5−Bug fixes:

6− * Fixed a build issue with a test program.

7−

8−5.35

9−----

10−

11−New features:

12− * Add support for 24-bit color (thanks @u-quark). This change

13− updates Vty to look at the `COLORTERM` environment variable that is

14− conventionally used to advertise support for truecolor escape

15− sequences. The change also updates the Vty demo to demonstrate

16− 24-bit colors. This change also adds a new data type, `ColorMode`,

17− to represent the color mode in use, as well as an `Output` interface

18− field, `outputColorMode`, to track the active color mode and use it

19− to clamp emitted color escape sequences to the active color range.

20−

21−API changes:

22− * All types in `Graphics.Vty.Input.Events` now have strict constructor

23− fields.

24− * Internal events are now wrapped in a new `InternalEvent` type to

25− improve how signal handling is done. This change modifies the `Input`

26− type's event channel API to produce `InternalEvents`, not `Events`.

27− The new `InternalEvent` either wraps `Event` with the `InputEvent`

28− constructor (the previous behavior) or indicates that Vty resumed

29− after handling a signal using the `ResumeAfterSignal` constructor.

30− This change avoids the previous use of `EvResize` with lazy exception

31− arguments as a sentinel value for `ResumeAfterSignal`.

32−

33−Other enhancements:

34− * Bracketed paste parsing performance has been greatly improved thanks

35− to benchmarking and optimization work by @iphydf. As part of that

36− work, Vty now uses bytestrings rather than Strings internally when

37− parsing input to look for events.

38− * The `\b` value is now interpreted as `KBS` (thanks @vglfr)

39−

40−5.34

41−----

42−

43−API changes:

44− * Added an `NFData` instance for `Event` (thanks Mario Lang)

45− * Removed `Monoid` and `Semigroup` instances for `Attr` and

46− `MaybeDefault`. This change removed the instances because they were

47− misbehaved; merging `Attr` and `MaybeDefault` values with these

48− instances resulted in field value losses. For example, before this

49− change,

50−```

51−(defAttr `withForeColor` blue) <> (defAttr `withBackColor` green)

52−```

53− would result in just

54−```

55− (defAttr `withBackColor` green)

56−```

57− because the instances were designed to favor the right-hand

58− arguments' fields even if they had not been explicitly set

59− (a consequence of the `MaybeDefault` `Semigroup` instance).

60− While that behavior was sensible specifically in the context of

61− `Graphics.Vty.Inline`, it wasn't a useful user-facing API and it made

62− for surprising instance behavior. Since there is actually no good way

63− to handle this in a `Semigroup` instance for `Attr` -- some choices

64− have to be made about how to merge two attributes' foreground colors,

65− and that won't be much better than what we had -- the instance was

66− just removed.

67−

68−

69−5.33

70−----

71−

72−API changes:

73−* The `Cursor` type got a new `PositionOnly` constructor for cursor

74− placement without visibility.

75−

76−Package changes:

77−* Relaxed upper bound for `random`

78−* Updated `microlens` bounds to allow 0.4.12

79−

80−Other improvements:

81−* Various hlint-driven improvements (thanks Willem Van Onsem)

82−* The implementation of `color240` was improved (thanks (Willem Van
