v1.1.1

Added

• request.fetch and request.fetchOptions options (on the TelegramBot
  constructor / HttpClient), for per-instance transport customization. Pass a
  custom fetch implementation (e.g. undici's fetch bound to a ProxyAgent),
  or extra fetch init such as an undici dispatcher, scoped to a single bot
  instance - no setGlobalDispatcher, so other clients in the process are
  unaffected. This restores the per-instance proxy capability that the legacy
  request.agent provided before the move to the built-in fetch. (#1319)

  import TelegramBot from "node-telegram-bot-api";
  import { ProxyAgent } from "undici";
  
  const bot = new TelegramBot(token, {
    polling: true,
    request: { fetchOptions: { dispatcher: new ProxyAgent("http://127.0.0.1:8080") } },
  });

Fixed

• editMessageMedia now accepts a Buffer / stream / local file path for the new
  media (and its thumbnail / cover), uploading it via an attach:// part -
  previously only a file_id / URL or the legacy attach://<local-path> form
  worked. Resolved through the same _buildMediaItems pipeline as
  sendMediaGroup; string callers and the old attach://<local-path> form are
  unaffected.
  (#1189)

• Breaking: createNewStickerSet and addStickerToSet were still sending the
  long-removed png_sticker / emojis fields, which Telegram rejects with
  400 Bad Request: invalid sticker emojis. They now use the current Bot API
  shape - a single options object carrying stickers: InputSticker[] (or a single
  sticker: InputSticker), where each sticker's file (Buffer / stream / local
  path) is uploaded via an attach:// part, while a file_id / URL string passes
  through unchanged.

  // Before (broken):
  bot.createNewStickerSet(userId, name, title, pngSticker, "😀");
  
  // After:
  bot.createNewStickerSet({
    user_id: userId,
    name,
    title,
    stickers: [{ sticker: "./a.png", format: "static", emoji_list: ["😀"] }],
  });
  bot.addStickerToSet({
    user_id: userId,
    name,
    sticker: { sticker: "./b.webp", format: "static", emoji_list: ["🎈"] },
  });
