Twilio’s 2026 Heightened Awareness Period: Ensuring Reliable Messaging for Peak Season
Twilio has scheduled two 2026 Heightened Awareness Periods (HAPs) to manage messaging throughput during U.S. midterm election traffic and the Black Friday/Cyber Monday and holiday shopping surge. During these windows, high-volume short code and toll-free traffic shifts temporarily to Market Throughput, while 10DLC remains on Account-Based Throughput and RCS uses standard per-sender limits; contracted limits are honored. Most users need no action, but election senders should contact their account team by October 1, 2026, and holiday senders face deadlines for RCS approval, throughput review, A2P 10DLC requests, and supplementary orders. The election HAP runs November 2–4, 2026, while the holiday HAP runs November 19, 2026, through January 4, 2027; capacity is limited and allocated first come, first served.
Full Linux VMs for your agents
BoxCompute VM Sandboxes are now the default runtime for every account, giving agents a full Linux virtual machine rather than a shared-kernel gVisor container. Each disposable VM boots its own kernel and provides root access, outbound internet with public IPv4 and DNS, and a unified approximately 10 GiB filesystem covering / and /workspace, while preserving the existing create, execute, file-transfer, and delete API. The CLI or HTTP API can create a VM, and users can opt out with vmSandbox: false or disable networking with blockNetwork: true. VMs remain billable until explicitly deleted and currently use a fixed profile of 0.5 CPU, 1 GiB memory, and a minimal Ubuntu image. The beta does not include inbound ports, SSH, custom images, or volumes.
Why client SDK generation belongs in the open
Google describes partnering with Speakeasy to open-source the OpenAPI code-generation suite used for new SDKs for its Interactions, Agents, and Webhooks APIs. The change follows the May 2026 shutdown of a proprietary SDK-generation provider, which exposed platform risk while Google was preparing the Interactions API for general availability; migration prioritized avoiding breaking changes and preserving type definitions, strict error hierarchies, and streaming behavior. The AGPLv3 suite generates statically typed libraries for Python, TypeScript, Go, Java, C#, PHP, and Ruby, plus standalone agent-native CLI binaries and documentation MCP servers built from OpenAPI specifications and Markdown. Google says a deterministic generator paired with Antigravity AI agents now supports its pipeline across six targets, including three released SDKs, with roughly one engineer maintaining it, while generated code can remain under a chosen license such as MIT or Apache 2.0.
ClickHouse is now available on the dbt platform
The ClickHouse adapter for dbt v2, dbt’s Rust rewrite, entered public beta on September 16, 2026, while ClickHouse became a natively supported data warehouse on the dbt platform in private beta. The v2 adapter ships inside the open-source dbt binary, connects through an ADBC driver using Apache Arrow, and supports both open-source ClickHouse and ClickHouse Cloud. Existing models, tests, and profiles carry over, although some features remain incomplete and dbt plans to support the v1 and v2 adapters in parallel. The platform integration provides ClickHouse connections for Studio, environments, scheduled jobs, and Catalog, while the planned path to general availability includes parity items such as ON CLUSTER DDL and distributed materializations, followed by Fusion capabilities.
Rider and ReSharper 2026.2.2 Are Out!
Version 2026.2.2 of ReSharper, Rider, and .NET tools is available through the products, Toolbox App, or website. Rider adds an AI Agent Setup widget to the bottom-right status bar, where users can review supported MCP tools, skills, and hooks, see which are enabled, and open the relevant settings. Its hooks now give agents narrower inspection results for newly added code, while the Reformat file hook reports IDE formatting changes as a diff; dotCover also adds TUnit coverage, requiring JetBrains.dotCover.Framework and Microsoft.Testing.Platform 2.3.0 or later. The release fixes a macOS backend-resume freeze, removes dependence on Unity editor executable names for attachment, and enables MCP file operations across attached solution folders; ReSharper also receives TUnit coverage support.
Welcoming Roberto Braga, our new Growth Marketer
Resend welcomes Roberto Braga as its new Growth Marketer, adding a leader with more than 10 years of experience building and scaling technology businesses. He previously co-founded and served as CMO of YC-backed BX Blue, led growth through its acquisition by PicPay, ran organic growth at PicPay with SEO and ASO, and most recently was Reddit’s Country Growth Lead in Brazil. At Reddit, he helped double the platform’s DAU through content and partnership-led growth strategies; at Resend, he plans to create the Growth discipline and systematize the factors driving user acquisition and retention. Braga describes experimentation, channel mixing, email, and user conversations as central to his work, and advises growth marketers to focus on user pains rather than the newest tools or frameworks.
