## Unreleased Changes
### Breaking Change

### Fixed
- Fix retrieve-win-deps Windows build script not working correctly
- Fix context switches between addon callbacks not causing Node.js to drain microtasks - ([#177](https://github.com/JCMais/node-libcurl/issues/204))
- Fix some curl_off_t getinfo values corrupting the stack
- `WRITEFUNCTION`, `HEADERFUNCTION` and `READFUNCTION` callbacks now correctly rethrow JS errors thrown inside of them.
  The return value of both callbacks is now also checked to be an integer, any other type will cause an error.
  This is considered a fix because previously the return value was being cast to an integer, which means the method would already fail, as there are remote chances (aka impossible) casting something else to an integer would yield the length of the data passed by libcurl.

### Added
- Added missing [`CURLOPT_SASL_AUTHZID`](https://curl.haxx.se/libcurl/c/CURLOPT_SASL_AUTHZID.html) option - libcurl 7.66.0
- Added missing `CURLE_AUTH_ERROR` error code added with libcurl 7.66.0
- Added missing [`CURLINFO_RETRY_AFTER`](https://curl.haxx.se/libcurl/c/CURLINFO_RETRY_AFTER.html) info field - libcurl 7.66.0
- Added missing `CURL_HTTP_VERSION_3` constant related http version to the `CurlHttpVersion` enum - libcurl 7.66.0
- Added missing [`CURLMOPT_MAX_CONCURRENT_STREAMS`](https://curl.haxx.se/libcurl/c/CURLMOPT_MAX_CONCURRENT_STREAMS.html) option - libcurl 7.67.0
- Added missing `CurlProgressFunc` enum to reflect the new `CURL_PROGRESSFUNC_CONTINUE` constant - libcurl 7.68.0
- Added missing `CurlSslOpt` enum member `NoPartialChain` - libcurl 7.68.0
- Added missing `CURLE_HTTP3` error code - An HTTP/3 layer problem - libcurl 7.68.0
- Added missing `CURLM_WAKEUP_FAILURE` error code - wakeup is unavailable or failed - libcurl 7.68.0
- Added missing `CURLM_BAD_FUNCTION_ARGUMENT` error code - function called with a bad parameter - libcurl 7.69.0
- Added missing `CURLE_QUIC_CONNECT_ERROR` error code - QUIC connection error - libcurl 7.69.0
- Added missing [`CURLOPT_MAIL_RCPT_ALLLOWFAILS`](https://curl.haxx.se/libcurl/c/CURLOPT_MAIL_RCPT_ALLLOWFAILS) option - libcurl 7.69.0

### Changed
- Prebuilt binaries are now compiled with libcurl 7.69.1 and, when possible, latest version of other related dependencies:
  - OpenSSL 1.1.1d
  - nghttp2 1.4.0
  - libssh2 1.9.0
- Added prebuilt binaries for:
  - Electron v8
  - NW.js v0.44, v0.43 and v0.42
- Dropped prebuilt binaries for:
  - Node.js 8
  - Electron v3, v4 and v5
  - NW.js v0.38 and v0.39
- Remove dynamic require ([#204](https://github.com/JCMais/node-libcurl/issues/204))
- The C++ implementation for the previously removed `onData` and `onHeader` Curl/Easy instance fields has been removed - If you were still using those internal fields your code is going to break. Use `WRITEFUNCTION`  and `HEADERFUNCTION` options instead.
## [2.0.3] - 2019-12-11
### Fixed
- Updated return type of DEBUGFUNCTION ([#202](https://github.com/JCMais/node-libcurl/issues/202))
- Fixed issues when building with newer versions of v8 (Node.js >= 13 and Electron >= 7) ([#203](https://github.com/JCMais/node-libcurl/issues/203))

