Granular key permissions, proactive alerts, and rich bot tables¶

A major Telegram bot update delivers deeper self-service capabilities: granular model access control per API key, a reliable asynchronous notification outbox, media attachments in support tickets, and interactive rich tables.

New capabilities¶

Granular per-key model permissions¶

Customize permitted models for each API key individually: grant full access, restrict the key to a specific model family (GPT / Codex, Claude), or select an exact subset of models.
Spend control: isolate experimental projects or third-party tools from costlier models.
Empty permission safeguards: the bot blocks saving any key configuration with zero enabled models.

Asynchronous notifications and balance tracking¶

Introduced a background notification outbox engine for reliable delivery.
Instant balance top-up notifications showing the credited amount and updated account balance.
Proactive low-balance threshold alerts with intelligent de-duplication to prevent repetitive notifications.

Support ticket attachments and media¶

Attach screenshots, logs, and document files when opening support requests or replying to operators.
Instant push notifications in Telegram when a support agent posts an update to an active ticket.

Rich model tables and custom history date ranges¶

Formatted rich tables in the Models section clearly displaying per-family pricing for input, output, and prompt caching.
Filter transaction history by custom date ranges, separated into top-ups, adjustments, and API debits.

Improvements¶

Unified button semantics and standardized back buttons ("« Back") across all bot screens.
Current page and filter state preservation in key lists when navigating to a key card and returning.
Sequential numbering and automated naming for newly generated keys.
Refreshed visual design for the bot logo and navigation icons.

Documentation¶

Substantially refreshed user documentation with quick start guides, client setup manuals, and complete bot walk-throughs.

Fixed issues¶

Models and keys¶

Long technical model identifiers no longer overflow or truncate in compact views.
Fixed pagination and filter reset bugs when editing key permissions.
Prevented blank card glitches when toggling model family selections.

Notifications and support¶

Eliminated duplicate low-balance warning alerts during bursts of small requests.
Fixed notification delivery glitches across support ticket status changes.

Existing API keys retain full access to all models until explicitly customized in the key management menu.
Open the Nexus Hub bot → Keys or Models to configure permissions and explore the updated tables.
Instructions are detailed in the Telegram bot guide.
