  * More precise obtuse-angle arcs.
  * Minor addition to the manual.
  * Non-LaTeX error-handling cleanup.
  * Line thickness recovery parameter enabled.
  * Redundant code dating from pascal conversion removed.
  * Robustness fixes.
  * Improved robustness for fuzzed input.
  * Added colored svg sprintf text and % appended to selected outputs.
  * Shift operation bugfix.
  * Improved error messaging; additional distribution examples.
  * CVE-2021-33390: Use-after-free in thedeletestringbox() (boo#1214501).
  * CVE-2021-33388: Heap Buffer Overflow in themakevar() (boo#1214502).
  * CVE-2021-32422: Buffer Overflow in theyylex() (boo#1214503).
  * CVE-2021-32421: Heap Use-After-Free in thedeletestringbox() (boo#1214504).
  * CVE-2021-32420: Heap-based Buffer Overflow in thestorestring() (boo#1214505).

- update to 2020.06.01:
  * SVG text adjustments; GCC-10 conformance.
  * Commas protected by brackets; zero-repetition "for" loop bugfix
    under bison.
  * Fix of environment variable scope, arc attribute; improved error
    messages; generalized macro definition.
  * Corrected typos, copyright notices, version number, string treatment.
  * Bugfix for buffer overflow with extreme arguments of wfloat().
  * This is a major clone of the previous distribution, which
  contained compilable C code together with the original pascal
  source.  The pascal was translated to C code using p2c,
  which was included, and parsing was automated by a custom
  compiler-compiler which was also provided.  The current
  package includes C source only with parsing automated using
  GNU bison.  The original lexical analyser has been kept. To
  avoid introducing bugs, the C code has been changed only to
  accommodate bison; some p2c idiosyncrasies remain. The result
  is functionally identical to the previous version for correct
  input.
