v1.2.0 — Background Tab Scheduler

What's New

Scheduler — Background Tab Support

Scheduled messages now fire on time even when the tab is in the background.

Problem: Browsers aggressively throttle setInterval in hidden/background tabs — a 30-second timer could be delayed by a minute or more, causing scheduled sends to miss their window.

Fix: The scheduler tick is now driven by a Web Worker. Worker timers run on a separate thread and are not subject to the same throttling. The tab just needs to stay open — it does not need to be the active/focused tab.

• Falls back to plain setInterval in environments without Worker support
• All UI copy updated to clarify "tab open, not necessarily active"

v1.1.0 — Delete Message + RTL + Security Fixes

What's New in v1.1.0

New Features

Delete Message

WhatsApp-style delete confirmation modal — right-click any message or use the multi-select toolbar.

• Delete for everyone — unsends the message for all participants (only available for your own sent messages, within ~60 hours). Calls DELETE /message/delete/.
• Delete for me — removes the message from your local view only. Calls DELETE /message/deleteMessage/ (best-effort; always removes locally).
• Modal auto-dismisses when switching or closing conversations.
• Escape key closes the modal.
• Error toast shown if any message in a batch could not be deleted.

RTL / LTR Auto-Direction

Hebrew, Arabic, and other RTL text now renders correctly in every part of the UI. English stays left-to-right. No configuration needed — dir="auto" is applied per element, so mixed conversations work naturally.

Bug Fixes

Security

• XSS: avatar onerror no longer uses innerHTML with unescaped text
• XSS: quotedMsg.id sanitised before embedding in onclick attribute
• XSS: image lightbox uses data-src instead of raw URL in inline handler
• XSS: group name, subject, and description now escaped with chatEsc()

Crashes

• chatState.allFetchedMessages was uninitialised — fixed with [] default
• Location messages crashed on null m.text
• Location coordinates were not URL-encoded before being put into a Maps URL
• FileReader base64 split did not guard against a missing comma

API

• chatApiCall was silently dropping the request body on DELETE calls — Evolution API delete endpoints require a JSON body

Lifecycle

• Delete modal not dismissed on conversation switch → wrong JID could be used
• Delete modal not dismissed when closing a conversation
• chatCloseConversation did not reset select mode state
• Both confirm functions now guard against activeJid being null

UI / State

• Select toolbar delete button used a fragile attribute CSS selector; replaced with a stable id
• Delete button started enabled before first chatUpdateSelectCount call
• chatCopySelected / chatForwardSelected / chatDeleteSelected use Set.has() instead of Array.includes()

v1.0.1 — Fix scroll-up chat pagination

What's new in v1.0.1

Bug fixes

• Scroll-up now loads older messages — Chat history pagination was silently stopping after the first page. The app now correctly fetches additional pages from the Evolution API as you scroll up, with a loading spinner and preserved scroll position.

Technical details

• Rewrote chatFetchMessages to use the API's page-based response format ({ messages: { total, pages, currentPage, records[] } })
• Added chatFetchOlderFromApi() that fetches the next API page when local cache is exhausted
• historyFullyLoaded is now only set when the API confirms no more pages remain
• Cleaned up verbose debug console.log statements

v1.0.0 — WhatsApp Web Chat UI

What's New

WhatsApp Inbox (Chat Feature)

• Full WhatsApp-style inbox with real-time conversation list, message bubbles, and send/receive
• Contact name resolution: saved names, push names, and phone number fallback
• LID/phone JID deduplication — merges duplicate contacts (32+ duplicates eliminated)
• Group names fetched from authoritative group metadata API with in-memory verified cache
• Poll message rendering with vote aggregation, progress bars, voter avatars, and View votes detail panel
• Archive detection with triple API strategy and deep field scanning
• IndexedDB caching for conversations, contacts, and messages
• Search, filter (All/Unread/Favorites/Groups/Archived), pin indicators
• Media messages: send images, videos, documents, audio via drag-and-drop or file picker
• Reply-to-message support with quoted message preview

Send History

• Messages sent via Compose are now tracked in a Send History section under Scheduled Jobs
• Each entry shows recipients, message previews, success/fail counts
• Actions: expand details, resend (loads back to Compose), delete individual entries, clear all

Bug Fixes

• Group names: no longer show last sender name — uses dedicated verified cache from group metadata API
• Scheduled messages from Inbox: now saves correct phone number/group JID instead of internal database ID
• Recipient resolution: new chatResolveApiNumber() correctly handles groups, phones, LID, and DB internal IDs
• Poll votes: pollUpdateMessage no longer filtered as noise; vote aggregation tracks per-voter last-vote-wins
• Archive false positives: stopped marking all chats as archived when API filter returns same data as normal endpoint
• IndexedDB cache poisoning: v5 one-time cleanup wipes contaminated group names from previous bugs

UX Improvements

• Inbox is now the default tab on page load
• Compose message queue with Text, Media, Voice, Poll, and Buttons message types
