4.91v

1. Notable changes since 4.90v
   - Chat widget CAPTCHA providers: added Google reCAPTCHA v3 and Cloudflare Turnstile support for verifying chat widget visitors through provider-based CAPTCHA validation; CAPTCHA settings gained a chat-specific enable flag and a configurable reCAPTCHA v3 score threshold; a dedicated widget CAPTCHA helper loads the provider script and resolves the token, which is now sent and verified as part of the widget online chat submission; the CAPTCHA settings screen gained a provider toggle and CAPTCHA settings are exposed through the widget online settings endpoint.
   - Canned message replaceable variables: added a `configuration` field to `lh_canned_msg_replace` storing per-variable JSON options to hide the variable value from the replaceable variables list ("Hide value in list") and to restrict management of the variable to operators holding the new `use_replace_sensitive` permission of the `lhcannedmsg` module ("Restricted access"); restricted variables show a "Restricted" badge, their value and clone/edit/delete actions are hidden from operators without the permission, and access control is enforced in the clone, edit and delete handlers.
   - Exact counts for chat and mail searches: the chat and mail conversation search panels gained an "Exact count" toggle; by default the result total is capped by counting only the first 1,000 matching rows through new `limit_count` support in `getCount()`, avoiding slow full-table scans on large result sets, and the paginator shows an approximate total ("~") whenever the count was capped; enabling "Exact count" performs a precise count of every matching row.
   - Bot REST API actions: authentication credentials used for NTLM, Bearer token and API key (header and query parameter) requests now resolve through replaceable variables; authorization headers are masked in debug logs by shortening them from both sides so secrets are not exposed; new user language dynamic variables (`{{user_locale}}`, `{{user_site_access}}`, `{{user_content_language}}`, `{{user_content_language_name}}`) were added for REST API bot actions, backed by a new `user_language` magic property on the chat model; streaming requests gained a configurable row start pattern so response streams that do not use the SSE `data: {` prefix are parsed correctly.
   - Bot trigger arguments: invisible message arguments (`{message_invisible_N}`) passed from the widget are now consistently forwarded to every trigger execution path, including theme-based bot trigger execution and the default trigger, by centralizing trigger argument processing early in the widget online submission flow.
   - Offline reasons for operators: the offline reasons feature now supports operator access control through a new `offlinereasons_operator` permission that can be granted with limitations restricting operators to specific reasons; the status (online/offline) modal shows a reason selector when an operator goes offline and stores the selection as `offline_reason_id`, and only the reasons an operator is allowed to use are exposed in the dashboard and status modal; the permission editor and "who grants" summary show the offline-reason limitation, specific function limitations are now respected over wildcard grants, and offline reasons can be deleted.
   - Statistics averages: agent statistics averages now include the full result set instead of trimming the highest and lowest ten percent, and preserve fractional values when computing the averages.
   - Security hardening: file downloads in incoming webhooks and online-user avatar fetching were hardened against SSRF - only HTTP/HTTPS URLs are accepted, `localhost` and private/reserved IP addresses are rejected, the resolved hostname is pinned to a validated IP to prevent DNS rebinding, and redirect following is disabled; message validation and the message preview modal were fixed.
   - Reliability: the bot "Close chat" command now runs inside a database transaction with row locking to prevent race conditions and partial state updates during chat closure; the mail conversation fetch API returns an error instead of failing fatally when the conversation cannot be found; mailbox syncing now limits SQL statement execution and lock-wait time and sets IMAP open/read/write/close timeouts so a slow mail server cannot stall the sync process.
   - Message masking test tool: added a chat-context simulation mode where a chat and a test message are supplied and the tool reproduces the real widget masking flow with step-by-step diagnostics (chat found, guardrails enabled, chat assigned to operator, matching masking rule, operator permission, masking result) using the chat's department, assigned operator and permissions, along with clearer explanations.
   - Miscellaneous: added RAR and other MIME type detection for downloaded webhook attachments; added Latvian (`lv_LV`) and Estonian (`et_EE`) translations and updated the translation update script; widened the widget theme custom CSS fields from `text` to `mediumtext` to prevent CSS truncation; updated install scripts and database structure definitions; bumped version to 4.91v.

2. Summary
   - This release focuses on safeguarding sensitive data, richer chat widget CAPTCHA options, and performance tuning for large searches.
   - Chat widget visitors can now be verified with Google reCAPTCHA v3 or Cloudflare Turnstile, controlled by a chat-specific CAPTCHA switch and a configurable score threshold.
   - Canned message replaceable variables can hide their values from lists and be locked down to operators with a dedicated permission.
   - Chat and mail searches gain an "Exact count" option while default counts are capped and marked approximate for large result sets.
   - Bot REST API actions support variable-based authentication with masked secrets, user language variables, and flexible streaming row parsing, and invisible message arguments now reach all trigger workflows.
   - Offline reasons become permission-controlled, file downloads are hardened against SSRF, and mail fetching, chat closing, statistics averaging and translation coverage were improved.

