 **BREAKING CHANGES:*** Version 3.0.0 is here. It includes _a lot_ of changes including a few that break the API.

See `MIGRATION_GUIDE.md` for more information on updating your code.
 
-**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/).  As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected.  There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API.  In the short term, please make sure your implementation verifies the `alg` is what you expect.

+* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
 * OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
 * Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.

-`strict=true` enables a driver-side strict mode in which MySQL warnings are treated as errors. This mode should not be used in production as it may lead to data corruption in certain situations.
 
-A server-side strict mode, which is safe for production use, can be set via the [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html) system variable.
+`rejectReadOnly=true` causes the driver to reject read-only connections. This
+is for a possible race condition during an automatic failover, where the mysql
+client gets connected to a read-only replica after the failover.
+
+Note that this should be a fairly rare case, as an automatic failover normally
+happens when the primary is down, and the race condition shouldn't happen
+unless it comes back up online as soon as the failover is kicked off. On the
+other hand, when this happens, a MySQL application can get stuck on a
+read-only connection until restarted. It is however fairly easy to reproduce,
+for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
+
+If you are not relying on read-only transactions to reject writes that aren't
+supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
+is safer for failovers.
+
+Note that ERROR 1290 can be returned for a `read-only` server and this option will
+cause a retry for that error. However the same error number is used for some
+other cases. You should ensure your application will never cause an ERROR 1290
+except for `read-only` mode when enabling this option.

The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.

+The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
 
 However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.

 To define custom names for fields, use a struct tag "schema". To not populate certain fields, use a dash for the name and it will be ignored:
