2+5.35.1

3+------

4+

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

83+ Onsem)
