TOPP tools:
  Changes:
    all:
      - BREAKING: Command-line duplicate parameter behavior changed (#8670, fixes #5345)
        When a parameter is specified multiple times on the command line, the LAST occurrence now wins
        (previously, the FIRST occurrence was used). This enables the nextflow pattern of using ${ext.args}
        at the end of commands to override hardcoded defaults. A warning is issued when duplicates are detected.
        Example: tool -param default -param override  # Now uses 'override' (previously used 'default')
      - Improved error messages for command-line parameter errors (#8670)

----                                OpenMS 2.0     (released 4/2015)                   ----
-------------------------------------------------------------------------------------------
Release date: February 2015

OpenMS 2.0 is the first release after the switch to git and a complete overhaul of the
build system. It introduces a considerable number of new features and bug fixes.

Furthermore, we removed the dependency to GSL and replaced the functionality using
Eigen3 and Wildmagic. Thus, the OpenMS core and the full build are now under a more
permissive non-GPL (e.g., Apache or BSD) license.

File formats:
  - mzQuantML support (experimental)
  - mzIdentML support (experimental)
  - mzTab support (experimental)
  - Indexed mzML support
  - Support for numpress encoding in mzML
  - Major speed improvement in mzML / mzXML parsing (up to 4x for some setups)

TOPPView:
  - Support for visualizing mass fingerprinting hits from featureXML along with their raw spectra in MS1
  - Improved "Tools" -> "Goto" dialog
  - Improved display of m/z, RT, and intensity values 1D and 2D view

New tools:
  - FeatureFinderIdentification -- Detects features in MS1 data based on peptide identifications (TOPP)
  - FeatureFinderMultiplex -- Determination of peak ratios in LC-MS data (TOPP)
  - FidoAdapter -- Runs the protein inference engine Fido (TOPP)
  - LowMemPeakPickerHiRes -- Finds mass spectrometric peaks in profile mass spectra (UTIL)
  - LowMemPeakPickerHiRes_RandomAccess -- Finds mass spectrometric peaks in profile mass spectra (UTIL)
  - MRMTransitionGroupPicker (UTIL)
  - MSGFPlusAdapter -- MS/MS database search using MS-GF+ (TOPP)
  - MetaboliteSpectralMatcher -- Find potential HMDB ids within the given mass error window (UTIL)
  - OpenSwathWorkflow -- Complete workflow to run OpenSWATH (UTIL)
  - PeakPickerIterative -- Finds mass spectrometric peaks in profile mass spectra (UTIL)
  - RTAnnotator -- Annotates identification files that are missing the RT field (UTIL)
  - SimpleSearchEngine -- Annotates MS/MS spectra using SimpleSearchEngine (UTIL)
  - TopPerc -- Facilitate input to Percolator and reintegrate (UTIL)

Deprecated tools:
  - DBExporter -- Exports data from an OpenMS database to a file (TOPP)
  - DBImporter -- Imports data to an OpenMS database (TOPP)
  - FeatureFinderRaw -- Determination of peak ratios in LC-MS data (TOPP)
  - SILACAnalyzer -- Determination of peak ratios in LC-MS data (TOPP)

Status changes:
  - PhosphoScoring (UTIL -> TOPP)

Tools with major changes:
  - OpenSWATH now supports MS1 extraction and labelled workflows
  - OpenSWATHWorkflow single binary (high performance integrated workflow)
  - IsobaricAnalyzer now supports TMT 10-plex

General:
  - Removed GSL dependencies
  - Introduced low memory versions of various algorithms
  - OpenMS now offers a single interface for different implementations to access mass spectrometric data
      - in memory
      - on disk with index
      - cached on disc for fast access
    as well as a chainable, low memory sequential processor of MS data (using a separate interface)
  - pyOpenMS now supports python 3.x
  - Refactored AASequence, major speed improvement (~40x) for construction of unmodified sequences

Third party software:
  - Added Fido support
  - Added MS-GF+ support

Changes to the Build System / Package System:
  - Restructured repository layout and build system
  - Added support for Travis CI
  - Simplified pyOpenMS build system
  - Support for Visual Studio 2013

------------------------------------------------------------------------------------------
Release date: August 2013

OpenMS 1.11 is the first release with fully integrated Python bindings (termed pyOpenMS).

