|
|||
* The codebase was moved to a more tree-ish approach, where several
|
||||
subdirectories were introduced for different types of crates
|
||||
* The documentation got a major overhaul and was partly rewritten
|
||||
* The logger is now configurable via the config file.
|
||||
* New
|
||||
* `libimagentrygps` was introduced
|
