 things like file and directory names, so please either redact it before
 uploading it somewhere or post only the parts that are really relevant.
 
+If restic gets stuck, please also include a stacktrace in the description.
+On non-Windows systems, you can send a SIGQUIT signal to restic or press
+`Ctrl-\` to achieve the same result. This causes restic to print a stacktrace
+and then exit immediatelly. This will not damage your repository, however,
+it might be necessary to manually clean up stale lock files using
+`restic unlock`.
+
+On Windows, please set the environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT`
+to `true` and press `Ctrl-C` to create a stacktrace.

+If you think restic uses too much memory or a too large cache directory, then

 Development Environment
 =======================
@@ -76,12 +89,42 @@ Then use the `go` tool to build restic:
 
     $ go build ./cmd/restic

-    restic 0.10.0-dev (compiled manually) compiled with go1.15.2 on linux/amd64

+    $ go build -tags debug ./cmd/restic
 
 You can run all tests with the following command:
 
     $ go test ./...
 
+
+Performance and Memory Usage Issues
+===================================
+
+Debug builds of restic support the `--block-profile`, `--cpu-profile`,
+`--mem-profile`, and `--trace-profile` options which collect performance data
+that later on can be analyzed using the go tools:
+
+    $ restic --cpu-profile . [...]
+    $ go tool pprof -http localhost:12345 cpu.pprof
+
+To analyze a trace profile use `go tool trace -http=localhost:12345 trace.out`.
+
+As the memory usage of restic changes over time, it may be useful to capture a
+snapshot of the current heap. This is possible using then `--listen-profile`
+option. Then while restic runs you can query and afterwards analyze the heap statistics.
+
+    $ restic --listen-profile localhost:12345 [...]
+    $ curl http://localhost:12345/debug/pprof/heap -o heap.pprof
+    $ go tool pprof -http localhost:12345 heap.pprof
+
+Further useful tools are setting the environment variable `GODEBUG=gctrace=1`,
+which provides information about garbage collector runs. For a graphical variant
+combine this with gcvis.

+Enhancement: Support B2 API keys restricted to hiding but not deleting files
+
+When the B2 backend does not have the necessary permissions to permanently
+delete files, it now automatically falls back to hiding files. This allows
+using restic with an application key which is not allowed to delete files.
+This can prevent an attacker from deleting backups with such an API key.
+
+To use this feature create an application key without the `deleteFiles`
+capability. It is recommended to restrict the key to just one bucket.
+For example using the `b2` command line tool:
+
+`b2 create-key --bucket <bucketName> <keyName> listBuckets,readFiles,writeFiles,listFiles`
+
+Alternatively, you can use the S3 backend to access B2, as described
+in the documentation. In this mode, files are also only hidden instead
+of being deleted permanently.

+Enhancement: Stricter repository lock handling
+
+Previously, restic commands kept running even if they failed to refresh their
+locks in time. This could be a problem e.g. in case the client system running
+a backup entered the standby power mode while the backup was still in progress
+(which would prevent the client from refreshing its lock), and after a short
+delay another host successfully runs `unlock` and `prune` on the repository,
+which would remove all data added by the in-progress backup. If the backup
+client later continues its backup, even though its lock had expired in the
+meantime, this would lead to an incomplete snapshot.
+
+To address this, lock handling is now much stricter. Commands requiring a lock
+are canceled if the lock is not refreshed successfully in time. In addition,
+if a lock file is not readable restic will not allow starting a command. It may
+be necessary to remove invalid lock files manually or use `unlock --remove-all`.
+Please make sure that no other restic processes are running concurrently before
+doing this, however.

+With restic 0.15.0 the checks for stale locks became much stricter than before.
+In particular, empty or unreadable locks were no longer silently ignored. This

+Bugfix: Minimize risk of spurious filesystem loops with `mount`
+
+When a backup contains a directory that has the same name as its parent, say
+`a/b/b`, and the GNU `find` command was run on this backup in a restic mount,
+`find` would refuse to traverse the lowest `b` directory, instead printing
+`File system loop detected`. This was due to the way the restic mount command
+generates inode numbers for directories in the mount point.
+
+The rule for generating these inode numbers was changed in 0.15.0. It has

+but the probability of this behavior occurring is now extremely small.
+
+When it does occur, the mount point is not broken, and scripts that traverse

+Bugfix: Make `key list` command honor `--no-lock`
+
+The `key list` command now supports the `--no-lock` options. This allows
+determining which keys a repo can be accessed by without the need for having
+write access (e.g., read-only sftp access, filesystem snapshot).

+Bugfix: Update zstd library to fix possible data corruption at max. compression
+
+In restic 0.16.0, backups where the compression level was set to `max` (using
+`--compression max`) could in rare and very specific circumstances result in
+data corruption due to a bug in the library used for compressing data.
+
+Restic now uses the latest version of the library used to compress data, which
+includes a fix for this issue. Please note that the `auto` compression level
+(which restic uses by default) was never affected, and even if you used `max`
+compression, chances of being affected by this issue were very small.
+
+To check a repository for any corruption, run `restic check --read-data`. This
+will download and verify the whole repository and can be used at any time to
+completely verify the integrity of a repository. If the `check` command detects
+anomalies, follow the suggested steps.
+
+To simplify any needed repository repair and minimize data loss, there is also
+a new and experimental `repair packs` command that salvages all valid data from
+the affected pack files (see `restic help repair packs` for more information).

+Enhancement: Allow setting REST password and username via environment variables
+
+Previously, it was only possible to specify the REST-server username and
+password in the repository URL, or by using the `--repository-file` option.
+This meant it was not possible to use authentication in contexts where the
+repository URL is stored in publicly accessible way.
+
+Restic now allows setting the username and password using the
+`RESTIC_REST_USERNAME` and `RESTIC_REST_PASSWORD` variables.

+Enhancement: Add config option to set SFTP command arguments
+
+When using the `sftp` backend, scenarios where a custom identity file was
+needed for the SSH connection, required the full command to be specified:
+`-o sftp.command='ssh user@host:port -i /ssh/my_private_key -s sftp'`
+
+Now, the `-o sftp.args=...` option can be passed to restic to specify
+custom arguments for the SSH command executed by the SFTP backend.
+This simplifies the above example to `-o sftp.args='-i /ssh/my_private_key'`.
