+Fix many schema and fragment lifecycle issues, for all contexts except for schema updates for url schemas.
+Note: this makes `cacheSchemaForLookup` enabled by default again for schema first contexts.
+
+this fixes multiple cacheing bugs, on writing some in-depth integration coverage for the LSP server.
+it also solves several bugs regarding loading config types, and properly restarts the server when there are config changes
+
+### Bugfix Summary
+
+- jump to definition in embedded files offset bug
+- cache invalidation for fragments
+- schema cache invalidation for schema files
+- schema definition lookups & autocomplete crossing into the wrong workspace
+
+### Known Bugs Fixed
+
+- #3318
+- #2357
+- #3469
+- #2422
+- #2820
+- many others to add here...
+
+### Test Improvements
+
+- new, high level integration spec suite for the LSP with a matching test utility
+- more unit test coverage
+- **total increased test coverage of about 25% in the LSP server codebase.**
+- many "happy paths" covered for both schema and code first contexts
+- many bugs revealed (and their source)

 ## Frequently Asked Questions
 
-<span id="legacy" />
-
-### I can't load `.graphqlconfig` files anymore
-
-> Note: this option has been set to be enabled by default, however
-> `graphql-config` maintainers do not want to continue to support the legacy
-> format (mostly kept for companies where intellij users are stuck on the old
-> config format), so please migrate to the new `graphql-config` format as soon
-> as possible!
-
-If you need to use a legacy config file, then you just need to enable legacy
-mode for `graphql-config`:
-
-```json
-"graphql-config.load.legacy": true
-```
-
-### Go to definition is not working for my URL
-
-You can try the new experimental `cacheSchemaFileForLookup` option. NOTE: this
-will disable all definition lookup for local SDL graphql schema files, and
-_only_ perform lookup of the result an SDL result of `graphql-config`
-`getSchema()`
-
-To enable, add this to your settings:
-
-```json
-"vscode-graphql.cacheSchemaFileForLookup": true,
-```
-
-you can also use graphql config if you need to mix and match these settings:

+Please refer to the `vscode-graphql-syntax` reference files ([js](https://github.com/graphql/graphiql/blob/main/packages/vscode-graphql-syntax/tests/__fixtures__/test.js),[ts](https://github.com/graphql/graphiql/blob/main/packages/vscode-graphql-syntax/tests/__fixtures__/test.ts),[svelte](https://github.com/graphql/graphiql/blob/main/packages/vscode-graphql-syntax/tests/__fixtures__/test.svelte),[vue](https://github.com/graphql/graphiql/blob/main/packages/vscode-graphql-syntax/tests/__fixtures__/test.vue)) to learn our template tag, comment and other graphql delimiter patterns for the file types that the language server supports. The syntax highlighter currently supports more languages than the language server. If you notice any places where one or the other doesn't work, please report it!
 
 ## Known Issues
 
-- the output channel occasionally shows "definition not found" when you first
-  start the language service, but once the definition cache is built for each
-  project, definition lookup will work. so if a "peek definition" fails when you
-  first start the editor or when you first install the extension, just try the
-  definition lookup again.
+- the locally generated schema file for definition lookup currently does not re-generate on schema changes. this will be fixed soon.
+- multi-root workspaces support will be added soon as well.
+- some graphql-config options aren't always honored, this will also be fixed soon

 ### Bugfix Summary
 
-- jump to definition in embedded files offset bug
-- cache invalidation for fragments
-- schema cache invalidation for schema files
-- schema definition lookups & autocomplete crossing into the wrong workspace
+- configurable polling updates for network and other code first schema configuration, set to a 30s interval by default. powered by `schemaCacheTTL` which can be configured in the IDE settings (vscode, nvim) or in the graphql config file. (1)
+- jump to definition in embedded files offset bug, for both fragments and code files with SDL strings
+- cache invalidation for fragments (fragment lookup/autcoomplete data is more accurate, but incomplete/invalid fragments still do not autocomplete or validate, and remember fragment options always filter/validate by the `on` type!)
+- schema cache invalidation for schema files - schema updates as you change the SDL files, and the generated file for code first by the `schemaCacheTTL` setting
+- schema definition lookups & autocomplete crossing over into the wrong project
+
+**Notes**
+
+1. If possible, configuring for your locally running framework or a registry client to handle schema updates and output to a `schema.graphql` or `introspection.json` will always provide a better experience. many graphql frameworks have this built in! Otherwise, we must use a lazy polling approach.