What's new in ClickStack - Aug ’26
The August ClickStack update covers five releases, v2.34 through v2.38, with dashboards as the main focus. Dashboard variables are generally available, letting filters supply selected values to raw SQL, builder fields, Lucene, and PromQL queries, while chained filters can narrow one another. Charts add formulas for combining series, a metrics explorer previews emitted metrics, and release markers align service versions with events such as latency spikes. The update also introduces the TimeSeries engine and PromQL support in private preview for Managed ClickStack and experimentally in open source, alongside a beta LLM observability dashboard, alerting improvements, OIDC collector authentication, and MCP server changes, including up to ten notification targets, alert names and tags, evaluation history through the API, and richer webhook payloads.
Vibe Production-Ready Apps with Auth0 and v0
Auth0 is launching an integration for v0 that lets builders add real authentication to prompt-built applications. v0 can respond to requests for login, protected routes, B2B use cases, enterprise identity providers, or MFA by creating Auth0 resources, configuring connections, and wiring its SDK into generated code. The integration operates within the v0 conversational workflow and builds on Auth0’s native Vercel integration, which syncs tenant configuration and credentials across development, preview, and production environments. This replaces placeholder authentication screens with authenticated sessions, protected access, and Auth0-specific implementation patterns including real session handling and protected routes. It is available in any v0 project today, with setup beginning by installing Auth0 from the project’s Integrations settings.
Agent Anomaly Detection, now in Private Preview on the Gemini Enterprise Agent Platform
Agent Anomaly Detection is a reasoning-based oversight and audit layer for autonomous agents on the Gemini Enterprise Agent Platform, now in Private Preview. It analyzes existing reasoning traces, tool calls, execution flow, logs, and OpenTelemetry traces asynchronously, using a lightweight statistical pass followed by deeper LLM-based examination of flagged sessions. Its initial detectors cover tool misuse, identity and privilege abuse, cascading failures, rogue agents, resource exhaustion, and token usage escalation, with findings assigned severity, probability, explanations, and recommended fixes and surfaced in Security Command Center. In the Inventory Agent example, repeated large-batch, offset-jumping list_inventory calls are classified as systematic scraping and produce a Critical resource-exhaustion finding at 95% probability; an API can let ADK callbacks or plugins block later actions. Custom business logic detectors are described as coming soon.
From better privacy to our new ChatGPT plugin, here's what's new on Stack Overflow for Agents
Stack Overflow for Agents is an API-first knowledge exchange designed to address the “ephemeral intelligence gap,” in which agents lose solutions when a session’s context window disappears. The platform preserves agent-generated knowledge and adds trust scores, validation gateways, reputation-linked posts, and steering context to encourage verification and corrections. After three months, Stack Overflow has introduced a ChatGPT plugin that packages its existing skills into one installable OpenAI capability, plus Playbooks for structured procedural workflows distinct from Blueprints and TILs. New controls let users choose whether agents post locally, save drafts, request review before publishing, or post autonomously; read-only access supports proprietary work. The team says agents are already using and improving shared knowledge, but it is still seeking conclusive, quantifiable evidence of the platform’s value.
Replica-aware routing public beta
ClickHouse’s replica-aware routing is now in Public Beta for Enterprise customers, addressing cases where temporary tables and named sessions become invisible after a request reaches another replica. The feature routes requests to a consistent replica using an X-ClickHouse-Replica-Tag or a native TLS SNI override, supporting session-scoped access and read-after-write consistency. Over HTTP, Envoy reads the header and uses consistent hashing; native connections decouple the SNI used for routing from the hostname validated against the certificate. Stickiness is best-effort and can change after upgrades, restarts, or scaling, so temporary objects and session settings may need recreation. The feature is available through service settings for Enterprise plans on standard ClickHouse Cloud and BYOC.
Introducing ClickHouse's new TimeSeries Engine: Your drop-In Prometheus replacement
ClickHouse announces the private preview of PromQL and its TimeSeries table engine in ClickHouse Cloud, allowing Prometheus metrics to be sent through remote write and queried in ClickStack, Grafana, or ClickHouse. Prometheus metrics are shaped by pull-based collection: applications expose current state, collectors add scrape-time timestamps, and types such as counters, gauges, histograms, and summaries determine interpretation. PromQL preserves the resulting semantics, including counter reset handling, range-window extrapolation, and histogram bucket processing, rather than requiring teams to reproduce those rules in SQL or a translation layer. The announcement describes limited preview access, says supported functions and operators are documented separately, and identifies future work around downsampling, native histograms, rules, additional protocols, and direct OpenTelemetry export.
Have it both ways: stay discoverable in search while disallowing AI training
Cloudflare announces a Disallow AI Training setting intended to let website owners refuse AI training while keeping content available to search crawlers. The problem is mixed-use crawlers such as Applebot, Bingbot, and Googlebot, which can serve both search indexing and model training, making a simple block affect discoverability. Cloudflare says its network can publish preferences, identify and classify crawlers, block those that ignore controls, and report operator behavior on Radar; the setting publishes a no-training preference through robots.txt while allowing Accountable mixed-use crawlers for search. Apple, Google, and Microsoft meet or have committed to meet the Accountable requirements, which include training and summary opt-outs, URL-level visibility, metrics, and assurance that training opt-outs will not affect traditional search.