4.89v

1. Notable changes since 4.88v
   - Online operators widget customization: added a new "Online operators widget settings" screen under Statistics (`statistic/onlineopsettings`) with a new `onlineop_settings` permission, letting operators choose which columns appear in the online operators dashboard widget (Name, Status, Last assignment, Live chats/free slots, Department, Reason for offline, Session duration) and their position; the widget now renders the configured columns, shows "offline since" in the name column when a dedicated column is hidden, restores expand/collapse actions, preserves passed column widths and allows controlling widget columns from the embed code.
   - Track who set a user offline: added `updated_by_user_id` column to `lh_users_online_session` recording which operator set a user offline or online; online-hours statistics gained a "Set offline by" column showing that operator, with the offline action attributed only to the operator who explicitly set the user offline; last visit is now updated when toggling the hide-online status in user edit.
   - Autoclose enhancements: all autoclose settings now accept fractional timeout values; the activity timeout supports sender-based modes by appending `,1` (close only when the visitor sent the last message) or `,2` (close only when the operator sent the last message) to the configured value; settings descriptions in the chat list configuration were clarified.
   - Chat cleanup on close: `cleanupOnClose()` is now executed when chats are closed via the cronjob or by changing their status (previously it only ran on manual close), removing orphaned records such as auto-responder chat links, bot repeat restrictions, bot chat events, pending bot events, voice/video sessions, transfers, group chats and temporary files; a new utility cron `cron/util/cleanup_orphan_chats_data` cleans orphaned chat data for chats that were closed before this fix, iterating chats from newest to oldest with an optional start chat id parameter.
   - Blocked users search: added a block type (`btype`) filter to the blocked users search covering all block types (IP, Nick, Nick and Department, IP + Nick, IP + Nick and Department, E-mail, Country, Online user, Sender E-mail).
   - Transfer department window: improved the transfer department window using the searchable multi-dropdown with radio selection and added `on_change` handler support to the multi-dropdown renderer.
   - Mail conversations: added "Expand all"/"Collapse all" actions to the mail conversation screen for quickly expanding or collapsing all message bodies.
   - Message edit history: added a new "Preview message" modal (`chat/previewmsg`) and an "Edited" link on edited admin messages opening the preview with the edit history.
   - Widget filters reset: "Reset widget filters" now clears widget local storage client-side instead of performing a server-side action; fixed a related typo.
   - Miscellaneous: added the Isle of Man flag icon; updated install scripts and database structure definition for the new column; bumped version to 4.89v.

2. Summary
   - This release focuses on dashboard customization and data hygiene.
   - The online operators widget becomes fully configurable with selectable and reorderable columns, backed by a new settings screen and permission.
   - Online-hours statistics now show which operator set a user offline, recorded in a new `updated_by_user_id` field.
   - Autoclose rules gain finer control with fractional timeouts and sender-based activity modes, while close-time cleanup is fixed for cron/status-driven closures, with a dedicated script to purge previously orphaned data.
   - Search, transfer, mail, and message-preview UX are improved across blocked users, department transfer, mail conversations, and edited-message history.

4.88v

1. Notable changes since 4.87v
   - Offline reasons: introduced configurable offline reasons with the new `lh_abstract_offline_reason` model and CRUD interface; operators can select a reason (e.g. "Lunch", "Meeting") with an icon when setting themselves offline, persisted on `lh_users` and `lh_users_online_session`; offline reasons are displayed in online-hours statistics and user-box menus with a redesigned status control layout; a new `offlinereasons` permission controls access to this feature.
   - Forms module overhaul: added comprehensive search and filtering for collected forms, including department filter, chat operator filter, date range, creator filter, and chat-time search; introduced field change tracking for internal forms — when an operator edits a previously submitted form, field history (old/new values and modifier) is logged; added translation support and improved template variable management for forms; refactored module navigation with proper permission checks and removed deprecated index page; enhanced embed code generation with access control; clearing chat attributes when deleting collected form data now properly reverts associated chat variables and additional data entries.
   - Bot enhancements: added secondary translations group support for bots, allowing an optional second translations group in bot configuration with proper validation and item retrieval from both groups; added "Trigger on bot skip" option to proactive invitations, executing triggers when a visitor skips the bot; fixed missing `last_msg_id` update after sending invitation messages.
   - Security hardening: refactored CAPTCHA to use browser fingerprinting (combining multiple HTTP headers) and SHA-256 hashing for improved security across chat validation, FAQ, voting, and widget modules; added more detailed CAPTCHA error messages; added `ignoreactivityglobal` permission allowing individual users to opt out of activity tracking; replaced redirect with proper permission-denied page for abstract list views; added `from_address` emptiness check to prevent mailbox sync failures on null sender addresses.
   - Performance and stability: improved MySQL reconnect logic by removing stale connection caching and properly resetting reconnect counters; guarded compiled config caching behind database connection checks to prevent warmup/CLI failures; wrapped `setinactive.php` in a transaction with row locking and added `syncAndLock()` to `setoffline.php` to prevent race conditions on online status updates; added `resetSession()` methods across persistent session helpers for clearing cached ezcPersistentSession instances; added server info panel showing address, name, port, software, and uptime in audit configuration.
   - Admin custom fields: refactored processing to prevent duplicate field values by moving admin fields after JS variable processing and tracking processed identifiers; admin custom fields with `uempty` show condition are now hidden from returning visitors who already have a non-default nickname set; added support for original author re-modifying fields.
   - UI and UX: updated Bootstrap badge classes from v4 to v5 (`badge-*` to `bg-*`) across GroupChat, operators template, and mailing import templates; improved assignment configuration UX; translated theme before survey rendering in `fill` and `fillwidget` modules; adjusted naming for less confusion; added server and user timestamps to audit config and login pages.
   - Miscellaneous: fixed #2400; added support for BOM UTF format files; added avatar caching; added search attribute support for extensions; fixed installer config validation with clearer error messages; refactored `addmsgadmin.php` input validation to handle missing input gracefully; handled edge database reconnect cases; fixed CAPTCHA time drift validation; ensured dynamic property support.

2. Summary
   - This release introduces a major new feature — configurable offline reasons — allowing operators to specify why they are offline with visual indicators across the UI and statistics.
   - The forms module receives a comprehensive upgrade with advanced search/filtering, field change tracking, translation support, and improved permission handling.
   - Bot capabilities expand with secondary translations groups and trigger-on-skip functionality.
   - Security is strengthened through CAPTCHA fingerprinting, SHA-256 hashing, and multiple permission/validation improvements.
