- Add `os/strftime` for date formatting.
- Fix `ev/select` on threaded channels sometimes live-locking.
- Support the `NO_COLOR` environment variable to turn off VT100 color codes in repl (and in scripts).
See http://no-color.org/
- Disallow using `(splice x)` in contexts where it doesn't make sense rather than silently coercing to `x`.

allows easier manipulation of FFI memory, memory mapped files, and buffer memory shared between threads.
- Calling `ev/cancel` on a fiber waiting on `ev/gather` will correctly
cancel the child fibers.
- Add `(sandbox ...)` function to core for permission based security. Also add `janet_sandbox` to C API.
The sandbox allows limiting access to the file system, network, ffi, and OS resources at runtime.
- Add `(.locals)` function to debugger to see currently bound local symbols.
- Track symbol -> slot mapping so debugger can get symbolic information. This exposes local bindings
in `debug/stack` and `disasm`.
- Add `os/compiler` to detect what host compiler was used to compile the interpreter
- Add support for mingw and cygwin builds (mingw support also added in jpm).
## 1.26.0 - 2023-01-07
- Add `ffi/malloc` and `ffi/free`. Useful as tools of last resort.
- Add `ffi/jitfn` to allow calling function pointers generated at runtime from machine code.
Bring your own assembler, though.
- Channels can now be marshalled. Pending state is not saved, only items in the channel.
- Use the new `.length` function pointer on abstract types for lengths. Adding
a `length` method will still work as well.
- Support byte views on abstract types with the `.bytes` function pointer.
- Add the `u` format specifier to printf family functions.
- Allow printing 64 integer types in `printf` and `string/format` family functions.
- Allow importing modules from custom directories more easily with the `@` prefix
to module paths. For example, if there is a dynamic binding :custom-modules that
is a file system path to a directory of modules, import from that directory with
`(import @custom-modules/mymod)`.
- Fix error message bug in FFI library.
## 1.25.1 - 2022-10-29

this change, supervisor messages over threaded channels would be from ambiguous threads/fibers.
## 1.23.0 - 2022-06-20
- Add experimental `ffi/` module for interfacing with dynamic libraries and raw function pointers. Only available
on 64 bit linux, mac, and bsd systems.
- Allow using `&named` in function prototypes for named arguments. This is a more ergonomic
variant of `&keys` that isn't as redundant, more self documenting, and allows extension to
things like default arguments.
- Add `delay` macro for lazy evaluate-and-save thunks.
- Remove pthread.h from janet.h for easier includes.
- Add `debugger` - an easy to use debugger function that just takes a fiber.

easier to build without `jpm`.
## 1.21.2 - 2022-04-01
- C functions `janet_dobytes` and `janet_dostring` will now enter the event loop if it is enabled.
- Fix hashing regression - hash of negative 0 must be the same as positive 0 since they are equal.
- The `flycheck` function no longer pollutes the module/cache
- Fix quasiquote bug in compiler
- Disallow use of `cancel` and `resume` on fibers scheduled or created with `ev/go`, as well as the root
fiber.
## 1.20.0 - 2022-1-27
- Add `:missing-symbol` hook to `compile` that will act as a catch-all macro for undefined symbols.

saving and restoring the entire VM state.
## 1.16.1 - 2021-06-09
- Add `maclintf` - a utility for adding linting messages when inside macros.
- Print source code of offending line on compiler warnings and errors.
- Fix some issues with linting and re-add missing `make docs`.
- Allow controlling linting with dynamic bindings `:lint-warn`, `:lint-error`, and `:lint-levels`.
- Add `-w` and `-x` command line flags to the `janet` binary to set linting thresholds.
linting thresholds are as follows:
- :none - will never be trigger.
- :relaxed - will only trigger on `:relaxed` lints.
- :normal - will trigger on `:relaxed` and `:normal` lints.
- :strict - will trigger on `:strict`, `:normal`, and `:relaxed` lints. This will catch the most issues
but can be distracting.
## 1.16.0 - 2021-05-30
- Add color documentation to the `doc` macro - enable/disable with `(dyn :doc-color)`.
- Remove simpler HTML docs from distribution - use website or built-in documentation instead.
- Add compiler warnings and deprecation levels.
- Add `as-macro` to make using macros within quasiquote easier to do hygienically.
- Expose `JANET_OUT_OF_MEMORY` as part of the Janet API.

that can be installed via `jpm`.
- Add `from-pairs` to core.
- Add `JPM_OS_WHICH` environment variable to jpm to allow changing auto-detection behavior.
- The flychecker will consider any top-level calls of functions that start with `define-` to
be safe to execute and execute them. This allows certain patterns (like spork/path) to be
better processed by the flychecker.
## 1.15.5 - 2021-04-25
- Add `declare-headers` to jpm.
- Fix error using unix pipes on BSDs.

are considered to have width 1 (instead of 8).
## 1.14.2 - 2021-01-23
- Allow `JANET_PROFILE` env variable to load a profile before loading the repl.
- Update `tracev` macro to allow `def` and `var` inside to work as expected.