Give every teammate and agent the right level of access to your Workers
Cloudflare has introduced resource-level access controls for Workers, allowing a teammate or agent to access one specific Worker rather than other resources in an account. Four roles define progressively broader capabilities: Metadata Read-Only exposes settings and observability data, Content Read-Only permits code or product-content reads, Editor allows content and settings changes without resource deletion, and Admin provides full control. These roles can be assigned to dashboard users or attached to scoped API tokens, supporting debugging without source exposure, code review without deployment, and CI/CD deployments limited to one Worker. Worker-level access also governs Durable Objects, while routes and Custom Domains require both Worker Editor access and Workers Routes permission; existing legacy permissions continue to work, but the new roles are recommended for granular access and are planned for D1, R2, and KV.
Let’s talk wait times and delays
The update explains how drivers can be compensated when pickups, additional stops, route changes, or road delays make a trip take longer than expected. At the first pickup, wait-time and no-show fees may apply, with the pickup screen showing elapsed wait time and potentially applicable amounts; at an additional stop, stop-time fees now begin after one minute rather than two, and the app displays both waiting time and earnings. If a rider adds a stop or changes the destination, the app shows the new drop-off address and fare change. For eligible trips running at least five minutes longer than estimated from pickup to drop-off, Delayed Ride Guarantee can automatically increase the fare, with higher potential earnings for trips exceeding 15 extra minutes; receipts explain the adjustment, reason, and amount, while eligibility varies by location and trip type.
Announcing On-Demand State Repartitioning for Apache Spark™ Structured Streaming on Databricks
Stateful Apache Spark Structured Streaming queries historically locked their state-store partition count into the checkpoint, so changing spark.sql.shuffle.partitions after a workload grew had no effect without rebuilding and losing accumulated state. Databricks Runtime 18 and later introduces on-demand state repartitioning, a Public Preview feature that preserves the checkpoint while moving state to a new partition layout. Operators set spark.sql.streaming.stateStore.partitions, stop the query, and restart it; the query finishes any pending microbatch, physically rehashes and redistributes state, then resumes with the requested count. The feature applies to aggregations, stream-stream joins, deduplication, sessionization, and transformWithState, provided the RocksDB state store is used. Repartitioning pauses processing and its duration is reported in controlBatch.REPARTITION; Coveo reports a 40% reduction in related Amazon S3 API costs.
Toolbox App 3.8: Improves IDE Update Handling on macOS and Fixes Keyboard Navigation
Toolbox App 3.8 addresses IDE update handling on macOS and restores keyboard navigation in project and tool lists. On macOS, manual IDE updates remain available when the system incorrectly reports an installation directory as non-writable, with instructions shown if macOS blocks the update. On Windows, Ctrl+1 and Ctrl+2 switch between the Tools and Projects tabs, while the Up Arrow, Down Arrow, Page Up, Page Down, Home, and End keys navigate lists, including filtered results. Cleanup of leftover IDE directories now displays progress for each tool and the full operation, and disables delete controls until cleanup and rescanning finish, preventing duplicate cleanup starts.
Python 3.14 free-threaded build is now available in RHEL
Red Hat Enterprise Linux 9.8 and 10.2 now provide a free-threaded Python 3.14 build alongside the regular interpreter, enabling developers to test parallel CPU execution with threads. The build disables the GIL, allowing Python threads to execute on multiple CPU cores in one process, while built-in dict, list, and set operations retain internal locking for individual operations. Developers install the python3.14-freethreading package from the CodeReady Linux Builder repository; it provides the separate python3.14t executable and commands to verify free-threading support and GIL status. Existing code may expose race conditions, and unsupported C-extension dependencies can re-enable the GIL, so the source recommends testing, dependency checks, explicit synchronization, and workload measurement. The build carries a stated 5%-10% single-threaded performance overhead and mainly targets CPU-bound threaded workloads.
Product updates: Sandbox Sidecars, new models, a refreshed dashboard, and more
Modal added day-zero support for Kimi K3, Qwen 3.8, GLM 5.3, and GLM 5.3 Flash on Auto Endpoints, with custom DFlash speculators boosting throughput to 460 tokens per second. New environment-level budgets give Team and Enterprise workspaces per-environment compute limits, while the pricing multiplier for broad region selection dropped from 1.5x to 1.15x. The dashboard got a refreshed navigation, color system, and beta light mode, and Private Environments now support a default No Access role. Sandbox Sidecars are in public alpha, running additional containers via low-latency internal networking, and VM Sandboxes are in public beta with a real Linux kernel for Docker and eBPF. Sandbox directory snapshots and a new filesystem API are now GA, and regional Proxies allow selecting a region for static outbound IPs, while SDK updates improved log APIs and autoscaler reporting.
