Plexus Archiver Release Notes
========================================================================


Plexus Archiver 4.1.0
---------------------

### Improvements

 * [Issue #110][issue-110] - Add option to omit "Created-By" manifest entry.

Plexus Archiver 4.0.0
---------------------

**NOTE:** Because 3.7.0 introduced backward incompatible changes
in the API (new methods in interfaces) we bumped the Plexus Archiver
version to 4.0.0.

Plexus Archiver 4.0.0 requires Java 7.

### Improvements
 * [Issue #105][issue-105] - Fixed performance regression introduced
 in Plexus Archiver 3.0.2. Affected are systems where the retrieval of
 a file's user and group attributes is costly operation.
 * [Pull Request #106][pr-106] - `PlexusIoZipFileResourceCollection`
 performance is improved when working with signed Jar files.

### Tasks

 * [Issue #108][issue-108], [Issue #109][issue-109] - Updated dependencies:
 `plexus-io` to 3.1.1 and `plexus-utils` to 3.1.1.

Plexus Archiver 3.7.0
---------------------

Plexus Archiver 3.7.0 requires Java 7.

### New Features
 * [Pull Request #92][pr-92] - `BaseFileSet` now accepts an array of
 `FileMapper` instances, allowing the name and/or the path of
 entries in the archive to be modified. Thanks to Thomas Collignon.
 * [Pull Request #100][pr-100] - `UnArchiver` now accepts an array of
 `FileMapper` instances, allowing the name and/or the path of the
 extracted entries to be modified. Thanks to Markus Karg.


### Improvements

 * [Issue #98][issue-98] - Now `JarToolModularJarArchiver` does not copy
 the module descriptors (`module-info.class`) to temporary location.
 It adds them directly to the JAR archive.
 * [Issue #101][issue-101], [Pull Request #102][pr-102] - Now `ModularJarArchiver`
 implementations will use the JAR file manifest `Main-Class` attribute
 as module main class if one is not excellently set.

### Bugs

 * [Issue #95][issue-95] - Fixed ZIP entries last modification time
 rounded down on Java 8 or later
 * [Issue #97][issue-97] - Fixed `module-info.class` not being added
 to the modular JAR index file.

### Tasks

 * [Issue #103][issue-103], [Issue #104][issue-104] - Updated dependencies:
 `commons-compress` to 1.18 and `plexus-io` to 3.1.0.

Plexus Archiver 3.6.0
---------------------

Plexus Archiver 3.6.0 requires Java 7. 

### New Features

 * [Pull Request #84][pr-84], [Issue #57][issue-68] - Added Archiver implementation
 (`JarToolModularJarArchiver`) that creates modular JAR files using the JDK jar tool.
 The implementation uses `java.util.spi.ToolProvider` introduced in Java 9,
 so if it is run on Java 7 or 8 the resulting archive will be identical to a
 one created by `JarArchiver` - the module descriptor is not going to be validated
 and no additional information (such as version, main class and packages)
 is going to be added.
 * [Issue #67][issue-67] - Added ability to set the module version and main class
 of a modular JAR file
 * [Pull Request #83][pr-83] - Added new protected method (`postCreateArchive`)
 to `AbstractArchiver` that is called after the archive is created successfully

### Improvements

 * [Pull Request #87][pr-87] - of Levan Giguashvili (odinn1984)
   Snyk eng team to fix a possible security issue.
   (See https://gist.github.com/grnd/eafd7dab7c4cc6197d817a07fa46b2df)

### Bugs

 * [Pull Request #73][pr-73] - Symbolic links not properly encoded
 in ZIP archives
 * [Issue #57][issue-57] - `ZipArchiver` creates archives with inconsistent
 central directory entries
 * [Issue #79][issue-79] - `JarArchiver` and `PlexusIoZipFileResourceCollection`
 leak file descriptors

### Tasks

 * [Pull Request #77][pr-77] - Fixed the way unit tests modify
 the timestamp of a file
 * [Issue #71][issue-71], [Pull Request #72][pr-72], [Issue #76][issue-76],
 [Issue #78][issue-78], [Issue #85][issue-85], [Issue #86][issue-86] -
 Updated dependencies: `commons-compress` to 1.16.1, `plexus-utils` to 3.1.0,
 `org.tukaani:xz` to 1.8 and `plexus-io` to 3.0.1


