Castellan
0.16.1
The buttons on a role card are all the same height.
What changed
- On every role card, Start and Stop are now the same size as Open, Update, Hire and Employee management, so the row of buttons lines up instead of two standing taller than the rest. Buttons across the page keep one height whether they open a page or do something.
Before you update
- Nothing: it updates itself as usual.
0.15.7
Your own agents can be hired from their role cards, the first time too.
What's new
- An agent that is yours alone (on this PC, built by the Steward from its clone) now shows Hire on its role card and in the hire popup when it isn't installed yet. Hire asks the Steward to build and install it, and the page follows the install as for any hire. Before, its first install was a command run by hand.
What changed
- It is offered only where the Steward is installed and looks after that agent; once installed, the Steward keeps it up to date, as before.
Before you update
- Update the Steward to 0.27.2 or later first: Hire asks it for the install.
0.15.6
The setup shows Castellan's licence terms, and installs once you accept them.
What's new
- Setting Castellan up now shows its licence terms (the EULA) right after the welcome. Next waits until you tick I accept the licence terms. They're the same terms as on castellan-software.com/terms.
- From a terminal, the setup asks you to accept them before it installs anything.
setup.exe termsshows them, and--accept-termsaccepts them for an unattended setup. With--yesalone, nothing is installed.
Before you update
- Nothing: it updates itself as usual. The terms are asked only when you run the setup.
0.15.5
It carries the Steward's kit 2.36.1: the parts every agent of the manor shares.
What changed
- The Steward's kit 2.36.1: GenieX 0.8.0 is the NPU's server on a Snapdragon.
Before you update
- Nothing: it updates itself as usual. This kit comes after 2.36.0; 2.33.0 (Steward 0.19.4) is still to be released and doesn't depend on it.
0.15.4
Uninstalling frees your licence's place, Settings says plainly where your backups are, and installs are followed right on Windows in any language.
What changed
- Uninstalling Castellan without keeping its data now gives this PC's place on your licence back first, so another PC can use it. If the licence service can't be reached, the uninstall says so and carries on; another PC can free the place later from Settings > Licence.
- Settings shows the full path of the folder your settings backups go to until you choose one: on this PC only, in a folder OneDrive never copies.
- Moving old backups out of Documents\Manor backups is more careful: one copied to another drive is checked byte for byte before the old one is removed, and one that can't be moved stays where it was and is tried again the next time Castellan starts.
- Castellan reads whether an install is running from Task Scheduler's own state, not from the English word "Running", so updates and hiring are followed the same way on Windows in any language.
Before you update
- Nothing: it updates itself as usual. Your settings backups go to Castellan\Backups in your local app data, on this PC only (Settings shows the full path), unless you chose a folder in Back up to, which is kept. Backups still in Documents\Manor backups move there by themselves.
