@​astrojs/rss@​4.0.19

Patch Changes

• #17209 fbcfa03 Thanks @​matthewp! - Hardens RSS feed generation by escaping the source and enclosure item fields. These fields are now serialized as structured XML values, ensuring that special characters in values like source.title and enclosure.type are always treated as text rather than markup, consistent with how other feed fields are handled.

Updates @microsoft/applicationinsights-web from 3.4.1 to 3.4.3

Changelog

Sourced from @​microsoft/applicationinsights-web's changelog.

3.4.3 (July 2nd, 2026)

This is a maintenance release for the 3.4.x version line adding a new SDK statistics feature, a PostChannel reliability fix, and dependency security hardening. The @microsoft/1ds-post-js channel is numbered 4.4.3 and requires v3.4.3.

Significant Changes (since 3.4.2)

• Customer SDK Stats: Added a new SdkStats feature that periodically collects internal SDK usage/health statistics. It is enabled by default and can be disabled (or explicitly configured) via the featureOptIn configuration (e.g. featureOptIn: { SdkStats: { mode: FeatureOptInMode.disable } }); the collection interval defaults to 15 minutes (sdkStats.int).

• PostChannel Auto-Flush Stall Fix: Fixed a permanent stall in @microsoft/1ds-post-js where, under sustained intermittent send failures (e.g. a load balancer returning occasional 503s), auto flush could wedge behind the flush() wait-for-idle timer and permanently stop draining the in-memory queue — causing telemetry to be silently dropped as QueueFull until the process was restarted. Auto flush is now fire-and-forget and no longer parks the scheduler waiting for the manager to become completely idle.

• Dependency Security Hardening: Pinned tar to >=7.5.16 to remediate CVE-2026-53655 and resolved the remaining npm audit findings in build tooling via dependency overrides (js-yaml, yaml, markdown-it, linkify-it). These are build/tooling changes and do not affect the published runtime packages.

Changelog

• #2746 Fix PostChannel auto-flush permanent stall under sustained intermittent send failures
• #2745 fix(security): pin tar >=7.5.16 to remediate CVE-2026-53655
• #2707 Enable Customer SDK Stats
• Resolve remaining npm audit findings via dependency overrides (js-yaml, yaml, markdown-it, linkify-it)

Full Changelog: microsoft/ApplicationInsights-JS@3.4.2...3.4.3

3.4.2 (June 18th, 2026)

This is a maintenance release for the 3.4.x version line containing security hardening, bug fixes, build tooling improvements, and CI updates. The @microsoft/1ds-post-js channel is numbered 4.4.2 and requires v3.4.2.

Updates astro from 6.4.6 to 7.1.1

Release notes

Sourced from astro's releases.

astro@7.1.1

Patch Changes

• #17399 4b03702 Thanks @​matthewp! - Fixes encoded request paths being routed incorrectly when using domain-based i18n

astro@7.1.0

Minor Changes

• #17302 5f4dc03 Thanks @​astrobot-houston! - Adds a new deferRender option to the glob() content loader

  When set to true, renderable entries (such as Markdown) are not rendered during content sync. Instead, rendering is deferred until the entry is actually rendered in a page, using the same on-demand path that .mdx files already use.

  This reduces memory usage during astro build for large collections whose rendered output is much larger than the source — for example, Markdown that uses heavy rehype plugins like rehype-katex. Such builds could previously run out of memory while storing the eagerly-rendered HTML for every entry.

  // src/content.config.ts
  import { defineCollection } from 'astro:content';
  import { glob } from 'astro/loaders';
  const docs = defineCollection({
  loader: glob({ pattern: '**/*.md', base: 'src/content/docs', deferRender: true }),
  });

  By default deferRender is false, preserving the existing behavior of rendering entries eagerly during sync so their rendered HTML can be cached across builds.

• #17296 30698a2 Thanks @​ematipico! - Adds a new experimental collectionStorage option for controlling how the content layer persists its data store

  By default, Astro serializes the entire content layer data store to a single file (.astro/data-store.json). For very large content collections, this file can grow large enough to hit platform file-size limits.

  Set experimental.collectionStorage: 'chunked' to instead split the data store across many smaller, content-addressed files inside a .astro/data-store/ directory, described by a manifest:

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  export default defineConfig({
  experimental: {
  collectionStorage: 'chunked',
  },
  });

  Because each part file is named by a hash of its contents, unchanged parts keep the same name across builds and are not rewritten, and identical parts are deduplicated. The default value is 'single-file', which preserves the current behavior.

• #17214 44c4989 Thanks @​ematipico! - Adds support for the more specific CSP directives script-src-elem, script-src-attr, style-src-elem, and style-src-attr through a new kind option.

  Previously, CSP was only scoped to generic script-src/style-src directives. Now each source or hash can be scoped to a narrower directive — for example, to allow inline style attributes (such as those from define:vars or Shiki) without loosening the policy for your <style> and <link> elements.

Updates @playwright/test from 1.60.0 to 1.61.1

Release notes

Sourced from @​playwright/test's releases.

v1.61.1

Bug Fixes

• #41365 [Bug]: Expect.Extend matcher with same name as default matcher in same expect instance overrides default matchers implementation to custom matcher
• #41351 [Bug]: Playwright UI mode: apiRequestContext._wrapApiCall reports unexpected number of bytes (same test passes in headed mode)

• #41311 [Bug]: [Regression]: Sync loader throws "context.conditions?.includes is not a function" on Node 22.15
• #41371 [Regression]: Sync ESM loader (registerHooks) fails to resolve extensionless .ts subpath imports across pnpm workspace symlinks

v1.61.0

🔑 WebAuthn passkeys

New Credentials virtual authenticator, available via browserContext.credentials, lets tests register passkeys and answer navigator.credentials.create() / navigator.credentials.get() ceremonies in the page — no real hardware key required, works in all browsers:

const context = await browser.newContext();
// Seed a passkey your backend provisioned for a test user.
await context.credentials.create('example.com', {
id: credentialId,
userHandle,
privateKey,
publicKey,
});
await context.credentials.install();
const page = await context.newPage();
await page.goto('https://example.com/login');
// The page's navigator.credentials.get() is answered with the seeded passkey.

You can also let the app register a passkey once in a setup test, read it back with credentials.get(), and seed it into later tests — see Credentials for details.

🗃️ Web Storage

New WebStorage API, available via page.localStorage and page.sessionStorage, reads and writes the page's storage for the current origin:

await page.localStorage.setItem('token', 'abc');
const token = await page.localStorage.getItem('token');
const items = await page.sessionStorage.items();

New APIs

Network

• apiResponse.securityDetails() and apiResponse.serverAddr() mirror the browser-side response.securityDetails() and response.serverAddr().

Fixed

• Support --watch --poll[=ms] in @tailwindcss/cli when filesystem events are unreliable or unavailable (#20297)
