-v2 code example:
-```go
-package main
-
-import (
-	"context"
-
-	qdb "github.com/questdb/go-questdb-client/v2"
-)
-
-func main() {
-	// Connect to QuestDB running on 127.0.0.1:9009 (ILP/TCP)
-	sender, err := qdb.NewLineSender(context.TODO())
-	// ...
-	defer sender.Close()
-	// ...
-}
-```
-
-Migrated v3 code:
-```go
-package main
-
-import (
-	"context"
-
-	qdb "github.com/questdb/go-questdb-client/v3"
-)
-
-func main() {
-	// Connect to QuestDB running on 127.0.0.1:9000 (ILP/HTTP)
-	sender, err := qdb.NewLineSender(context.TODO(), qdb.WithHTTP())
-	// Alternatively, you can use the LineSenderFromConf function:
-	// sender, err := qdb.LineSenderFromConf(ctx, "http::addr=localhost:9000;")
-	// ...
-	// or you can export the "http::addr=localhost:9000;" config string to
-	// the QDB_CLIENT_CONF environment variable and use the LineSenderFromEnv function:
-	// sender, err := qdb.LineSenderFromEnv(ctx)
-	// ...
-	defer sender.Close(context.TODO())
-	// ...
-}
-```
-
-Note that the migrated code uses the HTTP sender instead of the TCP one.
