+
+As of May 4, 2017, there have been no new features or major notable changes since 3.6.0.
+
+A few typos were fixed, a few Linux kernel configuration flags were added, and a few error messages were enhanced.

+
+- [#895][895] Added a Dockerfile to simplify testing setup and allow testing on OSX
+- [#897][897] Fixed some incorrect AArch64 syscals
+- [#893][893] Added the `pwnlib.config` module
+    + Configuration options can now be set in `~/.pwn.conf`
+    + This replaces the old, **undocumented** mechanism for changing logging colors.  Only @br0ns and @ebeip90 were likely using this.
+    + More information is available in the documentation [here](http://docs.pwntools.com/en/dev/config.html).

+- [#904][904] Enhancements to the accuracy of the `pwn checksec` command.

+
+## 3.5.0
+
+- [b584ca3][b584ca3] Fixed an issue running `setup.py` on ARM
+- [#822][822] Enabled relative leaks with `MemLeak`
+    + This should be useful for e.g. heap-relative leaks
+- [#832][832] Changed all internal imports to use absolute imports (no functional changes)
+- [a12d0b6][a12d0b6] Move `STDOUT`, `PIPE`, `PTY` constants to globals
+    + `process(..., stdin=process.PTY)` --> `process(..., stdin=PTY)`
+- [#828][828] Use `PR_SET_PTRACER` for all `process()` and `ssh.process()` instances
+    + This simplifies debugging on systems with YAMA ptrace enabled
+- Various documentation enhancements
+    + In particular, the [gdb][gdb], [elf][elf], and [ssh][ssh] docs are much better
+- [#833][833] Performance enhancements for `adb` module
+- [d0267f3][d0267f3] `packing.fit()` now treats large offsets as cyclic patterns (e.g. `0x61616161` behaves the same as `"aaaa"`)
+- [#835][835] Added `ssh.checksec`
+    + Reports the kernel version and other relevant information on connection
+- [#857][857] Slightly shortened `execve` shellcode
+- [300f8e0][300f8e0] Slightly speed up processing of large ELF files
+- [#861][861] Adds support for extracting `IKCONFIG` configs from Linux kernel images, and extends `checksec` to report on any insecure configurations discovered
+- [#871][871] Moves all of the basic syscall templates to `shellcraft/common` and exposes them via symlinks.  Closed [#685][685]
+    + Should not have any visible effects from any documented APIs
+    + `shellcraft.arch.os.syscall_function()` still works the same
+    + We now have the ability to differentiate between the `connect` syscall, and a TCP `connect` helper
+- [#887][887] `sh_string` now returns a quoted empty string `''` rather than just an empty string
+- [#839][839] Exposes a huge amount of functionality via corefiles which was not previously availble.  See the [docs][corefile_docs] for examples.
+    + `process().corefile` will automatically instantiate a Corefile for the process
+    + QEMU-emulated processes are supported
+    + Native processes are supported, including extraction of coredumps from `apport` crash logs
+    + Native processes can be dumped *while running*, in a manner similar to `GDB`'s `gcore` script
+- [#875][857] Added [documentation][aarch64] (and tests) for AArch64 shellcode
+- [#882][882] The `ROP` class now respects `context.bytes` instead of using the hard-coded value of `4` (fixed [#879][879])
+- [#869][869] Added several fields to the `process` class (`uid`, `gid`, `suid`, `sgid`) which are recorded at execution time, based on the file permissions
+- [#868][868] Changed the way that `ssh.process()` works internally, and it now returns a more specialized class, `ssh_process`.
+    + Added `ssh_process.corefile` for fetching remote corefiles
+    + Added `ssh_process.ELF` for getting an ELF of the remote executable
+    + The `uid`, `gid`, and `suid`, and `sgid` which are recorded at execution time, based on the file permissions
+- [#865][865] Fixes `ELF.read` to support contiguous memory reads across non-contiguous file-backed segments
+- [#862][862] Adds a `symlink=` argument to `ssh.set_working_directory`, which will automatically symlink all of the files in the "old" working directory into the "new" working directory

+## Testing in Docker
+
+A `Dockerfile` has been provided which has a clean testing environment with Ubuntu Xenial.  It is very similar to the online Travis CI testing environment, but uses a more modern version of Ubuntu.
+
+See `travis/docker/README.md` for more information.
+
 ## New Tests

 To add a new test to an existing module, just add an inline doctest.  If the test needs access to an external module, add the import statement to the `testsetup` block in the corresponding file in `docs/source/<module>.rst`.

-
-        Note:
-            In recent releases of Android (e.g. 7.0), the domain that

-            the shell user does.
-
-            Because of this, while the shell user can get listings of
-            e.g. the root directory ('/'), adbd cannot.
-
-            The SYNC APIs are executed within the adbd context, not the
-            shell user context.
-
-            This issue is not a problem if the phone is rooted via
-            'adb root', since adbd then runs in the ``su`` domain.

+Pwntools exposes several magic command-line arguments and environment