`default-peg-grammar` directly from the root environment.
- Add `ev/thread` for combining threading with the event loop.
- Add `ev/do-thread` to make `ev/thread` easier to use.
- Automatically set supervisor channel in `net/accept-loop` and `net/server` correctly.
## 1.14.1 - 2021-01-18
- Add `doc-of` for reverse documentation lookup.
- Add `ev/give-supervsior` to send a message to the supervising channel.
- Add `ev/gather` and `chan` argument to `ev/go`. This new argument allows "supervisor channels"
for fibers to enable structured concurrency.
- Make `-k` flag work on stdin if no files are given.
- Add `flycheck` function to core.
- Make `backmatch` and `backref` more expressive in pegs.
- Fix buggy `string/split`.
- Add `fiber/last-value` to get the value that was last yielded, errored, or signaled
by a fiber.
- Remove `:generate` verb from `loop` macros. Instead, use the `:in` verb
which will now work on fibers as well as other data structures.
- Define `next`, `get`, and `in` for fibers. This lets
`each`, `map`, and similar iteration macros can now iterate over fibers.
- Remove macro `eachy`, which can be replaced by `each`.
- Add `dflt` argument to find-index.
- Deprecate `file/popen` in favor of `os/spawn`.
- Add `:all` keyword to `ev/read` and `net/read` to make them more like `file/read`. However, we
do not provide any `:line` option as that requires buffering.
- Change repl behavior to make Ctrl-C raise SIGINT on posix. The old behavior for Ctrl-C,
to clear the current line buffer, has been moved to Ctrl-Q.
- Importing modules that start with `/` is now the only way to import from project root.
Before, this would import from / on disk. Previous imports that did not start with `.` or `/`
are now unambiguously importing from the syspath, instead of checking both the syspath and
the project root. This is backwards incompatible and dependencies should be updated for this.
- Change hash function for numbers.
- Improve error handling of `dofile`.
- Bug fixes in networking and subprocess code.
- Use markdown formatting in more places for docstrings.
## 1.13.1 - 2020-12-13
- Pretty printing a table with a prototype will look for `:_name` instead of `:name`
in the prototype table to tag the output.
- `match` macro implementation changed to be tail recursive.
- Adds a :preload loader which allows one to manually put things into `module/cache`.
- Add `buffer/push` function.
- Backtick delimited strings and buffers are now reindented based on the column of the
opening delimiter. Whitespace in columns to the left of the starting column is ignored unless
there are non-space/non-newline characters in that region, in which case the old behavior is preserved.
- Argument to `(error)` combinator in PEGs is now optional.
- Add `(line)` and `(column)` combinators to PEGs to capture source line and column.
This should make error reporting a bit easier.
- Add `merge-module` to core.
- During installation and release, merge janetconf.h into janet.h for easier install.
- Add `upscope` special form.
- `os/execute` and `os/spawn` can take streams for redirecting IO.
- Add `:parser` and `:read` parameters to `run-context`.
- Add `os/open` if ev is enabled.
- Add `os/pipe` if ev is enabled.
- Add `janet_thread_current(void)` to C API
- Add integer parsing forms to pegs. This makes parsing many binary protocols easier.
- Lots of updates to networking code - now can use epoll (or poll) on linux and IOCP on windows.
- Add `ev/` module. This exposes a fiber scheduler, queues, timeouts, and other functionality to users
for single threaded cooperative scheduling and asynchronous IO.
- Add `net/accept-loop` and `net/listen`. These functions break down `net/server` into it's essential parts
and are more flexible. They also allow further improvements to these utility functions.
- Various small bug fixes.
## 1.12.2 - 2020-09-20
- Add janet\_try and janet\_restore to C API.
- Fix `os/execute` regression on windows.

- Add `os/spawn` to get a core/process back instead of an exit code as in `os/execute`.
When called like this, `os/execute` returns immediately.
- Add `:x` flag to os/execute to raise error when exit code is non-zero.
- Don't run `main` when flychecking.
- Add `:n` flag to `file/open` to raise an error if file cannot be opened.
- Fix import macro to not try and coerce everything to a string.
- Allow passing a second argument to `disasm`.

