# Changelog



## v0.1.13 (2021-12-28)



- Improvement: Use new Fly.io internal DNS feature to connect to the "nearest" replica database when deployed to a region other than the primary region.



Solves a problem when an instance is deployed to a backup region where the replica isn't deployed. Also helps make more resilient in going to closest replica it can find should any other problems prevent the expected one to be available.



## v0.1.12 (2021-11-16)



- Fix: For dev and test environments, return `nil` for customized DATABASE_URL setting. This removes requirement for setting the DATABASE_URL in an ENV for local dev and test. Additionally, this fixes an issue where the dev database was being used when running tests.

- Added usage documentation in the README under "Config Files"

- New usage documentation section in README titled "Releases and Migrations"



## v0.1.11 (2021-11-06)



- Enhancement: Internally, improved logic around polling the database for the replication status. Only polls when there is a request for replication notification.



## v0.1.10 (2021-11-04)



### Enhancements



- **Breaking change** - Added `rewrite_db_url` config option. Removes reliance on ENV setting MIX_ENV.



To use, in either `config/prod.exs` or `config/runtime.exs`, instruct the library to rewrite the `DATABASE_URL` used when connecting to the database. It takes into account which region is your primary region and attempts to connect to the primary or the replica accordingly.



```elixir

config :fly_postgres, rewrite_db_url: true

```
