+# Changelog
+
+## Unreleased
+
+- "I am running away from my responsibilities. And it feels good." – Michael Scott, Season 4, "Money"
+
+## v0.6.1
+
+- fix: Use NewEvent to init Event struct (#220)
+
+_NOTE:_
+A change introduced in v0.6.0 with the intent of avoiding allocations made a
+pattern used in official examples break in certain circumstances (attempting
+to write to a nil map).
+This release reverts the change such that maps in the Event struct are always
+allocated.
+
+## v0.6.0
+
+- feat: Read module dependencies from runtime/debug (#199)
+- feat: Support chained errors using Unwrap (#206)
+- feat: Report chain of errors when available (#185)
+- **[breaking]** fix: Accept http.RoundTripper to customize transport (#205)
+  Before the SDK accepted a concrete value of type `*http.Transport` in
+  `ClientOptions`, now it accepts any value implementing the `http.RoundTripper`
+  interface. Note that `*http.Transport` implements `http.RoundTripper`, so most
+  code bases will continue to work unchanged.  
+  Users of custom transport gain the ability to pass in other implementations of
+  `http.RoundTripper` and may be able to simplify their code bases.
+- fix: Do not panic when scope event processor drops event (#192)
+- **[breaking]** fix: Use time.Time for timestamps (#191)  
+  Users of sentry-go typically do not need to manipulate timestamps manually.
+  For those who do, the field type changed from `int64` to `time.Time`, which
+  should be more convenient to use. The recommended way to get the current time
+  is `time.Now().UTC()`.
+- fix: Report usage error including stack trace (#189)
+- feat: Add Exception.ThreadID field (#183)
+- ci: Test against Go 1.14, drop 1.11 (#170)
+- feat: Limit reading bytes from request bodies (#168)
+- **[breaking]** fix: Rename fasthttp integration package sentryhttp => sentryfasthttp  
+  The current recommendation is to use a named import, in which case existing
+  code should not require any change:
+  ```go
+  package main
+
+  import (
+  	"fmt"
+
+  	"github.com/getsentry/sentry-go"
+  	sentryfasthttp "github.com/getsentry/sentry-go/fasthttp"
+  	"github.com/valyala/fasthttp"
+  )
+  ```
+
+_NOTE:_
+This version includes some new features and a few breaking changes, none of
+which should pose troubles with upgrading. Most code bases should be able to
+upgrade without any changes.
+
+## v0.5.1
+
+- fix: Ignore err.Cause() when it is nil (#160)
+
+## v0.5.0
+
+- fix: Synchronize access to HTTPTransport.disabledUntil (#158)
+- docs: Update Flush documentation (#153)
+- fix: HTTPTransport.Flush panic and data race (#140)
+
+_NOTE:_
+This version changes the implementation of the default transport, modifying the
+behavior of `sentry.Flush`. The previous behavior was to wait until there were
+no buffered events; new concurrent events kept `Flush` from returning. The new
+behavior is to wait until the last event prior to the call to `Flush` has been
+sent or the timeout; new concurrent events have no effect. The new behavior is
+inline with the [Unified API
+Guidelines](https://docs.sentry.io/development/sdk-dev/unified-api/).
+
+We have updated the documentation and examples to clarify that `Flush` is meant
+to be called typically only once before program termination, to wait for
+in-flight events to be sent to Sentry. Calling `Flush` after every event is not
+recommended, as it introduces unnecessary latency to the surrounding function.
+Please verify the usage of `sentry.Flush` in your code base.
+

+
+```go
+sentry.Init(sentry.ClientOptions{
+	Integrations: func(integrations []sentry.Integration) []sentry.Integration {
+		var filteredIntegrations []sentry.Integration
+		for _, integration := range integrations {
+			if integration.Name() == "ContextifyFrames" {

+# `raven-go` to `sentry-go` Migration Guide
+
+## Installation
+
+raven-go
+
+```go
+go get github.com/getsentry/raven-go
+```
+
+sentry-go
+
+```go
+go get github.com/getsentry/sentry-go@v0.0.1
+```
+
+## Configuration
+
+raven-go
+
+```go
+import "github.com/getsentry/raven-go"
+
+func main() {
+    raven.SetDSN("___PUBLIC_DSN___")
+}
+```
+
+sentry-go
+
+```go
+import (
+    "fmt"
+    "github.com/getsentry/sentry-go"
+)
+
+func main() {
+    err := sentry.Init(sentry.ClientOptions{
+        Dsn: "___PUBLIC_DSN___",
+    })
+
+    if err != nil {
+        fmt.Printf("Sentry initialization failed: %v\n", err)
+    }
+}
+```
+
+raven-go
+
+```go
+SetDSN()
+SetDefaultLoggerName()
+SetDebug()
+SetEnvironment()
+SetRelease()
+SetSampleRate()
+SetIgnoreErrors()
+SetIncludePaths()
+```
+
+sentry-go
+
+```go
+sentry.Init(sentry.ClientOptions{
+    Dsn: "___PUBLIC_DSN___",
+    DebugWriter: os.Stderr,
+    Debug: true,
+    Environment: "environment",
+    Release: "release",
+    SampleRate: 0.5,
+    // IgnoreErrors: TBD,
+    // IncludePaths: TBD
+})
+```
+
+Available options: see [Configuration](https://docs.sentry.io/platforms/go/config/) section.
+
+### Providing SSL Certificates
+
+By default, TLS uses the host's root CA set. If you don't have `ca-certificates` (which should be your go-to way of fixing the issue of missing certificates) and want to use `gocertifi` instead, you can provide pre-loaded cert files as one of the options to the `sentry.Init` call:
+
+```go
+package main
+
+import (
+    "log"
+
+    "github.com/certifi/gocertifi"
+    "github.com/getsentry/sentry-go"
+)
+
+sentryClientOptions := sentry.ClientOptions{
+    Dsn: "___PUBLIC_DSN___",
+}
+
+rootCAs, err := gocertifi.CACerts()
+if err != nil {
+    log.Println("Couldn't load CA Certificates: %v\n", err)
+} else {
+    sentryClientOptions.CaCerts = rootCAs
+}
+
+sentry.Init(sentryClientOptions)
+```
+
+## Usage
+
+### Capturing Errors
+
+raven-go
+
+```go
+f, err := os.Open("filename.ext")
+if err != nil {
+    raven.CaptureError(err, nil)
+}
+```
+
+sentry-go
+
+```go
+f, err := os.Open("filename.ext")
+if err != nil {
+    sentry.CaptureException(err)
+}
+```
+
+### Capturing Panics
+
+raven-go
+
+```go
+raven.CapturePanic(func() {
+    // do all of the scary things here
+}, nil)
+```
+
+sentry-go
+
+```go
+func() {
+    defer sentry.Recover()
+    // do all of the scary things here
+}()
+```
+
+### Capturing Messages
+
+raven-go
+
+```go
+raven.CaptureMessage("Something bad happened and I would like to know about that")
+```
+
+sentry-go
+
+```go
+sentry.CaptureMessage("Something bad happened and I would like to know about that")
+```
+
+### Capturing Events
+
+raven-go
+
+```go
+packet := &raven.Packet{
+    Message: "Hand-crafted event",
+    Extra: &raven.Extra{
+        "runtime.Version": runtime.Version(),
+        "runtime.NumCPU": runtime.NumCPU(),
+    },
+}
+raven.Capture(packet)
+```
+
+sentry-go
+
+```go
+event := &sentry.NewEvent()
+event.Message = "Hand-crafted event"
+event.Extra["runtime.Version"] = runtime.Version()
+event.Extra["runtime.NumCPU"] = runtime.NumCPU()
+
+sentry.CaptureEvent(event)
+```
+
+### Additional Data
+
+See Context section.
+
+### Event Sampling
+
+raven-go
+
+```go
+raven.SetSampleRate(0.25)
+```
+
+sentry-go
+
+```go
+sentry.Init(sentry.ClientOptions{
+    SampleRate: 0.25,
+})
+```
+
+### Awaiting the response (not recommended)
+
+```go
+raven.CaptureMessageAndWait("Something bad happened and I would like to know about that")
+```
+
+sentry-go
+
+```go
+sentry.CaptureMessage("Something bad happened and I would like to know about that")
+
+if sentry.Flush(time.Second * 2) {
+    // event delivered
+} else {
+    // timeout reached
+}

+intended to replace the `raven-go` package.
+
+> Looking for the old `raven-go` SDK documentation? See the Legacy client section [here](https://docs.sentry.io/clients/go/).
+> If you want to start using sentry-go instead, check out the [migration guide](https://docs.sentry.io/platforms/go/migration/).
+
+## Requirements
+
+The only requirement is a Go compiler.
+
+We verify this package against the 3 most recent releases of Go. Those are the
+supported versions. The exact versions are defined in
+[`.travis.yml`](.travis.yml).
+
+In addition, we run tests against the current master branch of the Go toolchain,
+though support for this configuration is best-effort.
+
+## Installation
+
+`sentry-go` can be installed like any other Go library through `go get`:
+
+```console
+$ go get github.com/getsentry/sentry-go
+```
+
+Or, if you are already using
+[Go Modules](https://github.com/golang/go/wiki/Modules), you may specify a
+version number as well:
+
+```console
+$ go get github.com/getsentry/sentry-go@latest
+```
+
+Check out the [list of released versions](https://pkg.go.dev/github.com/getsentry/sentry-go?tab=versions). 
+
+## Configuration
+
+To use `sentry-go`, you’ll need to import the `sentry-go` package and initialize
+it with your DSN and other [options](https://godoc.org/github.com/getsentry/sentry-go#ClientOptions).
+
+If not specified in the SDK initialization, the
+[DSN](https://docs.sentry.io/error-reporting/configuration/?platform=go#dsn),
+[Release](https://docs.sentry.io/workflow/releases/?platform=go) and
+[Environment](https://docs.sentry.io/enriching-error-data/environments/?platform=go)
+are read from the environment variables `SENTRY_DSN`, `SENTRY_RELEASE` and
+`SENTRY_ENVIRONMENT`, respectively.
+
+More on this in the [Configuration](https://docs.sentry.io/platforms/go/config/)
+section of the official Sentry documentation.
+
+## Usage
+
+The SDK must be initialized with a call to `sentry.Init`. The default transport
+is asynchronous and thus most programs should call `sentry.Flush` to wait until
+buffered events are sent to Sentry right before the program terminates.
+
+Typically, `sentry.Init` is called in the beginning of `func main` and
+`sentry.Flush` is [deferred](https://golang.org/ref/spec#Defer_statements) right
+after.
+
+> Note that if the program terminates with a call to
+> [`os.Exit`](https://golang.org/pkg/os/#Exit), either directly or indirectly
+> via another function like `log.Fatal`, deferred functions are not run.
+>
+> In that case, and if it is important for you to report outstanding events
+> before terminating the program, arrange for `sentry.Flush` to be called before
+> the program terminates.
+
+Example:
+
+```go
+// This is an example program that makes an HTTP request and prints response
+// headers. Whenever a request fails, the error is reported to Sentry.
+//
+// Try it by running:
+//
+// 	go run main.go
+// 	go run main.go https://sentry.io
+// 	go run main.go bad-url
+//
+// To actually report events to Sentry, set the DSN either by editing the
+// appropriate line below or setting the environment variable SENTRY_DSN to
+// match the DSN of your Sentry project.
+package main
+
+import (
+	"fmt"
+	"log"
+	"net/http"
+	"os"
+	"time"
+
+	"github.com/getsentry/sentry-go"
+)
+
+func main() {
+	if len(os.Args) < 2 {
+		log.Fatalf("usage: %s URL", os.Args[0])
+	}
+
+	err := sentry.Init(sentry.ClientOptions{
+		// Either set your DSN here or set the SENTRY_DSN environment variable.
+		Dsn: "",
+		// Enable printing of SDK debug messages.
+		// Useful when getting started or trying to figure something out.
+		Debug: true,
+	})
+	if err != nil {
+		log.Fatalf("sentry.Init: %s", err)
+	}
+	// Flush buffered events before the program terminates.
+	// Set the timeout to the maximum duration the program can afford to wait.
+	defer sentry.Flush(2 * time.Second)
+
+	resp, err := http.Get(os.Args[1])
+	if err != nil {
+		sentry.CaptureException(err)
+		log.Printf("reported to Sentry: %s", err)
+		return
+	}
+	defer resp.Body.Close()
+
+	for header, values := range resp.Header {
+		for _, value := range values {
+			fmt.Printf("%s=%s\n", header, value)
+		}
+	}
+}
+```
+
+For your convenience, this example is available at
+[`example/basic/main.go`](example/basic/main.go).
+There are also more examples in the
+[example](example) directory.

+# Official Sentry Echo Handler for Sentry-go SDK
+
+**Godoc:** https://godoc.org/github.com/getsentry/sentry-go/echo
+
+**Example:** https://github.com/getsentry/sentry-go/tree/master/example/echo
+
+## Installation
+
+```sh
+go get github.com/getsentry/sentry-go/echo
+```
+
+```go
+import (
+    "fmt"
+    "net/http"
+
+    "github.com/getsentry/sentry-go"
+    sentryecho "github.com/getsentry/sentry-go/echo"
+    "github.com/labstack/echo/v4"
+	"github.com/labstack/echo/v4/middleware"
+)
+
+// To initialize Sentry's handler, you need to initialize Sentry itself beforehand
+if err := sentry.Init(sentry.ClientOptions{
+    Dsn: "your-public-dsn",
+}); err != nil {
+    fmt.Printf("Sentry initialization failed: %v\n", err)
+}
+
+// Then create your app
+app := echo.New()
+
+app.Use(middleware.Logger())
+app.Use(middleware.Recover())
+
+// Once it's done, you can attach the handler as one of your middleware
+app.Use(sentryecho.New(sentryecho.Options{}))
+
+// Set up routes
+app.GET("/", func(ctx echo.Context) error {
+    return ctx.String(http.StatusOK, "Hello, World!")
+})
+
+// And run it
+app.Logger.Fatal(app.Start(":3000"))
+```
+
+## Configuration
+
+`sentryecho` accepts a struct of `Options` that allows you to configure how the handler will behave.
+
+Currently it respects 3 options:
+
+```go
+// Repanic configures whether Sentry should repanic after recovery, in most cases it should be set to true,
+// as echo includes its own Recover middleware that handles http responses.
+Repanic bool
+// WaitForDelivery configures whether you want to block the request before moving forward with the response.
+// Because Echo's `Recover` handler doesn't restart the application,
+// it's safe to either skip this option or set it to `false`.
+WaitForDelivery bool
+// Timeout for the event delivery requests.
+Timeout time.Duration
+```
+
+## Usage
+
+`sentryecho` attaches an instance of `*sentry.Hub` (https://godoc.org/github.com/getsentry/sentry-go#Hub) to the `echo.Context`, which makes it available throughout the rest of the request's lifetime.
+You can access it by using the `sentryecho.GetHubFromContext()` method on the context itself in any of your proceeding middleware and routes.
+And it should be used instead of the global `sentry.CaptureMessage`, `sentry.CaptureException`, or any other calls, as it keeps the separation of data between the requests.
+
+**Keep in mind that `*sentry.Hub` won't be available in middleware attached before to `sentryecho`!**
+
+```go
+app := echo.New()
+
+app.Use(middleware.Logger())
+app.Use(middleware.Recover())
+
+app.Use(sentryecho.New(sentryecho.Options{
+	Repanic: true,
+}))
+
+app.Use(func(next echo.HandlerFunc) echo.HandlerFunc {
+	return func(ctx echo.Context) error {
+		if hub := sentryecho.GetHubFromContext(ctx); hub != nil {
+			hub.Scope().SetTag("someRandomTag", "maybeYouNeedIt")
+		}
+		return next(ctx)
+	}
+})
+
+app.GET("/", func(ctx echo.Context) error {
+	if hub := sentryecho.GetHubFromContext(ctx); hub != nil {
+		hub.WithScope(func(scope *sentry.Scope) {
+			scope.SetExtra("unwantedQuery", "someQueryDataMaybe")
+			hub.CaptureMessage("User provided unwanted query string, but we recovered just fine")
+		})
+	}
+	return ctx.String(http.StatusOK, "Hello, World!")
+})
+
+app.GET("/foo", func(ctx echo.Context) error {
+	// sentryecho handler will catch it just fine. Also, because we attached "someRandomTag"
+	// in the middleware before, it will be sent through as well
+	panic("y tho")
+})
+
+app.Logger.Fatal(app.Start(":3000"))
+```
+
+### Accessing Request in `BeforeSend` callback
+
+```go
+sentry.Init(sentry.ClientOptions{
+    Dsn: "your-public-dsn",
+    BeforeSend: func(event *sentry.Event, hint *sentry.EventHint) *sentry.Event {
+        if hint.Context != nil {
+            if req, ok := hint.Context.Value(sentry.RequestContextKey).(*http.Request); ok {
+                // You have access to the original Request here
+            }
+        }
+
+        return event
+    },
+})
+```
