug advertising, allowing prosecutors to escalate the matter to the new criminal provision that took effect on 1 March. The court considered his prior record as a recidivism aggravating factor yet imposed the minimum fine after he admitted guilt, expressed remorse, and cooperated with investigators. The ruling has already entered into force, marking the initial application of the statute that permits penalties up to two years of imprisonment or fines between 100,000 and 300,000 rubles.
