 # Lithic Python API library
 
-> **Migration Guide**
->
-> We've made some major improvements to how you pass arguments to methods which will require migrating your existing code.
->
-> If you want to migrate to the new patterns incrementally you can do so by installing `v0.5.0`. This release contains both
-> the new and old patterns with a backwards compatibility layer.
->
-> You can find a guide to migrating in [this document](#migration-guide).

 By default the library closes underlying HTTP connections whenever the client is [garbage collected](https://docs.python.org/3/reference/datamodel.html#object.__del__). You can manually close the client using the `.close()` method if desired, or with a context manager that closes when exiting.
 
-# Migration guide
-
-This section outlines the features that were deprecated in `v0.5.0`, and subsequently removed in `v0.6.0` and how to migrate your code.
-
-## Breaking changes
-
-### TypedDict → keyword arguments
-
-The way you pass arguments to methods has been changed from a single `TypedDict` to individual arguments. For example, this snippet:
-
-```python
-card = await client.cards.create({"type": "VIRTUAL"})
-```
-
-Now becomes:
-
-```python
-card = await client.cards.create(type="VIRTUAL")
-```
-
-#### Migrating
-
-The easiest way to make your code compatible with this change is to add `**{`, for example:
-
-```diff
-- card = await client.cards.create({'type': 'VIRTUAL'})
-+ card = await client.cards.create(**{'type': 'VIRTUAL'})
-```
-
-However, it is highly recommended to completely switch to explicit keyword arguments:
-
-```diff
-- card = await client.cards.create({'type': 'VIRTUAL'})
-+ card = await client.cards.create(type='VIRTUAL')
-```
-
-### Named path arguments
-
-All but the last path parameter must now be passed as named arguments instead of positional arguments, for example, for a method that calls the endpoint `/account_holders/{account_holder_token}/documents/{document_token}` you would've been able to call the method like this:
-
-```python
-card = await client.account_holders.retrieve(
-    "account_holder_token", "my_document_token"
-)
-```
-
-But now you must call the method like this:
-
-```python
-card = await client.account_holders.retrieve(
-    "my_document_token", account_holder_token="account_holder_token"
-)
-```
-
-If you have type checking enabled in your IDE it will tell you which parts of your code need to be updated.
-
-### Request options
-
-You used to be able to set request options on a per-method basis, now you can only set them on the client. There are two methods that you can use to make this easy, `with_options` and `copy`.
-
-If you need to make multiple requests with changed options, you can use `.copy()` to get a new client object with those options. This can be useful if you need to set a custom header for multiple requests, for example:
-
-```python
-copied = client.copy(default_headers={"X-My-Header": "Foo"})
-card = await copied.cards.create(type="VIRTUAL")
-await copied.cards.provision(card.token, digital_wallet="GOOGLE_PAY")
-```
-
-If you just need to override one of the client options for one request, you can use `.with_options()`, for example:
-
-```python
-await client.with_options(timeout=None).cards.create(type="VIRTUAL")
-```
-
-It should be noted that the `.with_options()` method is simply an alias to `.copy()`, you can use them interchangeably.
-
-You can pass nearly every argument that is supported by the Client `__init__` method to the `.copy()` method, except for `proxies` and `transport`.
-
-```python
-copied = client.copy(
-    api_key="...",
-    environment="sandbox",
-    timeout=httpx.Timeout(read=10),
-    max_retries=5,
-    default_headers={
-        "X-My-Header": "value",
-    },
-    default_query={
-        "my_default_param": "value",
-    },
-)
-```
-
-## New features
-
-### Pass custom headers
-
-If you need to add additional headers to a request you can easily do so with the `extra_headers` argument:
-
-```python
-card = await client.cards.create(
-    type="VIRTUAL",
-    extra_headers={
-        "X-Foo": "my header",
-    },
-)
-```
-
-### Pass custom JSON properties
-
-You can add additional properties to the JSON request body that are not included directly in the method definition through the `extra_body` argument. This can be useful when there are in new properties in the API that are in beta and aren't in the SDK yet.
-
-```python
-card = await client.cards.create(
-    type="VIRTUAL",
-    extra_body={
-        "special_prop": "foo",
-    },
-)
-# sends this to the API:
-# {"type": "VIRTUAL", "special_prop": "foo"}
-```
-
-### Pass custom query parameters
-
-You can add additional query parameters that aren't specified in the method definition through the `extra_query` argument. This can be useful when there are any new/beta query parameters that are not yet in the SDK.
-
-```python
-card = await client.cards.create(
-    type="VIRTUAL",
-    extra_query={
-        "special_param": "bar",
-    },
-)
-# makes the request to this URL:
-# https://api.lithic.com/v1/cards?special_param=bar
-```
-
-## Rich `date` and `datetime` types
-
-We've improved the types for response fields / request params that correspond to `date` or `datetime` values!
-
-Previously they were just raw strings but now response fields will be instances of `date` or `datetime`.
-
-This means that if you're working with these fields and parsing them into `datetime` instances manually you will have to remove
-any code that performs said parsing.
-
-```diff
-card = client.cards.retrieve('<token>')
-- created = datetime.fromisoformat(card.created_at)
-+ created = card.created_at
-print(created.month)
-```
-
-For request params you can continue to pass in strings if you want to use a datetime library other than the standard library version but if you
-were writing code that looked like this:
-
-```py
-dt = datetime(...)
-for card in client.cards.list(begin=dt.isoformat()):
-  ...
-```
-
-You can remove the explicit call to `isoformat`!
-
-```diff
-dt = datetime(...)
-- for card in client.cards.list(begin=dt.isoformat()):
-+ for card in client.cards.list(begin=dt):
-  ...
-```
