  - `extractFiles` => `extract`
  - `addFiles` => `add`
  - `deleteFiles` => `delete`
  - `archiveFiles` => `archive`
  - `canOpenArchive` => `canOpen`
  - Old methods are marked as deprecated and will be deleted in future releases.

  - `UnifiedArchive::detectArchiveType` - use `Formats::detectArchiveFormat` instead
  - `UnifiedArchive::archiveDirectory`/`archiveFile` - use `UnifiedArchive::archive` instead
  - `UnifiedArchive::canCreateType` - `Formats::canCreate`

- Added method to get info about ready to archive files: `UnifiedArchive->prepareForArchiving($fileOrFiles, $archiveName = null)`
- Added method to create archive in memory: `UnifiedArchive::createInString()` and `BasicDriver::CREATE_IN_STRING` ability constant
- Added new pure driver for Zip/Tar(gz/bz2) - SplitbrainPhpArchive.

## 1.1.7 - Jul 31, 2022
- `open` does not throw an Exception, it returns null
- returned deleted methods in UnifiedArchive: `canOpenArchive`, `canOpenType`, `canCreateType`, `getArchiveType`, `detectArchiveType`, `getFileResource`, `getArchiveFormat`, `isFileExists`, `getArchiveSize`, `countCompressedFilesSize`, `countUncompressedFilesSize`.

## 1.1.6 - Jul 31, 2022
**BC-breaking changes**:
- Changed signature: `UnifiedArchive::open($filename, string|null $password = null)` => `UnifiedArchive::open($filename, array $abilities = [], string|null $password = null)`. Right now if second argument is string, it will be treated as password (for BC-compatability).
- `open` throws an Exception when format is not recognized or there's no driver that support requested abilities.
- `addFiles`/`deleteFiles`/`getComment`/`setComment` throws an Exception when driver does not support this ability.
- Deleted methods in UnifiedArchive: `canOpenArchive`, `canOpenType`, `canCreateType`, `getArchiveType`, `detectArchiveType`, `getFileResource`, `getArchiveFormat`, `isFileExists`, `getArchiveSize`, `countCompressedFilesSize`, `countUncompressedFilesSize`.

**New features**:
- Added passing needed abilities to **UnifiedArchive::open()** to select a better driver:
    ```php
    use wapmorgan\UnifiedArchive\Abilities;use wapmorgan\UnifiedArchive\Drivers\Basic\BasicDriver;

    # opens an array with driver, that supports content streaming and appending
    $archive = \wapmorgan\UnifiedArchive\UnifiedArchive::open('archive.7z', [Abilities::STREAM_CONTENT, Abilities::APPEND]);
    # if not specified, uses OPEN or OPEN_ENCRYPTED check, if password passed
    ```
- Added `UnifiedArchive::test($files = [])` (and `cam files:test` command) to test archive contents (compare actual control sum with stored crc32).
- More informative output in commands: `system:drivers`, `system:formats`, `system:format`, added command `files:test`.
- Added driver abilities to select better driver.

**Driver changes:**
- Added `NelexaZip` pure-PHP driver.
- Added `Iso` driver extraction ability.
- Added commenting-ability for `SevenZip` driver (via `descript.ion` file in archive).

## 1.1.5 - Jun 28, 2022

**New features**:
- Reimplemented `cam` (console utility) - now it's on symfony/console and supports all features and more functions (folders, types) of UA.
- Added more detailed installation instructions (`./vendor/bin/cam system:drivers`) of specific drivers: AlchemyZippy, Cab, Iso, Lzma, Rar, SevenZip, TarByPear.
- Added ability to track progress of archive creation - new argument `?callable $fileProgressCallable` of `UnifiedArchive::archiveFiles()`.
- Added ability to **pass few directories to be placed in one in-archive directory** in archiving/appending (`addFiles()`/`archiveFiles()`)
    ```php
    [
        '' => ['./folder1', './folder2'],
        'README.md' => './subfolder/README.md'
    ] # Archive will have all folder1, folder2 contents in the root and README.md
    ```

**Fixed**:
- Fixed `extract()` and `listContent()` and their result of **PclZip** interface (`UnifiedArchive::getPclZipInterface()`) to correspond to original library (object => array).
- Added tests on archiving, extraction and for PclZip-interface.