Plexus Archiver 3.5
-------------------

Plexus Archiver 3.5 requires Java 7. Now Plexus Archiver uses pure Java
implementations to deal with file attributes so the `useJvmChmod` is no
longer used and it is just ignored. `Archiver#setUseJvmChmod`,
`Archiver#isUseJvmChmod()`, `UnArchiver#setUseJvmChmod`,
`UnArchiver#isUseJvmChmod()`,
`ArchiveEntryUtils#chmod( File, int, Logger, boolean )` and
`ArchiveEntryUtils#chmod( File, int, Logger )` are deprecated and are
subject to removal in a future version.

### Improvements

 * [Pull Request #51][pr-51] - More specific exception for cases when
   there are no files to archive. Now `EmptyArchiveException` is thrown
   when you try to create empty archive. Previously the more generic
   `ArchiverException` was thrown.

### Bugs

 * [Issue #47][issue-47] - Archiver follows symlinks on Windows
 * [Issue #53][issue-53] - `AbstractZipArchiver` no longer respects
   `recompressAddedZips`
 * [Issue #58][issue-58] - Creates corrupt JARs

### Tasks

 * [Pull Request #56][pr-56] - Upgrade the minimum required Java version to 7
   and Plexus IO to 3.0.0
 * [Issue #60][issue-60] - Upgrade dependencies.
   `plexus-container-default` to `1.0-alpha-30`,
   `commons-compress` to 1.14, `org.tukaani.xz` to 1.6 and
   `com.google.code.findbugs.jsr305` to 3.0.2

Plexus Archiver 3.4.1
-------------------

### Improvements

 * [Pull Request #87][pr-87] - of Levan Giguashvili (odinn1984)
   Snyk eng team to fix a possible security issue.
   (See https://gist.github.com/grnd/eafd7dab7c4cc6197d817a07fa46b2df)

Plexus Archiver 3.4
-------------------

### Bugs

 * [Issue #45][issue-45] - Default `ArchiveManager` does not support
   `tar.xz` and `tar.snappy` file extensions
 * [Issue #46][issue-46] - `JarSecurityFileSelector` needs to support
   signature files ending in `.EC` or `.ec`

Plexus Archiver 3.3
-------------------

### Improvements

 * [Issue #42][issue-42] - No need to fallback to unicode path extra field
   policy `NOT_ENCODEABLE`
 * [Issue #39][issue-39] - Updated to stop falling back to the unicode path extra field
   policy `NOT_ENCODEABLE`. If a name is not encodeable in UTF-8, it also is not
   encodeable in the extra field.
   Updated to always add the Info-ZIP Unicode Path Extra Field when creating an
   archive using an encoding different from UTF-8 instead of only when a name is
   not encodeable. Additionally support that extra field when unarchiving.
 * [Issue #38][issue-38] - Downgrade `PrintWriter` to `Writer` in `Manifest`
 * [Issue #36][issue-36] - `Created-by` entry does not reflect who created the JAR
 * [Issue #35][issue-35] - Replace `defaultManifest.mf` with inline code
 * [Issue #17][issue-17] - Remove unnecessary conversion in `Manifest#Attribute#write`
 * [Issue #16][issue-16] - Manifest entry `Archiver-Version` is incomplete/wrong.
   Entry does not reflect the archiver version. Remove since it
   adds not information it pretends to add.
 * [Issue #5][issue-5] - Added proper bound on memory usage, patch by Björn Eickvonder
 * [Pull Request #41][pr-41] - Support the Info-ZIP Unicode Path Extra Field.

### Bugs

 * [Issue #43][issue-43] - Updated to stop failing creating `Created-by` manifest entries,
   when the version of the archiver cannot be determined
 * [Issue #37][issue-37] - Deprecate `Manifest(Reader)` and update all related
   Implemenation does not properly map characters to map and makes assumptions
   about character encoding which might lead to failures.
   Deprecate and rely on Java Manifest reader to do the right thing.
 * [Issue #20][issue-20] - `Manifest#write` blindly casts bytes to chars
 * [Issue #18][issue-18] - `Manifest#Attribute#writeLine` does not properly calculate
   max line length

### Tasks

 * [Issue #40][issue-40] - Updated to upgrade `plexus-utils` to latest patch release
