Here's the latest update - delivered in a slightly different way than usual. Due to summer vacation, there will be little to no available developer support from now till July 18th. Until then, the update is an opt-in found via Properties->Beta in the Steam Client. Once the ability to respond quickly to support inquiries and push out hot fixes is restored, the build will be pushed to the main branch. Patch notes are as follows, a mix of battle system improvements and the (very early) beginnings of non-English language support.

• During battles hovering over a unit will display it's stats, attacks and abilities on a "unit card" panel. The display is sticky until hovering over a new unit, and has a minimize/maximize button.
• Spells can be cast during battles. Most battle spells do not have implemented effects yet and the ones that do, do not have any sound or visual effects yet.
• Implemented Fireball (battle spell). It deals 8 Fire damage to up to 10 targets in a unit.
• Implemented Power Word: Pain (battle spell). It deals 4 Dark damage to 20% of the targets in a unit. The unit suffers -1 Discipline, -1 Shock and -1 Melee Skill for 10 seconds if living and not mindless or hardy.
• Implemented Terrible Visage (battle spell). It gives the target unit the Terror special ability for 4 seconds. This ability reduces the effective courage of opposing units which are not mindless or terror-causing - and as such the spell can also be used to grant (temporary) immunity when faced with a terror-causing foe.
• Implemented Shrapnel (battle spell). It inflicts 25 + (25% of target unit size) hits for 4 Physical damage, increased to 6 if target unit has armor less than 3.
• Implemented Curse of Rust (battle spell). Reduces armor of a unit by 7 (down to 0). Can only target units with metal armor and/or the Metal tag.
• Added a pre-battle phase, where depending on the nature of the battle and opposing forces there may be one or more choices to make. These can affect the battle or even potentially avoid it (e.g. a successful retreat before battle occurs).
• Compression is now used to reduce the size of save game files.
• Optimized the save game code. As the majority of turn processing is taken up by the auto-save, this has a significant impact on turn processing speed.
• Battles can now be paused.
• Wizard Project cost penalty text has been changed to be more clear.
• The Battle Window now stays open when a battle ends, allowing the player time to read the log and inspect the battlefield, until clicking the close button.
• The Battle Window log now appends messages to the top instead of the bottom.
• Reworked physical damage bonus due to strength to depend on weapon-specific values and be less advantageous to strong units
• Changed battle window side-specific unit and log colors to be more readable and accommodate color-blindness.
• Foundations for localization/translation added. The language can be changed in the Game Settings window. Currently only the main menu is translated. Also note the list of languages is not final, and may or may not reflect the order in which localization occurs.
• Fixed issue with the text in the Wizard Project window being oddly aligned.
• Fixed issue with the text in the Construction Project window being oddly aligned.
• Fixed issue with army icons being minimized without reason.
• Fixed issue with charge status not being applied correctly during battles.
• Fixed issue with units being able to hit retreating enemies from a rather extreme distance with melee attacks
• Fixed issue with weird battle reports in the Encyclopedia for battles resolved via the new battle engine
• Fixed issue with the Demonic Strength spell being permanent instead of lasting 6 turns
