# Slic3r PE 1.40 configuration update
|
||
|
||
Slic3r PE 1.40.0 comes with a major re-work of the way configuration presets work.
|
||
There are three new features:
|
||
|
||
+ A two-tier system of presets being divided into _System_ and _User_ groups
|
||
+ Configuration snapshots
|
||
+ Configuration updating from the internet
|
||
|
||
## System and User presets
|
||
|
||
- _System preset_: These are the presets that come with Slic3r PE installation. They come from a vendor configuration bundle (not individual files like before). They are **read-only** – a user cannot modify them, but may instead create a derived User preset based on a System preset
|
||
- _User preset_: These are regular presets stored in files just like before. Additionally, they may be derived (inherited) from one of the System presets
|
||
|
||
A derived User preset keeps track of which settings are inherited from the parent System preset and which are modified by the user. When a system preset is updated (either via installation of a new Slic3r or automatically from the internet), in a User preset the settings that are modified by the user will stay that way, while the ones that are inherited reflect the updated System preset.
|
||
|
||
This system ensures that we don't overwrite user's settings when there is an update to the built in presets.
|
||
|
||
Slic3r GUI now displays accurately which settings are inherited and which are modified.
|
||
A setting derived from a System preset is represented by green label and a locked lock icon:
|
||
|
||
|
||
|
||
A settings modified in a User preset has an open lock icon:
|
||
|
||
|
||
|
||
Clicking the open lock icon restores the system setting.
|
||
|
||
Additionally, any setting that is modified but not yet saved onto disk is represented by orange label and a back-arrow:
|
||
|
||
|
||
|
||
Clicking the back-arrow restores the value that was previously saved in this Preset.
|
||
|
||
## Configuration snapshots
|
||
|
||
Configuration snapshots can now be taken via the _Configuration_ menu.
|
||
A snapshot contains complete configuration from the point when the snapshot was taken.
|
||
Users may move back and forth between snapshots at will using a dialog:
|
||
|
||
|
||
|
||
|
||
# Updating from the internet
|
||
|
||
Slic3r PE 1.40.0 checks for updates of the built-in System presets and downloads them.
|
||
The first-time configuration assistant will ask you if you want to enable this feature - it is **not** mandatory.
|
||
|
||
Updates are checked for and downloaded in the background. If there's is an update, Slic3r will prompt about it
|
||
next time it is launched, never during normal program operation. An update may be either accepted or refused.
|
||
Before any update is applied a configuration snapshot (as described above) is taken.
