Operations

- Updating `nightly` frequency (temp)

Added

- Tutorial for hybrid neural network using Covalent, AWSBatch, and Qiskit Runtime.
- Environment variable that users can set to specify the location where Covalent can find their defined executors.
- Task group id in Electrons.
- Reconstruct postprocessing method.

Fixed

- Doubling of nodes that are added to the transport graph.
- Ensure postprocessing node end time is added as the workflow end time.
- Functional tests
- Custom executor how to guide, and its loading mechanism in covalent server.
- Broken postprocessing unit test.

Added

- Postprocessing as electrons.
- Postprocessing class in `postprocessing.py` module for all the different postprocessing helper methods and algorithms.

Changed

- Postprocessing logic.
- Sublattice logic. Sublattices are now treated as electrons. Once the transport graph has been built, the status get changed to `DISPATCHING` at which point it is executed as another workflow.

Removed

- Postprocessing from runners.

Docs

- Updated How-to documents.
- Port of Pennylane's Univariate QVR tutorial using Covalent to this repo.
- Adding troubleshooting guide to RTD's
- Added a note to First Experiment offering initial intro to executors.
- Adding Google Batch executor plugin RTD

Docs

- Adding `cancellation` RTD text files

Added

- `disable_run` option added to enable "saving-only" option on covalent server and not executing the workflow
- `register_triggers`, `stop_triggers` functions added to `LocalDispatcher` class
- `triggers` parameter to the lattice metadata
- `BaseTrigger`, `DirTrigger`, `TimeTrigger` classes added available to be assigned to any lattice enabling the triggers feature
- `TriggerLoader` class added enabling loading of any kind of triggers including user defined ones without requiring installation
- CLI options to start covalent server in triggers only, and no triggers mode
- `is_pending` option added during redispatch to resume execution of a previously "saved-only", i.e pending workflow
- API routes added for Triggers server

Changed

- Modified `ct.get_result` to allow for status only requests

Fixed

- UI crashing if time values are null
- No longer adding "http://" every time a dispatcher address is provided in local dispatcher class in order to use the provided address exactly

Docs

- Added documentation for "Triggers" and a separate section for similar "Features"
- Tutorial guidelines

Tests

- Updated and added tests to account for all of the above triggers related changes

Operations

- Lowering number of jest workers as an attempt to fix flaky UI functional tests
- Added exception for nightly to pass if conda release fails

Docs

- Redispatch API section.
- Add how to for redispatch.
- Mention redispatch in the concepts section.
- Update `AWS Lambda` executor RTD with steps to extend the base executor image for installing custom packages

Changed
