It was released in 2003. Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm. Such cameras, however, have more clearance, allowing lens elements to be closer to the sensor than in the EF mount. Only Canon cameras released after 2003 with APS-C sized sensors support the EF-S mount.

Because of its strategic location, bordering the national capital city of Washington D.C. with its District of Columbia since 1790, and the strong desire of the opposing factions within the state to sway public opinion towards their respective causes, Maryland would play an important role in the American Civil War (1861-1865). New sixteenth President Abraham Lincoln's suspension of habeas corpus in Maryland, and his dismissal of the U.S. Supreme Court's ``Ex parte Merryman'' decision concerning John Merryman, a prominent Southern sympathizer from Baltimore County held in Fort McHenry, now nicknamed ``Baltimore Bastille''. The Chief Justice supported by the Court had held that the suspension was unconstitutional, would leave lasting civil and legal scars. The court was led by Chief Justice Roger Brooke Taney, a Marylander from Frederick and sometimes in Baltimore and protege of seventh President Andrew Jackson who had appointed him two decades earlier.

However, the Bank of England does produce higher-value notes that are used to maintain parity with Scottish and Northern Irish notes. Banknotes issued by Scottish and Northern Irish banks have to be backed pound for pound by Bank of England notes (other than a small amount representing the currency in circulation in 1845), and special £1 million and £100 million notes are used for this purpose. Their design is based on the old Series A notes.

Although these batteries can be cycled down to 20% charge, the best lifespan vs cost method is to keep the average cycle at about 45% discharge. There is an inverse correlation between the depth of discharge (DOD) of the battery, and the number of charge and discharge cycles it can perform.
