## 0.5.0.0 - unreleased
* Readme added :)
* Old parser replaced with an incremental implementation
* General overhaul of the codebase
* Partial Haddock coverage
The 0.5.* releases should be able to handle large event logs and logs that have been cut off abruptly, e.g. from executable runs that resulted in crashes.
This release should be *mostly* backwards compatible, however the "old" way of reading event logs, namely the `readEventLogFromFile` function is now **deprecated**.
**NOTE:** Users parsing large logs may notice that this version of the library is noticably slower than the older versions. The incremental parser is at fault here - previous versions of the libray used a "trick" that would let them essentially skip the first step of the mergesort algorithm since `EventBlock`s were already sorted in time order. The new parser reads the file incrementally and cannot take the advantage of this. Apologies for any inconvenience this may have caused.
