* [19](https://github.com/sdss/cherno/pull/19) Major rewrite of the guide algorithm, now using Conor's `SolvePointing` class.
🔧 Fixed
* Fix a case in which the exposure time could increase in an uncontrolled way.
0.6.9
✨ Improved
* [18](https://github.com/sdss/cherno/pull/18) Two efficiency improvements: * The `wait_time` is only used when a correction has actually applied. Otherwise the next iteration start immediately. * Allow to specify a `--dynamic-exposure-time` that combined with `--max-exposure-time` can be used to set an initial short exposure time. If the field fails to solve the exposure time is automatically increased for the following iteration up to `--max-exposure-time`.
🏷️ Changed
* Set integral term for RA and Dec at APO to 0.01.
0.6.8
🔧 Fixed
* Upgraded SQLAlchemy to `^2.0.0`. It seems that Pandas now requires `>=2.0` to run `read_sql` using a connection URI. * Increased scale factor tolerance and `max_delta_scale_ppm` for LCO to account for the new IMB position and plate scale. * Fixed docs building.
0.6.7
✨ Improved
* [17](https://github.com/sdss/cherno/pull/17) Allow to select what cameras to use for guiding or focusing by invoking `cherno set cameras [guide|focus] gfa2 gfa3 ...` (same as `cherno set cameras` but only affects guiding or focusing).
0.6.6
✨ Improved
* Added a warning when a non-zero offset is used. * Updated Pandas to 2.x. * Bump `coordio` to 1.9.2 to use new `sdss-sep` package.
0.6.5
🔧 Fixed
* Bump `sdsstools` to 1.5.5 to prevent an issue when pickling the `Guider` object in multiprocessing.
