v0.26.0

Requires gotd/td v0.164.0 (https://github.com/gotd/td/releases/tag/v0.164.0). Release post: https://gotd.dev/blog/v0.164.0

Highlights

• Storage: persistent updates state and access hashes for pebble, bbolt and redis. pebble and bbolt also implement peers.Storage for telegram/peers.
• Fewer writes: pebble honours its write options and writes a whole update's peers in one batch instead of one fsync per peer. Unchanged peers aren't rewritten.
• Encoding: a compact binary peer encoding, opt-in with WithBinaryEncoding(). Versions before v0.26.0 can't read it, so turn it on only once you won't roll back.
• Min users no longer overwrite stored full users.
• floodwait: concurrent dispatch (a slow request no longer blocks the others), adaptive pacing, policies, exempt methods, retries of 5xx errors and a snapshot for metrics.
• Fixes: pebble skips only the peers it can't encode in a batch, bbolt iterates channels in a read-only transaction, floodwait uses its clock everywhere and decays the wait after errors.

Upgrading

• storage.Peer.FromUser returns false for min users.
• CreatedAt now means "first stored with this content".
• pebble writes without sync if you passed NoSync write options, which used to be ignored.
• floodwait runs requests concurrently; it used to send one per tick.
• bg still works, but gotd's Client.Start replaces it.
