## What's New in v3.2.0
Version 3.2.0 simplifies the user experience significantly:
| Change | Before (v3.1) | After (v3.2.0) |
|--------|---------------|----------------|
| Credentials | 7 daily phrases | Single passphrase |
| Encode form | Date selection required | No date field |
| Decode form | Date detection/input | No date needed |
| Default words | 3 words | 4 words |
| Field label | "Day Phrase" | "Passphrase" |
**Key benefits:**
- ✅ No need to remember which day a message was encoded
- ✅ Simpler forms with fewer fields
- ✅ True asynchronous communication
- ✅ Stronger default security (4 words = ~44 bits entropy)
**Breaking Change:** v3.2.0 cannot decode images created with v3.1.x.

#### Automatic Mode Detection
The decoder automatically detects whether a stego image uses LSB or DCT mode. You don't need to specify the mode manually—it just works!
#### Date Detection from Filename
#### Decoding Process (v3.2.0 Simplified)
When you upload a stego image with a date in the filename (e.g., `stego_20251227.png`), the UI:
1. Extracts the date
2. Determines the day of week
3. Updates the phrase label: "Saturday's Phrase"
1. Upload the same reference photo
2. Upload the received stego image
3. Enter your passphrase (no date needed!)
4. Enter your PIN and/or RSA key
5. Click "Decode Message"
6. View decoded message or download decoded file

#### Troubleshooting Tips
If decryption fails:
1. **Check the date** - Use phrase for encoding day, not today
1. **Check passphrase** - Must be exact match (case-sensitive)
2. **Same reference photo** - Must be identical file
3. **Correct PIN/RSA** - Match what was used for encoding
4. **Image integrity** - Ensure no resizing/recompression
4. **Image integrity** - Ensure no resizing/recompression (LSB mode)

| **Output Formats** | PNG or JPEG |
| **Resilience** | ✅ Survives JPEG compression |
| **Best For** | Social media, messaging apps, web sharing |
> ⚠️ **Experimental Feature**: DCT mode is marked experimental and may have edge cases. Test with your specific workflow before relying on it for critical messages.
| **Resilience** | ✅ Better resistance to analysis |
| **Best For** | Stealth requirements, frequency domain hiding |
**When to use DCT:**
- Posting to social media (which recompresses images)
- Sharing via messaging apps (WhatsApp, Telegram, etc.)
- When channel may apply JPEG compression
- When stealth is important
- Smaller messages that fit in reduced capacity
- When you want JPEG output for natural appearance
#### DCT Output Formats
| Format | Pros | Cons |
