 # Changelog
 
+## v2.8.1 - 2019-05-20
+
+- Fix error code for the `--help` flag
+  ([#300](https://github.com/go-task/task/issues/300), [#330](https://github.com/go-task/task/pull/330)).
+- Print version to stdout instead of stderr
+  ([#299](https://github.com/go-task/task/issues/299), [#329](https://github.com/go-task/task/pull/329)).
+- Supress `context` errors when using the `--watch` flag
+  ([#313](https://github.com/go-task/task/issues/313), [#317](https://github.com/go-task/task/pull/317)).
+- Support templating on description
+  ([#276](https://github.com/go-task/task/issues/276), [#283](https://github.com/go-task/task/pull/283)).
+
+## v2.8.0 - 2019-12-07
+
+- Add `--parallel` flag (alias `-p`) to run tasks given by the command line in
+  parallel
+  ([#266](https://github.com/go-task/task/pull/266)).
+- Fixed bug where calling the `task` CLI only informing global vars would not
+  execute the `default` task.
+- Add hability to silent all tasks by adding `silent: true` a the root of the
+  Taskfile.
+
 ## v2.7.1 - 2019-11-10
 
 - Fix error being raised when `exit 0` was called

+# The plan9 package provides access to the raw system call
+# interface of the underlying operating system.  Porting Go to
+# a new architecture/operating system combination requires
+# some manual effort, though there are tools that automate
+# much of the process.  The auto-generated files have names
+# beginning with z.
+#
+# This script runs or (given -n) prints suggested commands to generate z files
+# for the current system.  Running those commands is not automatic.
+# This script is documentation more than anything else.
+#
+# * asm_${GOOS}_${GOARCH}.s
+#
+# This hand-written assembly file implements system call dispatch.
+# There are three entry points:
+#
+# 	func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+# 	func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
+# 	func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+#
+# The first and second are the standard ones; they differ only in
+# how many arguments can be passed to the kernel.
+# The third is for low-level use by the ForkExec wrapper;
+# unlike the first two, it does not call into the scheduler to
+# let it know that a system call is running.
+#
+# * syscall_${GOOS}.go
+#
+# This hand-written Go file implements system calls that need
+# special handling and lists "//sys" comments giving prototypes
+# for ones that can be auto-generated.  Mksyscall reads those
+# comments to generate the stubs.
+#
+# * syscall_${GOOS}_${GOARCH}.go
+#
+# Same as syscall_${GOOS}.go except that it contains code specific
+# to ${GOOS} on one particular architecture.
+#
+# * types_${GOOS}.c
+#
+# This hand-written C file includes standard C headers and then
+# creates typedef or enum names beginning with a dollar sign
+# (use of $ in variable names is a gcc extension).  The hardest
+# part about preparing this file is figuring out which headers to
+# include and which symbols need to be #defined to get the
+# actual data structures that pass through to the kernel system calls.
+# Some C libraries present alternate versions for binary compatibility
+# and translate them on the way in and out of system calls, but
+# there is almost always a #define that can get the real ones.
+# See types_darwin.c and types_linux.c for examples.
+#
+# * zerror_${GOOS}_${GOARCH}.go
+#
+# This machine-generated file defines the system's error numbers,
+# error strings, and signal numbers.  The generator is "mkerrors.sh".
+# Usually no arguments are needed, but mkerrors.sh will pass its
+# arguments on to godefs.
