[meta] Breaking changes

[taion]

Wanted to open a meta issue to keep track of things we might want to break (but not before deprecating if possible):

Major

• Remove pushState(state, path, query) and replaceState(state, path, query) in favor of push({path, query, state}) and replace({path, query, state}) (Accept objects in push and replace #141, Deprecate pushState/replaceState, use push/replace instead #162)

Minor

• Swap out qs for query-string as default query string handler (Use query-string instead of qs #121)
• Change useQueries to replace location.search instead of appending (workaround in Accept objects in push and replace #141)

Let's include all of this in a 1.14 release. I'll make a PR to switch from qs to query-string that includes a warning for people using nested objects in their queries.

[mjackson]

I should note that after we ship 1.14 I think we're ready to focus in on v2 so we can cut loose all these deprecation warnings.

[mjackson]

All of this was shipped in 1.14. I think we can close now.

Thanks!
