To install, just run the setup programme. There is no need to uninstall the previous version first (in fact, you should avoid doing so). Saved games created with previous versions are NOT compatible with this version.
Here's the changelist:
*** 0.9.26 (9 May 2015) ***
Bug fixes:
Various crashes fixed.
Display bug that resulted in crashes while viewing games at certain resolutions fixed.
SM-Liiga relegation series no longer played against team from incorrect league.
Playoff line in SM-Liiga standings screen now appears in correct place.
Teams now promoted to Allsvenskan from Swedish Division 1 instead of Russian junior league.
Goalie stat leaders lists no longer reduced to 2 players in some leagues.
NHL waivers now apply prior to the start of the regular season, so it's no longer possible to evade them by sending players down before the schedule starts.
KHL teams now consider nationality restrictions when making a trade.
AI teams should now offer picks earlier than the 5th round in trades.
NHL Draft no longer uses list of eligible nations that was excluding some countries - all IIHF nations should now be draft-eligible.
The league Player Stats and team Skater Stats 1 screen now default to a proper sort order (points, goals, games played.)
Changes:
Finnish Mestis is now playable (some bugs at the moment, roster limits are set too low and there are issues with playoffs/relegation/promotion.)
Mouse buttons 3 and 4 can now be used to go forward/back.
GAA and Save % added to goalie career stats and "Last 4" section.
Manager Options screen now includes single buttons to set all coaching/management options to the AI or user.
"Save as..." save option added.
Point totals now bolded in standings screens.
All positions rated 15 or higher now indicated at top of player screen, instead of just the highest one.
Farm teams now referred to on various screens by city name instead of nickname (where applicable.)
"Drafted from" team now indicated in draft report.
League logos now use the same format as historical logos (_year at the end of the name) so they can now change over time.
Retirements on non-playable teams are now handled mainly by the non-playable transactions system - this should end the mysterious prospect disappearances some people had noted.
Non-playable leagues now use additional categories of player movement (some major incompatibilities at the moment between the systems for moving players out of their league if they become too good/bad and the way the computer is assigning ratings to players with incomplete data at the start of the game - generally, those players aren't good enough, so it means a lot of guys retiring early. The player generation/ratings fill-in systems will be getting major overhauls in the next week or two.)
Size of potential destinations lists for nonplayable transactions expanded.
Team text colour now adjusted based on background color (this is a precursor to some larger improvements in the way team colours are handled, including full editability.)
Database Changes:
Players with NHL debuts up to 1993-94 now included in historical database.
Leagues/countries with significant amounts of updated data: NHL, AHL, NCAA, OHL, QMJHL, KHL, Czech Republic, Finland, UK.
