Feature Changes

BitTorrent:

• rewrite piece scheduling with a strict endgame that never asks one peer for the same block twice
• ban peers whose blocks keep failing hash checks (bt-ban-corrupt-peers, bt-ban-corrupt-strikes)
• answer Cancel with Reject (BEP 6), advertise reqq and upload_only, keep tracker tier failover
• add a live session-wide connection budget (bt-max-connections, default 400) with a reserve for magnet metadata fetches, and treat descriptor exhaustion as back-pressure
• serve uploads from a bounded read cache of 128 KiB windows instead of one read per block
• adapt upload slots between 4 and 12 like libtorrent's rate-based choker, with a separate optimistic slot and smoothed rates
• leave UPnP mappings of other LAN hosts alone, rename files whose sanitized paths collide, stop torrents gracefully on shutdown and rebuild SOCKS5 UDP associations

Engines and app:

• share one rate limiter across HTTP, BT, ed2k and Usenet and apply limit changes live
• wake idle HTTP workers on demand instead of polling every 100 ms
• pipeline NNTP article requests and fetch PAR2 recovery volumes only when repair needs them
• resume ed2k downloads from a .part file with an MD4-verified sidecar, support files over 4 GiB with large-file capable peers, re-ask queued sources and run Kad as a sliding-window lookup
• give each HLS task its own temp folder and add the giFT toggle and connection settings
• generate an RPC secret on first run and reject browser-origin and state-changing GET calls
• create the tray panel and clipboard prompt windows on first use and virtualize long lists
• fix the Android Gradle script and gate desktop-only helpers out of Android builds

Release and CI:

• All release progress can be driven by creating release in github now
• publish npm packages only after every app build of the release succeeded
• drop packages/* from the pnpm workspace so the lockfile no longer pins unpublished packages
• build only macOS x64, Windows x64 and Android arm64 for manual runs
• install only platform-tools in setup-android

Breaking Changes

• The RPC server now requires a secret, one is generated on first run. Browser-origin requests and state-changing GET calls are rejected while no secret is set.
• BitTorrent binds listen-port 21301 by default instead of an ephemeral port.
• a DoH NXDOMAIN or NODATA answer no longer falls back to system DNS.
• re-adding a torrent whose info hash belongs to a stopped task is refused.
• Firefox and Safari host-only cookies now match the exact host only.
• ed2k downloads use <name>.part with a <name>.part.met sidecar.
• the engine no longer defaults allow-overwrite, continue, follow-torrent, bt-enable-lpd, bt-exclude-tracker, enable-dht, enable-dht6 or enable-peer-exchange. Saved values are still accepted but have no effect.
• risuko-bt removes SessionOptions.list_only and ListOnlyResponse.
