Thanks to the efforts of David Vincent (R.I.P.), Baseball Reference has added originally scheduled dates of games that were made up later in the season or unplayed due to other circumstances. We have now incorporated that information into our team schedules from 1877 up to 2016, with the 2017 and 2018 seasons coming later on.
This information, which is part of the Retrosheet database, also includes the reason for the postponement or cancellation of the game. So now it's easier to know the 2007 Indians played their first "home" series in Milwaukee due to snow in Cleveland. In addition to weather-related postponements, we also mark games that were pushed due to more tragic events, such as the 1968 Pirates and several other teams that season delaying their openers due to the funeral for Martin Luther King Jr.
As a final note, a reminder that the reason there was a second game that had to be forefited on Disco Demolition Night was because of a rainout for a game previously scheduled on May 2, 1979.
For more information on the source and other contributors to this project, please refer to Retrosheet.

As you browse Baseball Reference, you might notice some subtle changes to WAR figures on the site. There are four main reasons for this:
- Park factors for recent seasons have been re-computed to be three-year rolling averages. For instance, 2016 Park Factors now encompass 2015-2017. This is something that needs to be done when seasons end.
- We've incorporated restated and expanded fielding statistics from Sports Info Solutions. SIS's Defensive Runs Saved forms the basis for our Defensive WAR calculations since 2003. From 2011 on they recalibrated data using their timer measures to measure ball hang time. There was also some recalculation based on changing shift methodology. Though we're now publishing their catcher framing stat (Strike Zone Runs Saved), we have not incorporated it into WAR at this time.
- Pitchers who received time as position players (whether PH or in the field) are now being treated as part-time pitchers and part-time position players. Previously we treated them as full-time pitchers. Some pitchers like Red Ruffing, Bob Lemon and Jim Kaat appeared in many games as a position player, pinch hitter or pinch runner. We used to credit these PAs as pitchers, which overvalued their offensive contributions. To handle this, we compute a percentage of time as a non-pitcher and make an adjustment.
- Also, we have incorporated a good deal more Retrosheet data which has affected the years we can compute more advanced fielding and baserunning measures. We're now able to roll these measures back to 1953. Another important change is that with Retrosheet gamelogs back to 1908, we can now use their IP data back to that year to get starter/relief IP splits. Some pitcher WAR changes for 1908-12 are due to WAR now being calculated using gamelog IP rather than the "official" total listed on the player's stat line. The biggest difference here was the appropriately named Bugs Raymond. The "official" record credits him with 324.1 IP that season, but the gamelogs come out to 304.1, which significantly impacted his WAR calculation (see below). For further reading on discrepancies between "official" records and more recently produced gamelogs, please read this excellent explainer by Retrosheet's Dave Smith.

Our friends at Sports Info Solutions (formerly known as Baseball Info Solutions) have provided us with a pitch framing measure back to 2011, which we have added to Baseball Reference. Before I explain any further, if you're unfamiliar with the concept of pitch framing please read Mike Fast's 2011 article on the topic and Ben Lindbergh's 2013 follow up.
The stat that we have added is called Strike Zone Runs Saved. It represents the runs saved by catcher framing. In our tables, it's labeled RszC and it's available from 2011 to the present. While this statistic is a potential component of Defensive Runs Saved (and therefore WAR), please note that we have elected to not integrate this number into DRS (or WAR) at this time. We may elect to do so in the future, but for now we agree with Bill James's stance that waiting for further research is a good idea.

You may have noticed that our homepage has upcoming Spring Training games listed in the MLB Probable Pitchers section. If you click on a team's name in that section, it will bring up their 2018 Spring Training stats. For instance, here's the 2018 Yankees Spring Training stats. We'll be updating the stats daily.
We also have this register of all 2018 Spring Training stats. If you're looking to access that page via the site, it can be found in the 2018 season menu under the batting or pitching dropdown.

Thanks to the efforts of our friends at Retrosheet, we have added box scores back to the 1908 season to Baseball Reference (previously, our coverage went back to 1913). Additionally, we have added play-by-play coverage for games games as far back as 1925. Previously, our oldest play-by-plays were from 1930. In addition to the boxes and PBPs themselves, this update allows for a variety of new information searchable in the play index, as well as new rows of information in team/player/league statistics tables.

You may have noticed that we added projections for 2018 to player and team pages last month. We have now added a register with all 2018 projections. See the batting projections here and the pitching projections here. These projections are very simple and are done in an automated way using Tom Tango's Marcels forecasting system, which you can read about here.
