+- `get_record_table()` returns now 4 new columns: `longitude`, `latitude` (deployment coordinates), `clock` (clock time of the observation in radians) and `solar` (sun time of the observation in radians) (#341).

 # camtraptor 0.26.0
 
 - `get_custom_effort()` returns now the effort for each deployment separately (#333). The returned data frame has two new columns: `deploymentID` and `locationName`.
