**Important Notes:**
* This release introduces a new type (see the section on Structured Dataset below). Naturally this means changes to the IDL, which means that tools that work with Flyte entities encode the new type will also need to be updated. For most readers of this note, that means `FlyteRemote` (which comes with `flytekit`).
* **Note:** This feature is turned off by default (will be on by default at the 1.0.0 release) because this new type needs a Propeller and Admin upgrade. Turn it on via the env var `FLYTE_SDK_USE_STRUCTURED_DATASET=TRUE`. See more below.
* This release also removes the legacy API (see more below). Because of this change, if you bump up your `flytekit` version, you'll also need to bump all your `flytekitplugins-` to the same version as well, otherwise you might see missing imports.
* Lastly, this release skips a few version numbers from 0.26 to 0.30 for future-proofing.

Notable Changes
New Type - Structured Dataset
To handle the new type, you will need to be on Propeller version v0.16.14 and Admin version v0.6.78 or later. Because of this backend upgrade restriction, we've decided to feature-gate this new type. To turn this feature on, you will need to set the environment variable:
FLYTE_SDK_USE_STRUCTURED_DATASET=TRUE
Note that we'll be turning on this feature by default at the 1.0.0 release of flytekit (and Flyte generally) in Q2.
If turned on, dataframe types (e.g. `pandas` or `pyspark` and others) will be converted into the new `StructuredDataset` [type](https://github.com/flyteorg/flyteidl/pull/227/files#diff-da0cd41ae99f181280058bc79cbc3f3565a22039fbefcbe5f191bc2780d72735R46) and [literal](https://github.com/flyteorg/flyteidl/pull/227/files#diff-e9c7f9528aac9670ee8251a31dd27a04b07bd1afbb195f053ad0182e39eb2119R66).
Please see the [PR](https://github.com/flyteorg/flytekit/pull/785) description for the full details, extension interfaces, and design, as well as the upcoming OSS meeting (Tuesday Feb. 8th) for a deeper discussion. The design doc also is [here](https://docs.google.com/document/d/1-t8C4vW_RhrJoC5Ju16fmqpyOvsCRb3XmulLLo5VX0E/edit).
Removal of legacy API
We've removed the old [legacy API](https://github.com/flyteorg/flytekit/pull/807). This helped remove over 20k lines of code, reduces complexity, and makes the ongoing maintenance load lighter. As part of this cleanup however, some functionality in `flyte-cli` and (`pyflyte`) will be going away. Most of this functionality though has been in `flytectl` for some time. Please let us know if you have any problems.
`flyte-cli`
* `launch-task`
* `execute-launch-plan`
* `watch-execution`
* `relaunch-execution`
These were all commands that relied on the old typing system that was removed.
`pyflyte`
* `register` and `fast-register`
* `launchplan` commands
These were commands that have been deprecated for some time because they communicated with the Flyte control plane (which has been taken over by `flytectl` and/or relied on the old typing system that was removed.)