----                                  OpenMS 1.9                                      ----
------------------------------------------------------------------------------------------
Release date: February 2012

OpenMS 1.9 has some major changes in TOPP tool names and usage. Therefore all .ini files
for "typed" TOPP tools (i.e. those with a "type" parameter) built with OpenMS 1.8 and below
are incompatible! To fix your old .ini and .toppas files use the new
INIUpdater tool (see its documentation and the TOPP documentation in general).

OpenMS 1.9 removed support for Mac OS X 10.5.

Documentation:
- new Quickstart tutorial
- dedicated and reworked TOPPAS tutorial

TOPPView improvements:
-MODIFIED:
  - ConsensusFeatures can now be colored using MetaValues
  - better grid line drawing/calculation, extracted AxisPainter class
  - IdentificationView:
    - added automatic labeling with peptide fragment sequence
    - theoretical spectrum is now hidden by default (labeling contains relevant information for most use cases)
    - automatic zoom to measured MS2 data range

TOPPAS improvements:
	- TOPPAS allows for interactive download of preconfigured TOPPAS pipelines from OpenMS homepage
	- "Recycling" mode for nodes, useful for database input files (see docu for details)
- more flexible pipeline design for Merger nodes
- Merger nodes (merge, merge all) renamed to "Merge" (one round) and "Collect" (all rounds)


TOPP tools:
- ADDED:
  - MapStatistics: statistics for low level quality control
  - EICExtractor: quantify known RT, m/z locations in one or many LC/MS maps and align them
  - MassTraceExtractor: annotate mass traces in centroided LC/MS maps - useful for metabolomics and top-down proteomics (use FeatureFinder tools for peptides)
  - FeatureFinderRaw: feature finding on raw data
	- FeatureFinderMetabo: feature finding for metabolites
  - IDConflictResolver: resolve ambiguous annotations of features with peptide identifications
- MODIFIED:
  - FeatureFinder: split into FeatureFinderMRM, FeatureFinderCentroided, FeatureFinderIsotopeWavelet
  - FeatureLinker: split into FeatureLinkerLabeled, FeatureLinkerUnlabeled, FeatureLinkerUnlabeledQT
  - FeatureLinker tools remove unneeded data after loading featureXML files to conserve memory
  - MapAligner: split into MapAlignerIdentification, MapAlignerPoseClustering, MapAlignerSpectrum, and MapRTTransformer
  - model parameters of MapAligner tools are now set in the INI file
  - MapAlignerIdentification: don't fail if parameter "min_run_occur" is set too high, warn and use possible maximum instead
  - NoiseFilter: split into NoiseFilterGaussian and NoiseFilterSGolay
  - PeakPicker: split into PeakPickerWavelet and PeakPickerHiRes
  - PILISModel: split into PILISModelCV, PILISModelTrainer, and PILISSpectraGenerator
  - MascotAdapterOnline: now supports Mascot 2.3 servers
  - ProteinQuantifier: added support for writing idXML (suitable for export to mzTab)
  - IDFileConverter: when reading pepXML, fail if the requested experiment (parameters "mz_file"/"mz_name") could not be found in the file
- REMOVED:
  - AndiMS/NetCDF is no longer supported on any platform
  - removed IDDecoyProbability tool

UTIL tools:
- ADDED:
  - INIUpdater: update INI and TOPPAS files
  - TransformationEvaluation: evaluate a (RT) transformation by applying it to a range of values
- REMOVED:
  - CaapConvert
  - UniqueIdAssigner
  - HistView

Changes to the Build System:
	- TOPPAS now requires Qt's Webkit library
	- Use CMAKE_BUILD_TYPE instead of OPENMS_BUILD_TYPE (removed)
	- Use CMAKE_FIND_ROOT_PATH instead of CONTRIB_CUSTOM_DIR (deprecated)
  - Removed AndiMS, NetCDF and dependencies
	- Removed dependency to imslib, relevant classes were moved directly to OpenMS/CHEMISTRY/MASSDECOMPOSITION/IMS
- OpenMS now supports ctests functionality for optimized and parallel testing (see ticket #363)

Fixed Issues: (see also http://sourceforge.net/apps/trac/open-ms/report)

  - FileInfo: improved formatting of output
  - TextExporter: unified output formats
  - FileConverter: added conversion to consensusXML
  - ProteinQuantifier: redefined meaning of parameter combination "top 0"/"consensus:fix_peptides"