- Allow multi-line paste into built in repl.
- Add `(curenv)`.
- Change `net/read`, `net/chunk`, and `net/write` to raise errors in the case of failures.

to raise errors or other signals.
- Update meson build script to fix bug on Debian's version of meson
- Add `xprint`, `xprin`, `xprintf`, and `xprinf`.
- `net/write` now raises an error message if write fails.

- Remove `file/fileno` and `file/fdopen`.
- Remove `==`, `not==`, `order<`, `order>`, `order<=`, and `order>=`. Instead, use the normal
comparison and equality functions.
- Let abstract types define a hash function and comparison/equality semantics. This lets
abstract types much better represent value types. This adds more fields to abstract types, which
will generate warnings when compiled against other versions.
- Remove Emscripten build. Instead, use the amalgamated source code with a custom toolchain.
- Update documentation.
- Add `var-`
- Add `module/add-paths`
- Add `file/temp`
- Add `mod` function to core.
- Small bug fixes
- Allow signaling from C functions (yielding) via janet\_signalv. This
makes it easy to write C functions that work with event loops, such as
in libuv or embedded in a game.
- Add '%j' formatting option to the format family of functions.
- Add `defer`
- Add `assert`
- Add `when-with`
- Add `if-with`
- Add completion to the default repl based on currently defined bindings. Also generally improve
the repl keybindings.
- Add `eachk`
- Add `eachp`
- Improve functionality of the `next` function. `next` now works on many different
types, not just tables and structs. This allows for more generic data processing.
- Fix thread module issue where sometimes decoding a message failed.
- Fix segfault regression when macros are called with bad arity.
## 1.6.0 - 2019-12-22
- Add `thread/` module to the core.
- Allow seeding RNGs with any sequence of bytes. This provides
a wider key space for the RNG. Exposed in C as `janet_rng_longseed`.
- Fix issue in `resume` and similar functions that could cause breakpoints to be skipped.
- Add a number of new math functions.
- Improve debugger experience and capabilities. See examples/debugger.janet
for what an interactive debugger could look like.
- Add `debug/step` (janet\_step in the C API) for single stepping Janet bytecode.
- The built in repl now can enter the debugger on any signal (errors, yields,
user signals, and debug signals). To enable this, type (setdyn :debug true)
in the repl environment.
- When exiting the debugger, the fiber being debugged is resumed with the exit value
of the debug session (the value returned by `(quit return-value)`, or nil if user typed Ctrl-D).
- `(quit)` can take an optional argument that is the return value. If a module
contains `(quit some-value)`, the value of that module returned to `(require "somemod")`
is the return value. This lets module writers completely customize a module without writing
a loader.
- Add nested quasiquotation.
- Add `os/cryptorand`
- Add `prinf` and `eprinf` to be have like `printf` and `eprintf`. The latter two functions
now including a trailing newline, like the other print functions.

- Add `protect` macro.
- Add `root-env` to get the root environment table.
- Change marshalling protocol with regard to abstract types.
- Add `show-paths` to `jpm`.
- Add several default patterns, like `:d` and `:s+`, to PEGs.
- Update `jpm` path settings to make using `jpm` easier on non-global module trees.
- Numerous small bug fixes and usability improvements.
### 1.5.1 - 2019-11-16

- Fix `update` return value.
## 1.5.0 - 2019-11-10
- `os/date` now defaults to UTC.
- Add `--test` flag to jpm to test libraries on installation.
- Add `math/rng`, `math/rng-int`, and `math/rng-uniform`.
- Add `in` function to index in a stricter manner. Conversely, `get` will
now not throw errors on bad keys.
- Indexed types and byte sequences will now error when indexed out of range or
with bad keys.
- Add rng functions to Janet. This also replaces the RNG behind `math/random`
and `math/seedrandom` with a consistent, platform independent RNG.
- Add `with-vars` macro.
- Add the `quickbin` command to jpm.
- Create shell.c when making the amalgamated source. This can be compiled with
janet.c to make the janet interpreter.
- Add `cli-main` function to the core, which invokes Janet's CLI interface.
This basically moves what was init.janet into boot.janet.
- Improve flychecking, and fix flychecking bugs introduced in 1.4.0.
- Add `prin`, `eprint`, `eprintf` and `eprin` functions. The
functions prefix with e print to `(dyn :err stderr)`
- Print family of functions can now also print to buffers
(before, they could only print to files.) Output can also
be completely disabled with `(setdyn :out false)`.
- `printf` is now a c function for optimizations in the case
of printing to buffers.
## 1.4.0 - 2019-10-14
- Add `quit` function to exit from a repl, but not always exit the entire
application.
- Add `update-pkgs` to jpm.
- Integrate jpm with https://github.com/janet-lang/pkgs.git. jpm can now
install packages based on their short names in the package listing, which
can be customized via an env variable.
- Add `varfn` macro
- Add compile time arity checking when function in function call is known.
- Added `slice` to the core library.
- The `*/slice` family of functions now can take nil as start or end to get
the same behavior as the defaults (0 and -1) for those parameters.
- `string/` functions that take a pattern to search for will throw an error
when receiving the empty string.
- Replace (start:end) style stacktrace source position information with
line, column. This should be more readable for humans. Also, range information
can be recovered by re-parsing source.
## 1.3.1 - 2019-09-21
- Fix some linking issues when creating executables with native dependencies.
- jpm now runs each test script in a new interpreter.