### Added
- Type for `this` added to event listeners callbacks
- Build on Node.js 13 and Electron 7

## [2.0.2] - 2019-09-20
### Added
- Build on Electron v6
### Changed
- Improved build scripts
- bump libssh2 to 1.9.0

## [2.0.1] - 2019-06-06
### Fixed
- Fixed problem when building with libcurl <= 7.38

## [2.0.0] - 2019-06-02
### Breaking Change
- Dropped support for Node.js 4 and 6
- Prebuilt binary is now statically built with brotli, libssh2, nghttp2, OpenSSL and zlib. brotli, OpenSSL, nghttp2 and zlib versions match their respective versions used by Node.js.
- The minimum libcurl version being tested is now `7.50.0`, which itself is almost 3 years old.  
   The addon will still try to be compatible with old versions up to `7.32.0`, but there are no guarantees.
- `Curl.reset` now correctly resets their instance ([#141](https://github.com/JCMais/node-libcurl/pull/141))
- Previously `Curl.code` had all Curl codes into a single enum like object, that is, it included properties for each `CURLMCode`, `CURLcode` and `CURLSHcode` libcurl enums.  
  Now they are separated, each on their own object:  
   `CURLMCode`  -> `CurlMultiCode`  
   `CURLcode`   -> `CurlCode`  
   `CURLSHCode` -> `CurlShareCode`  
- `DEBUGFUNCTION` now receives a `Buffer` as the `data` argument, instead of a `string`.
- `Easy.send` and `Easy.recv` now return an object, `{ code: CurlCode, bytesSent: number }` and `{ code: CurlCode, bytesReceived: number }` respectively.
- `Curl` class: removed `_` prefix from their private members.  
  Only a breaking change in case you were using internal methods.
- `Curl` class: methods `onData` and `onHeader` renamed to `defaultWriteFunction` and `defaultHeaderFunction`.  
  Only a breaking change in case you were using internal methods.
- `Curl` class: deprecated instance fields `onData` and `onHeader` were removed.  
  Use options `WRITEFUNCTION` and `HEADERFUNCTION` respectively.
- `Curl.dupHandle`, argument `shouldCopyCallbacks` was removed, it was the first one.  
  This is not needed anymore because the previously set callbacks (`onData` and `onHeader`) can now only be set using their respective libcurl options, which is always copied when duplicating a handle.
- `Curl.multi` moved to `Multi.option`
- `Curl.share` moved to `Share.option`
- Following members were moved to their own export:  
  `Curl.auth` -> `CurlAuth`  
  `Curl.pause` -> `CurlPause`  
  `Curl.http` -> `CurlHttpversion`  
  `Curl.feature` -> `CurlFeature`  
  `Curl.lock` -> `CurlShareLock`  
  `Curl.header` -> `CurlHeader`  
  `Curl.info.debug` -> `CurlInfoDebug`  
  `Curl.netrc` -> `CurlNetrc`  
  `Curl.chunk` -> `CurlChunk`  
  `Curl.filetype` -> `CurlFileType`  
  `Curl.fnmatchfunc` -> `CurlFnMatchFunc`  
  `Curl.ftpauth` -> `CurlFtpAuth`  
  `Curl.ftpssl` -> `CurlFtpSsl`  
  `Curl.ftpmethod` -> `CurlFtpMethod`  
  `Curl.rtspreq` -> `CurlRtspRequest`  
  `Curl.ipresolve` -> `CurlIpResolve`  
  `Curl.proxy` -> `CurlProxy`  
  `Curl.pipe` -> `CurlPipe`  
  `Curl.usessl` -> `CurlUseSsl`  
  `Curl.sslversion` -> `CurlSslVersion`  
  `Curl.sslversion.max` -> `CurlSslVersionMax`  
  `Curl.ssh_auth` -> `CurlSshAuth`  
  `Curl.timecond` -> `CurlTimeCond`  
  `Easy.socket` -> `SocketState`  
  And their fields were changed from `SNAKE_CASE` to `PascalCase`.  
