All Book of Dota guides have been updated to 7.19c. If you are wondering about the changes Icefrog made to the game, you can find them in the Dota 2 blog here. The new patch includes primarily nerfs to some of the meta heroes like WK, Ursa, Ench, etc.
We added some new community content to the Library, including D2Bowie's latest video - his ultimate guide to dewarding.
We also found a great new content creator - Captain Iceblock is a top 100 Storm player according to Dotabuff's player rankings and he makes awesome video guides like this Storm vs Meepo lane matchup guide. If you like his content make sure to subscribe to his YouTube channel so that we can ensure he'll continue making awesome vids in the future!
