Fixed a bug that allowed players to trigger a double ambush.
Fixed a bug that caused the player to continue traveling on foot even though they had received fuel through an achievement.
Added "--aggressive-gc" command line option. Using this option forces a memory garbage-collection after each event. When used, you'll likely experience a short delay each time the event window closes. While this parameter doesn't fix anything per se, it is supposed to help us narrowing down the out-of-memory crashes and performance issues.
Disabled use of separate render thread on MacOS. May be related to performance issues some user reported on MacOS 10.14 Mojave.

Tsioque has been updated.

Pillars of Eternity II: Deadfire

Update 5.0 (8 May 2019)

Ship Combat UI update - A new UI has been added that pops up when you encounter a ship, allowing for some immediate options. This bestows the ability to interact with ship combat for players that continue to enjoy it, while allowing a way to quickly choose a different options to avoid them such as boarding or parley.
Turn-based mode leaving Beta - Thank you to our players that have tested turn-based mode! This will now be set to live with the 5.0.0 patch.

The Book Of Woedica: Unfortunately, The Book of Woedica contains a bug that doesn't allow for Woedica's VO to be heard unless the player opens the book on the World Map due to technical limitations. We apologize for this inconvenience!

A Note from Narrative Designer Paul Kirsch: "After Deadfire's launch and public reception, leadership and the writing team closely scrutinized some of the narrative issues which could have presented better or required some clarification. We distilled the most prevalent issues down to a couple of core factors: a lack of clarity regarding the metaphysics of Eora, and missing connectivity between Deadfire's "god plot" and "faction plot," for lack of a better term. Shortly before launching The Forgotten Sanctum, those of us still attached to the project had some availability to address these concerns. A handful of developers pooled their efforts to execute on a plan that seeks to address these story problems through modestly-scoped, unobtrusive changes to the core game experience. What follows behind the Spoiler gate is a broad outline of the solutions we pursued. We hope you enjoy them. Thanks for reading, and thanks for playing!""
Expanded Eothas Dialogue - The end game with Eothas has had many new voiced lines added to address some pressing questions from the players.
Anarchist Path - Changes have been added to the Anarchist path to allow for more of the game to be experienced before the player can attempt to finish the game.

The Ultimate Challenge

The Ultimate Challenge is now available for those adventurers that dare try to brave it. Those that manage to best the challenge may even find themselves with physical rewards!

The Ultimate Challenge requires the following to be enabled/completed: Triple Crown - Expert Mode, Trial of Iron, Path of the Damned Level Scaling (Only scale upwards) Solo All 11 God Challenges - Wael, Woedica, Hylea, Rymrgand, Ondra, Skaen, Abydon, Magran, Berath, Galawain, and Eothas. All DLCs - Beast of Winter/ Seeker, Slayer Survivor/ Forgotten Sanctum. All major enemies and boss battles completed.
The Ultimate Challenge requires the following to be disabled: Console Command Cheats Mods Beraths Blessings

Pathway

Update 1.0.10 (8 May 2019)

Added a new hitchance preview when moving (see above)
First step towards event distribution overhaul (see above)
We reworked a number of events that previously had "hidden" perk options. These invisible options were automatically activated if a character on the team had the appropriate skill. Unfortunately this also meant that a lot of players missed out on content due them not being identifiable in any way. We've changed this and the options are now explicit as part of a choice the player can make if the appropriate perk is part of the team. Practically speaking, this means that some events have received new perk options!
We've reworked the structure of some events to be spread out over fewer pages, effectively reducing the amount of clicks needed. Some events had also their texts shortened where it made sense to do so in order to improve the overall flow.
Added a confirmation question if the player tries to leave the loot screen without touching any of the loot. It'll also ask for confirmation if the player leaves behind an epic or legendary item.
New savegame backup system: The game will now automatically create backups at relevant points. This is mainly in place so we can recover saves that may get corrupted when using the preview branch or for some other situations where a bug caused an unfair loss.
Bellamy can now also be unlocked by purchasing a Disintegrator weapon
Codex has been updated to include recent changes.
Time elapsed formatting in adventure stats now shows as hh:mm:ss
Fixed a bug that caused audio settings to not be properly preserved across game sessions.
Fixed a grammar mistake in one of Veduti's character comments.
Fixed a bug that made it impossible to revisit character rescue missions. They can now be revisited even if you didn't recruit the character right away or decided to not engage in combat previously.
Fixed some combat arena generators causing enemies to get trapped.
Fixed a country name on one of he loading screens maps
Fixed a rare crash that occurred when loading the game after updating to a new version
Fixed a bunch of wrong gender pronoun uses in event texts
Fixed a bug that caused the camera to move outside of the map bounds
Fixed a bug that caused the "The Coming War" achievement to not be attainable
Fixed a bug that allowed people to purchase fuel beyond the jeep's capacity at the merchant
Fixed a bug that caused the recruit icon to be invisible when on neighbouring location.
Fixed a bug that caused some event texts to overlap
Fixed a bug that would allow you to move items into the valuables bag when recruiting people.
Fixed a bug that caused Sporebearers to not automatically die when the last enemy was killed with a bleed attack.
Fixed a bug that allowed the player to open the codex during the enemy's turn even though the button was disabled.