**Format changes**:
- Fixed counting of extracted files when extracting the whole archive in `TarByPear, TarByPhar, Zip`.
- Fixed calculation archive entry compressed size (approximately) and modification time, implemented entry content streaming in `TarByPhar`.

## 1.1.4 - Dec 21, 2021
Disabled `rar` for SevenZip driver.

## 1.1.3 - May 2, 2021

**Changed format of `$files` in `archiveFiles()` and `addFiles()`**
```php
[
    '/var/www/log.txt',                // will be "/var/www/log.txt"
    'log2.txt' => '/var/www/log2.txt', // will be "/log2.txt"
    '/var/www/site',                   // will be "/var/www/site"
    'site2' => '/var/www/site2',       // will be "/site2"
]
```

Old format also works, but there can be a bad case. If you have */var/www/log2.txt* and *log2.txt* (in current directory) and pass following:
```php
[
'/var/www/log2.txt' => 'log2.txt',
]
```
it will archive *log2.txt* as */var/www/log2.txt* in an archive (new behaviour).

**New features**:
- Added `Formats::canStream()` to check if an archive files can be streamed.
- Added ability to create archives, encrypted with password (only *zip* (`Zip`, `SevenZip`) and *7z* (`SevenZip`)) - added nullable `$password` argument to:
  - `UnifiedArchive::archiveFiles($fileOrFiles, $archiveName, $compressionLevel = BasicDriver::COMPRESSION_AVERAGE, $password = null)`
  - `UnifiedArchive::archiveFile($file, $archiveName, $compressionLevel = BasicDriver::COMPRESSION_AVERAGE, $password = null)`
  - `UnifiedArchive::archiveDirectory($directory, $archiveName, $compressionLevel = BasicDriver::COMPRESSION_AVERAGE, $password = null)`
- Added `UnifiedArchive->getMimeType()` to get mime type of archive.
- Added `UnifiedArchive->getComment()` to get comment of an archive. Available only in `Zip` and `Rar` drivers, others return `null`.
- Added `UnifiedArchive->setComment(?string $comment)` to set comment. Available only in `Zip`.
- Added filter in `UnifiedArcihve->getFileNames()`. If works as `fnmatch()` does.
- Added ability to iterate over archive and access files data as array:
```php
$a = \wapmorgan\UnifiedArchive\UnifiedArchive::open('tests/archives/fixtures.7z');
foreach ($a as $file => $data) {
    echo $file.PHP_EOL;
 }

$file_data = $a['filename'];
```

**Fixed:**
- Fixed `SevenZip` driver: disabled _tar.gz, tar.bzip2_ support as it isn't supported properly and described which formats driver can create, append, modify and encrypt.

**Methods renamed** (old exist, but marked as deprecated):
- `UnifiedArchive->getArchiveFormat` -> `UnifiedArchive->getFormat`.
- `UnifiedArchive->getArchiveSize` -> `UnifiedArchive->getSize`.
- `UnifiedArchive->countCompressedFilesSize` -> `UnifiedArchive->getCompressedSize`.
- `UnifiedArchive->countUncompressedFilesSize` -> `UnifiedArchive->getOriginalSize`.
- `UnifiedArchive->getFileResource` -> `UnifiedArchive->getFileStream`.
- `UnifiedArchive->isFileExists` -> `UnifiedArchive->hasFile`.

## 1.1.2 - Mar 1, 2021

Fixed working with *tar.xz* archives.