  The change in casing was to follow Typescript's Enum naming convention.
- `Curl.protocol` also moved to their own export `CurlProtocol`, no changes were made to fields casing in this case.
- Passing non-integer option value to `Multi.setOpt` will now throw an error.  
  Previously the value was converted to `1` if it was a truthy value, or `0` if otherwise. 
### Fixed
- Fix SigAbort caused by calling v8 `AsFunction` on null value at `Easy::SetOpt`
- Fix SegFault during gargage collection after `process.exit` ([#165](https://github.com/JCMais/node-libcurl/issues/165))
- Using `curl_socket_t` without libcurl version guard on `Easy::GetInfo`
### Added
- Support Node.js 12
- Added missing options:
  - `CURLOPT_DISALLOW_USERNAME_IN_URL`
  - `CURLOPT_DNS_SHUFFLE_ADDRESSES`
  - `CURLOPT_DOH_URL`
  - `CURLOPT_HAPPY_EYEBALLS_TIMEOUT_MS`
  - `CURLOPT_HAPROXYPROTOCOL`
  - `CURLOPT_HTTP09_ALLOWED`
  - `CURLOPT_REQUEST_TARGET`
  - `CURLOPT_FTP_FILEMETHOD` ([#148](https://github.com/JCMais/node-libcurl/pull/148))
  - `CURLOPT_MAXAGE_CONN`
  - `CURLOPT_PROXY_*`
  - `CURLOPT_RTSPHEADER`
  - `CURLOPT_RTSP_REQUEST`
  - `CURLOPT_SOCKS5_AUTH`
  - `CURLOPT_SSH_COMPRESSION`
  - `CURLOPT_TLS13_CIPHERS`
  - `CURLOPT_TIMEVALUE_LARGE`
  - `CURLOPT_TRAILERFUNCTION`
  - `CURLOPT_UPKEEP_INTERVAL_MS`
- Add missing info fields: 
  - `CURLINFO_*_{DOWNLOAD,UPLOAD}_T`
  - `CURLINFO_*_TIME_T`
  - `CURLINFO_FILETIME_T`
- Add `Curl.getVersionInfo()` which returns an object that represents the struct returned from `curl_version_info()`.  
  See their type definition for details: [`./lib/types/CurlVersionInfoNativeBinding.ts`](./lib/types/
- Add `Curl.getVersionInfoString()` which returns a string representation of the above function.  
  It should be almost identical to the one returned from `curl -V`.
- Add `Curl.isVersionGreaterOrEqualThan(x, y, z)` to help test if the libcurl version the addon was built against is greater or equal than x.y.z.
- Add `upkeep` function to Easy and Curl classes. This is a binding for the `curl_easy_upkeep()` function.
- Errors thrown inside callbacks are correctly caught / passed forward (if using multi interface)
- All `Curl` instances now set their `USERAGENT` to `node-libcurl/${packageVersion}` during creation.  
  You change the default user agent string by changing `Curl.defaultUserAgent`, and disable it by setting their value to null.
- `CurlWriteFunc` and `CurlReadFunc` enums with special return codes for their respective options, `WRITEFUNCTION` and `READFUNCTION`.
- Added **experimental** `curly(url: string, options: {})` / `curly.<http-verb>(url: string, options: {})` async api.  
  This API can change between minor releases.
### Changed
- Migrated project to Typescript and added type definitions
- Bumped libcurl version used on Windows to `7.64.1`, which has `nghttp2` support
- Added the `Curl` instance that emitted the event as the last param passed to events, can be useful if using anonymous functions as callback for the events.
  Example:
  ```javascript
    // ...
    curl.on('end', (statusCode, data, headers, curlInstance) => {
       // ...
    })
  ```
- Fix erratic condition when setting option `HEADERFUNCTION` ([#142](https://github.com/JCMais/node-libcurl/pull/142))
- macOS libs should be linked against @rpath ([#145](https://github.com/JCMais/node-libcurl/pull/145))
