Change array parameter serialization for v2 endpoints to use indexed format (e.g., ?include[0]=foo&include[1]=bar) instead of the repeated parameter format (e.g., ?include=foo&include=bar). This aligns v2 behavior with v1 for consistency. Changes: - Modified Util.php flattenParamsList to always use indexed format - Updated tests to expect indexed format for v2 arrays 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]> Committed-By-Agent: claude

Why?
Stripe has updated how array parameters are handled in
GETandDELETEmethods to/v2endpoints. Previously, the SDKs were serializing them with repeated parameter format (e.g.,?include=foo&include=bar) since that is was the API expected. While that format is still accepted, it is deprecated. Instead, we will serialize array parameters to use indexed format (e.g.,?include[0]=foo&include[1]=bar), which is the preferred method going forward. This aligns v2 behavior with v1 for consistency.What?
Util.phpflattenParamsListto always use indexed formatChangelog
RetrieveandListcalls for/v2endpoints now use indexed format (e.g.,?include[0]=foo&include[1]=bar) instead of repeated parameter format (e.g.,?include=foo&include=bar) when communicating with the Stripe API. This may break any unit tests that expect the latter behavior when setting up a mock server. Instead, they should now expect the former.
