## DialNexa changelog for August 2026

## 10th August, 2026

### [MCP OAuth and batch preparation tools](/docs/mcp-tools/overview#dialnexa-mcp-server-endpoint-and-authentication)

Added [OAuth 2.1 sign-in and consent guidance](/docs/mcp-tools/quickstart#step-2-sign-in-and-review-consent) for MCP-compatible clients while retaining workspace API key authentication. Expanded the Batch Calls MCP reference with read-only [`clean_batch_call_names`](/docs/mcp-tools/batch-calls/clean-batch-call-names) and [`preview_batch_call_leads`](/docs/mcp-tools/batch-calls/preview-batch-call-leads) tools for reviewing small lead files before creating a campaign.

### [Agent Builder workspace assistant controls](/docs/agents/ai-agent-builder#workspace-questions-and-approved-actions)

Updated [Agent Builder](/docs/agents/ai-agent-builder#workspace-questions-and-approved-actions) for workspace questions, action approval cards, message editing and retry, response feedback, prompt warnings, and visible assistant session history. These controls help users review assistant proposals before a workspace change runs.

### [Batch campaign progress rollups](/docs/batch-calls/retries-and-statuses#campaign-counters-and-attempts)

Updated [Batch Call Retries And Statuses](/docs/batch-calls/retries-and-statuses#campaign-counters-and-attempts), [Statuses](/docs/reference/statuses#batch-call-statuses), and [List Batches](/docs/api-reference/v1/batches/list#response-counters) for `picked_up_calls`, `last_call_sent_at`, and the legacy `picked_up_lead_count` compatibility field.

### [Fallback STT validation and billing guidance](/docs/voice-ai/speech-to-text-and-transcription#fallback-stt)

Updated [Speech To Text And Transcription](/docs/voice-ai/speech-to-text-and-transcription#fallback-stt), [Languages Voices Models And Transcribers](/docs/agents/languages-voices-models-and-transcribers#fallback-stt), and the agent API reference to explain the different-provider requirement, current selector pricing, transaction checks, and duplicate fallback-result protection.

### [Voice runtime recovery and continuity](/docs/voice-ai/llms-and-conversation-behavior#empty-model-response-recovery)

Updated [LLMs And Conversation Behavior](/docs/voice-ai/llms-and-conversation-behavior#empty-model-response-recovery), [Text To Speech And Voices](/docs/voice-ai/text-to-speech-and-voices#streaming-speech-continuity), and [Web Calls](/docs/calls/web-calls#creation-and-warmup-behavior) for one retry after an empty model response, language-aware filler during slow turns, word-boundary speech continuity, and call-scoped web teardown.

## 3rd August, 2026

### [MCP reference redesigned for developers](/docs/mcp-tools/quickstart#verify-tool-discovery)

Reorganized the [MCP Tools reference](/docs/mcp-tools/overview#dialnexa-mcp-tool-reference) into one source-backed page per tool. Added resource overviews, safety labels, required-input request shapes, verification and retry guidance, a [quickstart](/docs/mcp-tools/quickstart), [response and error handling](/docs/mcp-tools/errors), and redirects from the previous collection pages.

### [API key rotation and v1 deprecation errors](/docs/api-access/key-rotation#dialnexa-api-key-rotation-choices)

Updated [API Keys](/docs/api-access/api-keys#api-key-actions), [Key Rotation](/docs/api-access/key-rotation#dialnexa-api-key-rotation-choices), [API Introduction](/docs/api-reference/introduction), [Migrating To V1](/docs/api-reference/v1/migrating-to-v1), and [Errors](/docs/api-reference/errors#common-http-status-codes) for Regenerate Key, expiry timestamps, the two-key limit, and legacy `410 Gone` responses.

### [Batch attempts and recipient review](/docs/batch-calls/retries-and-statuses#campaign-counters-and-attempts)

Updated [Batch Call Retries And Statuses](/docs/batch-calls/retries-and-statuses#campaign-counters-and-attempts), [Recipient Files](/docs/batch-calls/recipient-files#review-invalid-phone-numbers), [Recipient Results](/docs/batch-calls/recipient-results#what-recipient-results-show), [Statuses](/docs/reference/statuses#batch-call-statuses), and [Create Batch Call](/docs/api-reference/v1/batches/create#file-requirements) for attempt-stage counters, paused retry handling, phone-number review, screenshots, and the `35` character title limit.

### [Speech controls and voice AI cache behavior](/docs/agent-settings/speech-settings#interruption-sensitivity)

Updated [Speech Settings](/docs/agent-settings/speech-settings#interruption-sensitivity), [LLMs And Conversation Behavior](/docs/voice-ai/llms-and-conversation-behavior#prompt-caching), [Latency Turn Taking And Interruptions](/docs/voice-ai/latency-turn-taking-and-interruptions#healthy-cache-misses), [Provider Selection Guide](/docs/voice-ai/provider-selection-guide#fast-fallback-stack), [Text To Speech And Voices](/docs/voice-ai/text-to-speech-and-voices), and [Supported Voices And Models](/docs/reference/supported-voices-and-models#provider-comparison) for Interruption Sensitivity, fallback LLM defaults, prompt-cache skip rules, predictive cache misses, and the Cartesia Sonic 3.5 default.

### [Agent editor AI modifier suggestions](/docs/agents/ai-agent-builder#editing-an-existing-agent-with-ai)

Updated [Agent Builder](/docs/agents/ai-agent-builder#editing-an-existing-agent-with-ai) with the in-editor AI modifier screenshot, diagnostic answers, suggested chips from recent call evidence, and activity-feed behavior during AI edits.

### [Billing low balance alerts](/docs/platform/billing-and-wallet#current-billing-wallet-behavior)

Updated [Billing And Wallet](/docs/platform/billing-and-wallet#current-billing-wallet-behavior) with the refreshed Recharge tab screenshot, low balance alert wording, early warning email behavior, and transaction-history guidance for pre-campaign checks.