+### What's next?
+
+Another stage of the rewrite is already almost ready. This will fix even more bugs and improve memory usage, eliminate redundant parsing and ensure that graphql config's loaders do _all_ of the parsing and heavy lifting, thus honoring all the configs as well. It also significantly reduces the code complexity.
+
+There is also a plan to match Relay LSP's lookup config for either IDE (vscode, nvm, etc) settings as they provide, or by loading modules into your `graphql-config`!

-bugfix to completion for SDL type fields
+Fixes several issues with Type System (SDL) completion across the ecosystem:
+
+- restores completion for object and input type fields when the schema context is not parseable
+- correct top-level completions for either of the unknown, type system or executable definitions. this leads to mixed top level completions when the document is unparseable, but now you are not seemingly restricted to only executable top level definitions
+- `.graphqls` ad-hoc standard functionality remains, but is not required, as it is not part of the official spec, and the spec also allows mixed mode documents in theory, and this concept is required when the type is unknown

If possible, configuring for your locally running framework or a schema registry client to handle schema updates and output to a `schema.graphql` or `introspection.json` will always provide a better experience. many graphql frameworks have this built in! Otherwise, we must use this new lazy polling approach if you provide a url schema (this includes both introspection URLs and remote file URLs, and the combination of these).

 Fixes several issues with Type System (SDL) completion across the ecosystem:
 
-- restores completion for object and input type fields when the schema context is not parseable
+- restores completion for object and input type fields when the document context is not detectable or parseable
 - correct top-level completions for either of the unknown, type system or executable definitions. this leads to mixed top level completions when the document is unparseable, but now you are not seemingly restricted to only executable top level definitions
 - `.graphqls` ad-hoc standard functionality remains, but is not required, as it is not part of the official spec, and the spec also allows mixed mode documents in theory, and this concept is required when the type is unknown

+'graphql-language-service-server': minor
+'vscode-graphql': patch

+
+Introduce `locateCommand` based on Relay LSP `pathToLocateCommand`:
+
+Now with `<graphql config>.extensions.languageService.locateCommand`, you can specify either the [existing signature](https://marketplace.visualstudio.com/items?itemName=meta.relay#relay.pathtolocatecommand-default-null) for relay, with the same callback parameters and return signature.
+
+Relay LSP currently supports `Type` and `Type.field` for the 2nd argument. Ours also returns `Type.field(argument)` as a point of reference. It works with object types, input types, fragments, executable definitions and their fields, and should work for directive definitions as well.
+
+In the case of unnamed types such as fragment spreads, they return the name of the implemented type currently, but I'm curious what users prefer here. I assumed that some people may want to not be limited to only using this for SDL type definition lookups. Also look soon to see `locateCommand` support added for symbols, outline, and coming references and implementations.
+
+The module at the path you specify in relay LSP for `pathToLocateCommand` should work as such
+
+```ts
+// import it
+import { locateCommand } from './graphql/tooling/lsp/locate.js';
+export default {
+  languageService: {
+    locateCommand,
+  },
+
+  projects: {
+    a: {
+      schema: 'https://localhost:8000/graphql',
+      documents: './a/**/*.{ts,tsx,jsx,js,graphql}',
+    },
+    b: {
+      schema: './schema/ascode.ts',
+      documents: './b/**/*.{ts,tsx,jsx,js,graphql}',
+    },
+  },
+};
+```
+
+```ts
+// or define it inline
+
+import { type LocateCommand } from 'graphql-language-service-server';
+
+// relay LSP style
+const languageCommand = (projectName: string, typePath: string) => {
+  const { path, startLine, endLine } = ourLookupUtility(projectName, typePath);
+  return `${path}:${startLine}:${endLine}`;
+};
+
+// an example with our alternative return signature
+const languageCommand: LocateCommand = (projectName, typePath, info) => {
+  // pass more info, such as GraphQLType with the ast node. info.project is also available if you need it
+  const { path, range } = ourLookupUtility(
+    projectName,
+    typePath,
+    info.type.node,
+  );
+  return { uri: path, range }; // range.start.line/range.end.line
+};
+
+export default {
+  languageService: {
+    locateCommand,
+  },
+  schema: 'https://localhost:8000/graphql',
+  documents: './**/*.{ts,tsx,jsx,js,graphql}',
+};
+```
+
+Passing a string as a module path to resolve is coming in a follow-up release. Then it can be used with `.yml`, `.toml`, `.json`, `package.json#graphql`, etc
+
+For now this was a quick baseline for a feature asked for in multiple channels!
+
+Let us know how this works, and about any other interoperability improvements between our graphql LSP and other language servers (relay, intellij, etc) used by you and colleauges in your engineering organisations. We are trying our best to keep up with the awesome innovations they have 👀!
