## What changed?
<!-- Describe what has changed in this PR -->
Remove license header from every file. Because it is really hard to
follow in this PR here is the summary:
1. License header is removed from all `.go` and `.proto` files
:fireworks::fireworks:🎆.
2. `LICENSE` file in the root directory has only Temporal and Uber
copyrights.
3. 5 other `LICENSE` files added to the packages which have copyrights
different from Temporal and Uber: Datadog, Xargin, "Mat Ryer, Tyler
Bunnell and contributors".
4. `license_file` flag is removed from all code generation tools.
5. `copyright_file` flag is removed from `go:generate mockgen`
directive.
6. All copyright related targets are removed from `Makefile`.
7. Updated Temporal copyright year to 2025 everywhere.
## Why?
<!-- Tell your future self why have you made these changes -->
I double checked with legal department that it is not needed to have
license header in every file. One file per repo is enough. I put all
copyrights to the root `LICENSE` file and removed header from all other
files. Also updated tools and `Makefile`.
## What changed?
- CHASM nodes are now internally represented as split distinctly between
Metadata and Data parts.
- Additional columns were added to SQL plugins, bumping the SQL schema
- No change was made to the Cassandra columns; instead, ExecutionManager
ensures that when running on Cassandra, the entire node continues to be
represented in a single blob, to avoid lowering Cass performance
post-change.
## Why?
Before, a ChasmNode contained both its metadata fields, and the user
data blob. Decoding a ChasmNode would cause an additional (often large,
relative to the metadata) allocation to store the inner data blob, as
well as additional memcpys while encoding/decoding. With this change,
the data field can be passed along as-is, opaquely, while the metadata
field can be decoded without additional penalty from a large data blob.
## How did you test it?
- Updated tests

## What changed?
SQL persistence support has been added for CHASM nodes.
- A new `chasm_node_maps` table has been added to SQL schemas
- SQL test suites updated
- SQL execution manager/util updated
- SQL plugins for `chasm_node_map` table
## Why?
- We've landed Cassandra persistence support for CHASM nodes, this
brings SQL support up to parity.
## How did you test it?
- New tests ran on all SQL plugins
- `go test -v ./...`
## Potential risks
- No application paths write chasm_node_maps yet, but change does
involve a schema change

## What changed?
Make import formatting a part of the build, and test validity with
"ensure-no-changes" target
## Why?
So we never discuss import order again (hopefully)
## How did you test it?
its a build change, so the build will test it!
## Potential risks
As long as build works, the only thing I risk is the ire of coworker who
want imports to be different ;)

## Is hotfix candidate?
No
* Revert "Capture UpdateInfos in MutableState mutation (#4372)"
This reverts commit c78ee02eee.
* Revert "Adds update state indexing to MutableState (#4224)"
This reverts commit f8303d8e7e.
* Add UpdateInfo map to WorkflowExecutionInfo
This inlines the UpdateInfo index into the pre-existing execution blob
so that downstream persistence implementations won't see any change.
Add UpdateInfo records to MutableState
A mechanism for storing pointers into the workflow history representing
update accepted or completed events. Storage added for Cassandra,
PosgtreSQL, MySQL, and SQLite.
* Import SQLite driver from Temporalite: these files originated from https://github.com/DataDog/temporalite
* Add SQLite driver layer & UT
* Use mattn SQLite driver
NOTE: SQLite support is still in development stage