## 1.1.1 - Feb 13, 2021

## 1.1.0 - Feb 13, 2021
**New features**:
- Added ability to open archives encrypted with password - added `$password` argument to `UnifiedArchive::open($fileName, $password = null)`. Works only with: zip, rar, 7z.   
- Added ability to adjust compression level for new archives - added `$compressionLevel` argument (with default `BasicDriver::COMPRESSION_AVERAGE` level) to:
    - `UnifiedArchive::archiveFiles($fileOrFiles, $archiveName, $compressionLevel = BasicDriver::COMPRESSION_AVERAGE)`
    - `UnifiedArchive::archiveFile($file, $archiveName, $compressionLevel = BasicDriver::COMPRESSION_AVERAGE)`
    - `UnifiedArchive::archiveDirectory($file, $archiveName, $compressionLevel = BasicDriver::COMPRESSION_AVERAGE)`
  Works only with: zip, gzip.
- Added ability to append the archive with a file from string - added `addFileFromString` method:
  `UnifiedArchive->addFileFromString(string $inArchiveName, string $content)`.
- Added tests for format support:
    * `Formats::canOpen()`
    * `Formats::canCreate()`
    * `Formats::canAppend()` - check if file can be added to an archive
    * `Formats::canUpdate()` - check if archive member can be removed
    * `Formats::canEncrypt()` - check if encrypted archive can be opened

**Format changes**:
- Extended *SevenZip* driver: now it supports a lot of formats (7z, zip, rar, iso, tar and so on).
- Added *AlchemyZippy* driver: it works via command-line programs for zip, tar, tar.gz and tar.bz2.

## 0.1.1 - Sep 21, 2018
API changes:
* **Changed algorithm of files list generation in `archiveFiles()` and `addFiles()`**:
    ```php
    // 1. one file
    $archive->archiveFiles('/var/www/site/abc.log', 'archive.zip'); // => stored as 'abc.log'
    // 2. directory
    $archive->archiveFiles('/var/www/site/runtime/logs', 'archive.zip'); // => directory content stored in archive root
    // 3. list
    $archive->archiveFiles([
          '/var/www/site/abc.log' => 'abc.log', // stored as 'abc.log'
          '/var/www/site/abc.log', // stored as '/var/www/site/abc.log'
          '/var/www/site/runtime/logs' => 'logs', // directory content stored in 'logs' dir
          '/var/www/site/runtime/logs', // stored as '/var/www/site/runtime/logs'
    ], 'archive.zip');
    ```
* **Disabled paths expanding in `extractFiles()` and `deleteFiles()` by default**.

    If you need to expand `src/` path to all files within this directory in archive, set second argument `$expandFilesList` argument to `true`.
    ```php
    $archive->extractFiles(__DIR__, 'src/', true);
    $archive->deleteFiles('tests/', true);
    ```

* Added new element in `archiveFiles()` result in emulation mode. Now it returns an archive with 4 elements: new `type` element with archive type.

Fixes:
* Fixed **LZW-stream** (.tar.Z) wrapper (before it didn't work).
* Fixed **ISO** archives reading (before archive size could be calculated wrong).
* Fixed **CAB** archives extraction in `getFileContent($file)` (before it didn't work).
* Improved extraction in `getFileContent($file)` for **RAR** archives by using streams (before it did extract file in temporarily folder, read it and then delete it).

Improvements:
* Added `isFileExists($file): bool` method for checking if archive has a file with specific name.
* Added `getFileResource($file): resource` method for getting a file descriptor for reading all file content without full extraction in memory.
* Added `canOpenArchive($archiveFileName): bool` and `canOpenType($archiveFormat): bool` static methods to check if specific archive or format can be opened.
* Added `detectArchiveType($fileName): string|false` static method to detect (by filename or content) archive type.
* Added `addFile($file, $inArchiveName = null)` / `addDirectory($directory, $inArchivePath = null)` to add one file or one directory, `archiveFile($file, $archiveName)` / `archiveDirectory($directory, $archiveName)` to archive one file or directory.

Miscellaneous:
* Added simple tests.
* Added `phar` distribution.

## 0.1.0 - Apr 11, 2018
API changes:
* Renamed methods `extractNode()` → `extractFiles()`, `archiveNodes()` → `archiveFiles()`. Original method are still available with `@deprecated` status.
* `getFileData()` now returns `ArchiveEntry` instance instead of `stdClass`. Original object fields are still available with `@deprecated` status.
* `addFiles()` and `deleteFiles()` now return false when archive is not editable.

Improvements:
* Added checks of archive opening status in constructor: now an `Exception` will be throwed if archive file is not readable.
* Some changes in `archiveNodes()` about handling directory names.
* Fixed archive rescan in `addFiles()` and `deleteFiles()`.

Miscellaneous:
* Removed example scripts (`examples/`).
* Code changes: added comments.
