0.21.0

Features and enhancements

• [core] Add a custom type system which allows defining own complex types.
  (#1216, #1224)
• [core] Add a new built-in type: Port. Port specifies a board hardware pin
  like A4 or D4. Port specification became more straightforward rather than
  plain numbers used before. (#1232)
• [core] Add a new built-in type: Byte. A byte is a group of eight bits
  specified in a binary, decimal, or hexadecimal form. (#1192)
• [core] Clarify error messages related to generic type conflicts. (#1246)
• [nodes] Add byte-to-number and number-to-byte conversion nodes to
  xod/bits. (#1186)
• [nodes] Make nodes in xod/bits use the new Byte type. (#1261)
• [nodes] Make nodes in xod/common-hardware use the new Byte and Port types.
  They now also expose unified pins for an explicit update, update
  acknowledgment, and error signaling. (#1274)
• [nodes] Nodes related to mathematics moved from xod/core to
  xod/math (#1251)
• [nodes] Nodes related to general purpose input/output moved from xod/core
  to xod/gpio (#1256)
• [nodes] Nodes for the I²C bus communication moved from xod/core to
  xod/i2c (#1270)
• [tutorial] Links in the welcome-to-xod tutorial no longer use goo.gl link
  shortener and point to web-pages directly (#1217)

Deprecations and removals

• All nodes related to mathematics in xod/core are deprecated now. Use
  corresponding nodes from xod/math instead.
• Nodes analog-input, pwm-output, digital-input, and digital-output
  from xod/core are deprecated now. Use analog-read, pwm-write,
  digital-read, digital-write from the new xod/gpio, or
  xod/common-hardware/analog-sensor instead.
• Plain numbers for pins defining a port are deprecated now. Although value 3
  is still valid, prefer explicit A3 or D3. IDE will auto-correct wrong
  values on input commit.
• Plain numbers for pins storing a byte are deprecated now. Although value 3
  is still valid, prefer explicit 3d, 03h, or 11b. IDE will auto-correct
  wrong values on input commit.

Bug fixes

• [core] Correctly pick up values bound to generic terminals and use them as
  default values for pins created by these terminals. (#1250)
• [ide] Fix some cases when generic pins were not colored even if their types
  can be deduced. (#1248)
• [ide] Reset project preferences when creating a new project. (#1252)
• [ide] Make toolchain installation immune to download interruptions. (#1255)