- Add `mean` to core.
- Abstract types that implement the `:+`, `:-`, `:*`, `:/`, `:>`, `:==`, `:<`,
`:<=`, and `:>=` methods will work with the corresponding built-in
arithmetic functions. This means built-in integer types can now be used as
normal number values in many contexts.
- Allow (length x) on typed arrays an other abstract types that implement
the :length method.
## 1.3.0 - 2019-09-05
- Add `get-in`, `put-in`, `update-in`, and `freeze` to core.
- Add `jpm run rule` and `jpm rules` to jpm to improve utility and discoverability of jpm.
- Remove `cook` module and move `path` module to https://github.com/janet-lang/path.git.
The functionality in `cook` is now bundled directly in the `jpm` script.
- Add `buffer/format` and `string/format` format flags `Q` and `q` to print colored and
non-colored single-line values, similar to `P` and `p`.
- Change default repl to print long sequences on one line and color stacktraces if color is enabled.
- Add `backmatch` pattern for PEGs.
- jpm detects if not in a Developer Command prompt on windows for a better error message.
- jpm install git submodules in dependencies
- Change default fiber stack limit to the maximum value of a 32 bit signed integer.
- Some bug fixes with `jpm`

## 1.2.0 - 2019-08-08
- Add `take` and `drop` functions that are easier to use compared to the
existing slice functions.
- Add optional default value to `get`.
- Add function literal short-hand via `|` reader macro, which maps to the
`short-fn` macro.
- Add `int?` and `nat?` functions to the core.
- Add `(dyn :executable)` at top level to get what used to be
`(process/args 0)`.
- Add `:linux` to platforms returned by `(os/which)`.
- Update jpm to build standalone executables. Use `declare-executable` for this.
- Add `use` macro.
- Remove `process/args` in favor of `(dyn :args)`.
- Fix bug with Nanbox implementation allowing users to created
custom values of any type with typed array and marshal modules, which
was unsafe.
- Add `janet_wrap_number_safe` to API, for converting numbers to Janets
where the number could be any 64 bit, user provided bit pattern. Certain
NaN values (which a machine will never generate as a result of a floating
point operation) are guarded against and converted to a default NaN value.
## 1.1.0 - 2019-07-08
- Change semantics of `-l` flag to be import rather than dofile.
- Fix compiler regression in top level defs with destructuring.
- Add `table/clone`.
- Improve `jpm` tool with git and dependency capabilities, as well as better
module uninstalls.
## 1.0.0 - 2019-07-01
- Add `with` macro for resource handling.
- Add `propagate` function so we can "rethrow" signals after they are
intercepted. This makes signals even more flexible.
- Add `JANET_NO_DOCSTRINGS` and `JANET_NO_SOURCEMAPS` defines in janetconf.h
for shrinking binary size.
This seems to save about 50kB in most builds, so it's not usually worth it.
- Update module system to allow relative imports. The `:cur:` pattern
in `module/expand-path` will expand to the directory part of the current file, or
whatever the value of `(dyn :current-file)` is. The `:dir:` pattern gets
the directory part of the input path name.
- Remove `:native:` pattern in `module/paths`.
- Add `module/expand-path`
- Remove `module/*syspath*` and `module/*headerpath*` in favor of dynamic
bindings `:syspath` and `:headerpath`.

- Add optional `env` argument to `all-bindings` and `all-dynamics`.
- Add scratch memory C API functions for auto-released memory on next gc.
Scratch memory differs from normal GCed memory as it can also be freed normally
for better performance.
- Add API compatibility checking for modules. This will let native modules not load
when the host program is not of a compatible version or configuration.
- Change signature of `os/execute` to be much more flexible.
## 0.6.0 - 2019-05-29
