# The Changelog

## 1.7
### The Andrew Release

**Features**

- Gravity Sync will now manage the `custom.list` file that contains the "Local DNS Records" function within the Pi-hole interface.
- If you do not want this feature enabled it can be bypassed by adding a `SKIP_CUSTOM='1'` to your .conf file. 
- Sync will be trigged during a pull operation if there are changes to either file.

**Known Issues**

- No new Star Trek references.

#### 1.7.1
- There is a changelog file now. I'm mentioning it in the changelog file. So meta.
- `./gravity-sync.sh version` will alert for new versions.

## 1.6
### The Restorative Release

**Features**

- New `./gravity-sync.sh restore` function will bring a previous version of the `gravity.db` back from the dead.
- Changes way that GS prompts for data input and how confirmation prompts are handled.
- Adds ability to override verification of push, restore or config reset, see `.example` file for details.
- Five new Star Trek references.

**Bug Fixes**
- New functions add consistency in status output.

## 1.5
### The Automated Release

**Features**

- You can now easily deploy the task automation via crontab by running `./gravity-sync.sh automate` which will simply ask how often you'd like to run the script per hour, and then create the entry for you.
- If you've already configured an entry for this manually with a prior version, the script should detect this and ask that you manually remove it or edit it via crontab -e. I'm hesitant to delete existing entries here, as it could potentially remove something unrelated to Gravity Sync.

**Bug Fixes**

- Changes method for pulling development branch updates via the beta function.
- Cleanup of various exit commands.

## 1.4
### The Configuration Release

**Features**
- Adds new `./gravity-sync config` feature to simplify deployment!
- Adds variables for SSH settings.
- Rearranges functions, which impacts nothing.
- All new and exciting code comments.
- No new Star Trek references.

#### 1.4.1
- Adds variables for custom log locations to `gravity-sync.conf`, see `.example` file for listing.

### 1.4.3
- Bug fixes around not properly utilizing custom SSH keyfile.

## 1.0
### The Initial Release**

No version control, variables or anything fancy. It only worked if everything was exactly perfect.

```
echo 'Copying gravity.db from HA primary'
rsync -e 'ssh -p 22' ubuntu@192.168.7.5:/etc/pihole/gravity.db /home/pi/gravity-sync
echo 'Replacing gravity.db on HA secondary'
sudo cp /home/pi/gravity-sync/gravity.db /etc/pihole/ echo 'Reloading configuration of HA secondary FTLDNS from new gravity.db'
pihole restartdns reload-lists
echo 'Cleaning up things'
mv /home/pi/gravity-sync/gravity.db /home/pi/gravity- sync/gravity.db.last
```

For real, that's it. 7 lines.
