+# TypeType 1.5.1
 
-TypeType 1.5.0 adds private RSS feeds, new-upload notifications and better
-control over live content. It also closes a security issue in the public media
-proxy and improves SABR playback during resumes and long-distance seeks.
-
-## RSS And Notifications
-
-- Add private RSS feeds for all subscriptions or a selected set of channels.
-- Filter feeds by service and content type, with direct shortcuts from channel
-  pages.
-- Regenerate, disable or delete feed links without affecting subscriptions.
-- Show compact in-app notifications when subscribed channels publish new
-  videos. [#211](https://github.com/TypeType-Video/TypeType/issues/211)
-- Give instance administrators control over RSS availability, public base URL,
-  account limits, polling intervals and request rate limits.
-
-RSS access is private to each account. Feed tokens can be revoked at any time
-and do not expose the account session itself.
-
-## Subscriptions
-
-- Add account settings to hide live streams, upcoming streams or both from the
-  subscription feed. [#213](https://github.com/TypeType-Video/TypeType/issues/213)
-- Remove stale live entries after they stop being available from the provider.
-- Normalize channel tab URLs before fetching and caching subscription pages.
+TypeType 1.5.1 fixes YouTube captions and improves anonymous YouTube session
+startup.
 
 ## Playback
 
-- Restore saved playback positions reliably in Safari after SABR preparation.
-- Preserve the requested position while a SABR session is being prepared or
-  recovered.
-- Seek directly to distant positions before decoder preroll instead of replaying
-  unnecessary media.
-- Preserve play and pause intent through seeks and quality changes.
-- Update the web player to `@typetype/mse` 0.1.44.
+- Load YouTube caption tracks directly from the viewer's browser instead of
+  routing timed-text requests through the instance egress. This avoids
+  subtitle-only HTTP 429 responses caused by shared server IP addresses.
+- Preserve manual captions, automatically generated captions and translated
+  tracks. [#210](https://github.com/TypeType-Video/TypeType/issues/210)
+- Keep subtitle handling for NicoNico and BiliBili unchanged.
 
-## Security
+## YouTube Sessions
 
-- Restrict the public media proxy to supported provider hosts and approved
-  media paths.
-- Block private, loopback and local-network destinations, including redirect
-  and DNS resolution checks.
-- Keep cross-provider redirects outside the proxy allowlist.
-- Report YouTube remote-login readiness accurately instead of exposing an
-  unusable login flow.
-- Update application and build dependencies across the released services.
+- Bind the BotGuard challenge and event identifier to the same page-native
+  YouTube context and visitor session.
+- Use the current page context when generating anonymous YouTube tokens.
 
 ## Self-Hosting
 
-No manual database migration is required.
-
-RSS is disabled by default. Instance administrators can enable it and configure
-the public feed base URL from the documented environment settings.
-
-The account session lifetime and insecure-cookie development settings are now
-documented in English, French and Spanish.
-
-## Known Limitations
+No configuration or database migration is required.
 
-- YouTube may still throttle subtitle retrieval with HTTP 429 on some egress
-  addresses. [#210](https://github.com/TypeType-Video/TypeType/issues/210)
-- Native SABR playback on ARM64 remains under investigation.
-  [#204](https://github.com/TypeType-Video/TypeType/issues/204)
+Frontend, Server, Token and Downloader are aligned on version `1.5.1`.
