Makarski Bot Connector for Telegram

0.3.0

• New Broadcast feature: send messages to WordPress users with Telegram usernames from a dedicated admin page (Telegram Bot → Broadcast)
• Per-locale message composition — write separate texts for each language used by your users
• Message format selector: Plain text, HTML, or MarkdownV2
• Cron-batched delivery (200 messages/batch, ~20 msg/sec) — safe for large user bases without blocking the site
• Real-time progress bar with sent/failed counts and estimated time remaining
• Broadcast history table on the Broadcast page; per-user broadcast history on the user profile page
• New top-level “Telegram Bot” admin menu with Settings and Broadcast subpages
• New BotApi method: send_plain_message() — send a message without parse_mode
• Refactored broadcast admin code into TGBotAdminBroadcast class for consistency

0.2.43

• Auto-generate webhook secret on plugin activation so the mandatory secret check always has a value
• Fixed incoming message type detection: reuse already-parsed request object instead of re-calling get_request()

0.2.42

• Webhook secret is now required: all requests without a valid X-Telegram-Bot-Api-Secret-Token header are rejected
• Sanitize incoming text fields (message text, caption, callback data) before dispatching to action hooks
• Validate update_id presence after JSON decode
• Replaced direct curl in send_multipart_request() with wp_remote_post() + http_api_curl hook

0.2.41

• Renamed plugin folder and main file to match the approved WordPress.org slug makarski-bot-connector-for-telegram

0.2.40

• Webhook secret token support (X-Telegram-Bot-Api-Secret-Token header validation)
• Input sanitization improvements: absint() for chat_id, sanitize_textarea_field() for text in BotApi
• Core::set_current_user() hardened with get_userdata() check and absint()
• Added == External Services == section to readme.txt

0.2.30

• Renamed tgbot_process_multimedia_message to tgbot_message; added deprecated alias for backward compatibility
• Added tgbot_raw_message hook for advanced use cases
• Added media_group_id field to normalized message object

0.2.28

• Fixed PHP 8.5 deprecation: removed curl_close() (no-op since PHP 8.0)
• Fixed implicit nullable parameter in send_document()

0.2.27

• Added 11 new BotApi methods: send_chat_action, send_audio, send_voice, send_video, send_animation, forward_message, copy_message, send_location, delete_messages, set_my_commands, refund_star_payment

0.2.26

• Fixed callback_query commands (inline buttons) not dispatching in polling mode

0.2.25

• Auto-created user email now uses tg-{chat_id}@{site_domain} instead of {id}@example.com

0.2.22 – 0.2.24

• Fixed polling reschedule logic: moved to sanitize_callback so Save always applies mode even without settings change
• Removed debug logging from production code

0.2.18 – 0.2.21

• Fixed textdomain loading order (PHP notice in WP 6.7+)
• Fixed finish_request() header order for correct webhook response
