v1.6.3

## What's New

- Fluid-1 is 2.2x faster on Apple silicon. Existing users receive a one-time prompt to download and verify the new model, while keeping the previous model if they decline or the upgrade fails.
- FluidVoice can suggest Custom Dictionary replacements after you repeatedly correct dictated text.
- Train by Voice can save pronunciation samples for matching names and words that sound alike.
- Spoken punctuation formatting is now optional and configurable: choose the trigger phrase and edit its punctuation aliases in Custom Dictionary.
- Slash commands and @ phrases can be formatted while dictating, with the feature disabled by default.
- All Whisper models are back in the menu and it's faster than before!
- You can copy your most recent transcript from the menu bar, and click rows in Getting Started to open their relevant settings.
- AI dictation prompts can be configured to send only the dictated text instead of always adding FluidVoice's base prompt.

## Improvements

- Fluid-1 verifies backend-specific downloads before switching and keeps the previous backend until the replacement is ready.

## Fixes

- AI dictation now keeps each prompt's configured provider, fails closed when Fluid-1 is unavailable, preserves Local API processing with app-only routing, and clears retired Apple Intelligence settings without selecting a fallback.
- Voice-engine downloads now show continuous byte progress for Parakeet, Cohere, Nemotron, and Whisper models instead of appearing stuck at 0% or 3%.
- Custom Dictionary manual replacements can now use commas and other punctuation as the text FluidVoice should replace, and malformed duplicate entries no longer interrupt transcription.
- Train by Voice now preserves earlier pronunciation samples during retraining, includes them in app backups, and clears stale voice profiles after replacement edits or legacy backup restores.
- Custom Dictionary suggestions now respect Escape dismissals from any active app, and voice training continues correctly after an audio fallback.
- Custom punctuation aliases now drive symbol-context formatting consistently, including edited dictionary rules.
- Whisper readiness checks no longer create an empty model folder.
- Dictation AI enhancement now falls back to a standard response when a provider does not support streaming.
- Faster Recording Start now handles microphone layout changes correctly, avoids false fallbacks when audio processing is delayed, and uses the compatibility audio path if malformed audio is detected.
