# ChangeLog for time-manager
## 0.3.0
* New architecture. The backend is switched from the designated thread
to GHC's System TimerManager. From this version, this library is
just wrapper APIs of GHC's System TimerManager. Unlike v0.2 or
earlier, callbacks are executed at the exact time. System
TimerManager uses a PSQ (a tree) while v0.2 or earlier uses a list.
So, this version hopefully scales better.
* Deprecated functions: `stopManager`, `killManager` and `withManager'`.
* `tickle` sets the specified timeout from now.
* `pause` is now identical to `cancel`.
* `resume` is now re-registration of timeout.
* The signature of `withHandle` is changed.
## 0.2.4
* Providing `isAllGone`.
* Providing emptyHandle.
## 0.2.3
* Exporting defaultManager.
## 0.2.2
* `initialize` with non positive integer creates a time manager
which does not maintain timeout.

## 0.2.1
* Export KilledByThreadManager exception
[#1016](https://github.com/yesodweb/wai/pull/1016)
## 0.2.0
* Providing `System.ThreadManager`.
* `withHandle` catches `TimeoutThread` internally.
It returns `Nothing` on timeout.
## 0.1.3
* Providing `withHandle` and `withHandleKillThread`.
## 0.1.2
* Holding `Weak ThreadId` to prevent thread leak again
[#1013](https://github.com/yesodweb/wai/pull/1013)
## 0.1.1
* Removing `unliftio`.
## 0.1.0
* [#986](https://github.com/yesodweb/wai/pull/986)
* Change behavior of `cancel` to immediately remove the `Handle` from the
reaper's workload, rather than waiting for timeout.
* Using auto-update v0.2.0.
