Major changes for arb-7.0 (1 Sep 2021):

 - ARB PARSIMONY
   * topology optimization
     - now (by default) strictly restricted to marked/visible parts of the tree (#640)
     - restriction now customizable (marked/all; visible/all)
     - tree costs for protein-data were not independent from root-position (as expected by model; #633).
       Caused infinite running optimization under some circumstances.
     - optimize-modes now strictly restrict to clicked subtrees. single/repeated optimization possible.
     - KL-optimizer
       * static path reduction slightly changed meaning. changed default settings.
       * removed randomness (was just covering some bugs)
       * improved general optimization speed
   * branchlength calculation
     - "forgot" to recalculate lengths under some conditions. fixed.
     - is now independent of tree-root position (#641)
   * adding species
     - 'add partial species' failed if two partial species had NO overlap (#609). fixed.
     - in 'add species + NNI' local optimization quality depended on insert position. fixed.
     - insertion of multiple species is now done independently (=unordered; #643)
     - performance improved (esp. for many added species/big trees; #643)
   * generally improved combine performance (using SSE)
   * generally reduced the number of performed combines (skipping many useless)
   * added function to randomize (parts of) the tree
   * warns about insufficient sequence data (e.g. as result of too restrictive filtering; #631)
   * fixed 'RESTORE' (crashed after deleting species from tree; #528)
   * corrected handling of dots ('.') while combining ancestor sequences
   * fixed a bunch of internal bugs (#620, #627, #645, ...)
   * added species-info mode
 - added missing translation tables (genetic codes 24-31)
 - added amino acid code Xle(=J), which means Ile(=I) or Leu(=L)
 - DNA realigner
   * several unjustified failures will no longer happen (fixes #419 and most likely #145)
     - correctly re-syncs after 'X' (if possible at all)
     - no longer fails for 'B', 'J' and 'Z'
     - accepts 3 or more consecutive IUPAC codes in DNA
   * added option to cut-off DNA sequence (was done at end of sequence by old version. fixed)
   * fixed several minor bugs (#563,..)

 - support for extra database compression (using gzip, bzip2, xz; #665); databases cannot be opened by versions before arb-7.0
 - ARB_EDIT4:
   * display selected database fields as flags (allowing to toggle their value; #261).
     Example use: easily mark sequence as "curated" after manually checking its alignment.
   * allow to load missing SAIs
   * "view differences" to a reference sequence:
      - customizable:
        * char used for "equality" (i.e. what is displayed where a sequence is equal to selected sequence)
        * case-sensitivity
        * ignore different gap-types

      - added hotkey to toggle mode: CTRL-D

     - fixed and updated documentation
   * added species-info mode + database save (#52,#362)

   * preserve gap-type ('-' vs '.') and upper-/lower-case of original alignment
   * no longer ask what to do with aligned sequence, just overwrite it
     - only warn about real sequence changes (so please do NOT ignore from now on!)
 - config-managers:
   * possibility to restore factory defaults
   * added comment field for configurations
   * added them throughout arb (#647)

 - tree (display) options:
   * fine grained scaling

   * bootstrap values (filter by upper/lower limits, display position/styles, on/off toggle; #614)
   * diagonal branch style (#578)
   * parent branch position
   * all options are now also supported by ARB_PARSIMONY
