0.20.0

Features and enhancements

• [core] Implement generic nodes. Such nodes may work with values type of which
  is not known in advance. See the user’s guide to learn more.
• [core] Values of any type bound to pins are now stored as-is using strings.
  As a good side effect, one may now bind scientific notation numbers (3e-6
  for 0.000003), infinity (+Inf, -Inf), and NaN in the Inspector.
  Strings are now always enquoted. When you deal with regular (non-generic)
  pins, the required quotes will be added for you automatically. (#1164)
• [ide] Allow relinking of occupied input pins. Now instead of showing an
  error, IDE removes the existing link, replacing it with the new one. (#1120)
• [ide] Preserve window position and size across launches. (#1134)
• [ide] The main window now can be as small as 700px in width. It allows quicker
  1-to-1 screenshoting for docs and Medium. (#1135)
• [core] Create marker nodes to indicate a patch is an internal utility or
  deprecated legacy. In IDE’s project browser such nodes are hidden by default.
  To show them click the funnel button in the pane header. (#1137, #1141)
• [cli] Implement a simple tabular testing feature that should become an xUnit
  of XOD. (#1148)
• [c++] Add isSettingUp node API function to check whether the current
  evaluation is a part of the very first transaction which is run in setup().
  (#1152)
• [core] More informative errors for many “bad program” scenarios. Now they
  always include a full path trace from the entry point patch to the patch
  having a problem. (#1155, #1156)
• [nodes] xod/core/equal made generic and now can handle strings.
• [nodes] xod/core/select made generic and now can handle strings and booleans.

Deprecations and removals

• [nodes] cast-*-to-* are deprecated. Use specialized nodes like
  format-number instead.
• [nodes] debounce-boolean is deprecated. Use generic xod/core/debounce
  instead.
• [nodes] defer-* are deprecated. Use generic xod/core/defer instead.
• [nodes] gate-* are deprecated. Use generic xod/core/gate instead.
• [nodes] BREAKING ❗ The original gate (without a type suffix) is
  renamed to xod/core/branch.
• [nodes] if-else-string is deprecated. Use generic if-else instead.
• [nodes] nth-number is deprecated. Use generic nth-input instead.

Bug fixes

• [ide] Remove actual C++ implementation when deleting the
  not-implemented-in-xod node. (#1142)
• [ide] Make vertical and horizontal lines (links and nodes’ edges) always
  sharp (#1168)
